    A - Air Flow Design
    (back to chart)

    A1 - Laminar Flow/Positive Pressure

    Laminar flow air and positive pressure cleanroom design are ideal for non-hazardous, ultra-clean applications. Positive pressure mitigates dirt from entering the cleanroom when opening doors or pass-through chambers. Laminar airflow design ensures that air maintains a singular, uniform direction and velocity from intake to exhaust port. Terra's positive pressure cleanrooms include HEPA filtration systems capable of ISO Class 3 - ISO Class 8 air quality conditions. ULPA filtration units are available for the most sensitive ISO 3 - ISO 5 product applications including pharmaceutical compounding, semiconductor wafer processing, sterile packaging, and micro-nanofabrication.

    A2 - Laminar Flow/Negative Pressure

    A negative pressure laminar flow cleanroom is best suited for hazardous environments. Particularly, when the product is also sensitive or reactive to chemical, environmental, or particulate contamination. Negative pressure cleanrooms prevent the escape of toxic or hazardous air from the containment structure. Laminar airflow design ensures that air flows without interruption between intake and exhaust, which ensures that sterile or biologically sensitive samples remain pure and unadulterated. Terra's negative pressure cleanrooms provide capable and safe production environments for reducing operator hazards in high-risk applications such as USP 800 compounding, infectious disease research, and chemically intensive processes that require volatile chemical handling.

    Terra manufactures and designs cleanrooms to BSL-1 and BSL-2 criteria. Some operations that fall under BSL-2 may require single-pass air that is filtered before being exhausted to the outside; others may allow recirculation of air and release of unfiltered exhaust air.

    A3 - Ventilation/Negative Pressure

    Negative pressure ventilation rooms are designed for handling chemicals that produce toxic, carcinogenic, or noxious vapors. Reverse-flow FFUs capture particles generated in localized cleanroom spaces to minimize contamination and ensure operator protection. Vapor removal FFUs eliminate trace amounts of VOCs from make-up air to prevent chemical fume contamination. Depending on the application, a containment room may require exit filtration: either HEPA/ULPA filters for particles and aerosols and/or carbon filters to remove chemical fumes.

    A4 - Recirculation/Neutral Pressure

    A neutral pressure cleanroom system is designed to ventilate environmental nuisances away from the operator; it is not intended to provide personnel or environmental protection against hazardous substances. In some cases, the environment does not require any specific ISO-rated classification, thus the primary purpose is to isolate particulates and aerosols that would otherwise congregate in adjacent areas or corridors. If it is safe to do so, a recirculating cleanroom allows filtration and reintroduction of room air and reduces heating and energy costs. Neutral pressure is the least energy-intensive when compared to positive and negative pressure designs. Recirculating negative pressure cleanrooms are commonly selected for purity testing, weighing, capsulizing, and packaging pharmaceutical powders.

    A5 - Horizontal Flow/Positive Pressure

    Horizontally configured cleanrooms are advantageous when vertical space and ceiling access is limited or extra tall ceiling requirements. Ceiling height is an important consideration for cleanroom design, especially for large objects found within aerospace, satellite, and telescope manufacturing environments. Horizontal flow cleanrooms introduce air from fan filter units mounted within sidewalls instead of traditional ceiling-mounted blowers. Air moves in parallel with the floor instead of perpendicularly. Air flows from a side-wall integrated with HEPA fan filter units and exits through a parallel wall with an integrated plenum for air return or exhaust. Wall-to-wall laminar airflow is advantageous when handling small parts and liquids which would otherwise be problematic for vertical floor cleanrooms with grated false-flooring.

    B - Wall Panel Material
    (back to chart)

    B1 - Stainless Steel

    Stainless steel is a golden standard among cleanroom construction materials. Easy cleaning, favorable heat properties, and chemical resistance make stainless an ideal choice for biopharmaceutical and semiconductor environments. The smooth surface is easy to wipe down, resists biofilm buildup, and will not off-gas.

    B2 - Powder-Coated Steel

    Powder-coated steel is an economical choice that also provides favorable heat and chemical resistance for most applications. Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

    B3 - Acrylic

    Acrylic is widely used in cleanrooms and other critical environment applications. Its low initial cost, lightweight, transparency, and tensile strength makes it an attractive choice in many situations. Terra offers economical acrylic enclosures as a budget-friendly option. While acrylic is fairly durable against UV light and impact-resistant, the material is easily degraded by alcohols and solvents.

    B4 - Static Dissipative PVC

    Static-Dissipative PVC comes in rigid or flexible material for use on hardwall cleanroom panels or cleanroom curtains, dust covers, microenvironments, and other applications requiring a softer material. Non-dissipative plastics quickly accumulate surface charges that attract contaminants. Dissipative plastics prevent static build-up that attracts airborne particulate and lint fibers, which makes surfaces easier to wipe down. Static-dissipative PVC (SD-PVC) will not hold a static charge, offers wide chemical compatibility, and cleans easily. SD-PVC retains a surface resistivity of 10^6 - 10^8 ohms/square indefinitely unlike spray-on coatings that can wear off after a few years. SD-PVC also resists alcohol and most other sterilizing solutions, thus supporting standard disinfecting procedures and extending the life of your enclosure.

    B5 - Polycarbonate

    Polycarbonate is transparent with a slight gray tint and offers broad-spectrum chemical resistance, high impact resistance, and excellent thermal resistance (to 200°F / 93.3°C). Polycarbonate is stronger and cracks less easily than both acrylic (15x stronger) and glass (250x stronger).

    B6 - Polypropylene

    Polypropylene is an opaque thermoplastic with excellent chemical resistance against acids and solvents.

    B7 - Chlorinated PVC (C-PVC)

    Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels have excellent chemical resistance and prevent particle emission and microbial growth. Their unique solvent-free silicone adhesive allows installation on wallboard substrate creating a strong, rigid structure when mounted to Terra’s steel frame. Welded seams are trim-free, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning.

    B8 - Fiberglass Reinforced Plastic (FRP)

    Class A and C FRP panels feature a unique non-outgassing advanced polymer adhesive for installation on drywall or other substrates. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. A patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

    B9 - Tempered Glass

    Tempered cleanroom glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempered glass is not only impact resistance, but also ideal for its high visual clarity and aesthetic. Glass wall cleanrooms allow easy monitoring of operators and processes within the cleanroom and tend to appear larger and more spacious. Tempered glass is non-outgassing and chemical-resistant, making it ideal for frequent decontamination.

    B10 - Vinyl Curtains

    Cleanroom vinyl curtains are lightweight and rapidly installable for creating room partitions, isolating equipment and processes, or mobile isolation when configured with wheel casters. Curtain strips are available in either 4' -wide softwall panels made of blur-free 40 mil vinyl or 8” -wide strip curtains made of blur-free 60 mil vinyl. Static-Dissipative PVC vinyl includes built-in static inhibitors and is recommended for all cleanrooms to minimize particle cling. A T-Grid Mounting System allows suspension of curtains or strip shields from Terra's cleanroom ceiling grid.

    B11 - Modesty Panels

    Modesty panels provide the combined benefits of natural light while also maintaining a degree of privacy. These panels are ideal for multi-level cleanroom mezzanines that require additional office space or unclassified storage. Modesty panels include an opaque lower panel and upper panel of transparent glass or cleanroom-rated plastic such as polycarbonate or static dissipative PVC. A solid lower panel provides a balance of privacy while the transparent window allows the introduction of natural light and tends to make the space appear larger and less constricted.

    B12 - Insulated Panels

    A double-wall, insulated wall panel promotes a stable environment for long-term sample storage, cell cultivation, or high-volume process equipment. Terra's double-wall insulated panels are adaptable to the customer’s temperature range specifications and application requirements including cold rooms, incubation, and sound isolation. Double-wall construction with 1”-thick polyurethane insulation enhances cleanroom heating/cooling efficiency and thermal stability. Rigid foam insulation paired with a climate control system provides better temperature stability for applications that require raised flooring for true laminar flow. Double-wall structure allows air to circulate through the inter-wall plenum which further increases filtration and A/C efficiency in high-performance applications.

    B13 - Center-Mount Panels With Mirror-Finish Steel Brackets

    Most of Terra’s competitors affix the cleanroom wall panels directly to the frame (mounted on the internal or external side of the frame. With this design, replacing cleanroom wall panels is a cumbersome task and requires cleanroom shutdown. If the panels are affixed externally to the frame, installing coved flooring is virtually impossible and the customers are tasked with sterilizing the frame along with all of its crevices. If the panels are mounted internally, the customer loses precious cleanroom space. If the flooring is coved to the internal panels, the customer loses even more space. Terra’s center-mount panel design alleviates these issues.

    C - Frame Material
    (back to chart)

    C1 - Stainless Steel (<20% or -5" Hg)

    Unlike most competitors who offer only aluminum extruded frames, Terra Universal provides steel and stainless steel frame materials that maintain structural integrity far longer than aluminum under fire conditions. Terra Universal’s BioSafe stainless steel cleanrooms may be ideal for sterile applications since they are not affected by harsh wash-down chemicals.

    Double-Wall Steel Panels
    Double-wall panels, available in 304/316 stainless or powder-coated steel, create a freestanding structure for affixing a ceiling grid. Each panel consists of an inside and outside portion, which are joined by a compression ball-and-socket fastener. Once joined, the walls can be detached by means of magnetic-grip handles (not included). The hollow space created by these panels provides a convenient installation zone for electrical conduit, gas, and vacuum service line enhancing systems, cleanliness, and appearance. In controlled temperature applications, this void may be insulated to optimize thermal stability and reduce energy costs.

    All Steel BioSafe Cleanrooms
    Terra’s all-steel BioSafe® Modular Cleanroom creates a rigid, self-supporting structure without a separate frame or external bracing, a key advantage over other designs that require special permitting and contractor installation.

    316L Stainless steel contains the same corrosion-resistant materials as 316 but includes the added benefit of lower carbon content—eliminating the opportunity for excessive metallic contamination and making cracking less likely. Both 316 and 316L can withstand chlorides and chlorinated solutions, such as Spor-Klenz® and Isopropyl Acetate.

    C2 - Powder-Coated Steel

    Terra's powder-coated steel cleanroom frames support free-standing softwall spans of up to 20 feet without internal posts or ceiling suspension cables. If necessary, reinforcements are provided for high-clearance, long-span rooms. Reinforcements ensure stability and additional seismic requirements for particle-sensitive samples and analytical instruments.

    D – Standard Components
    (back to chart)

    D1 - Filter Fan Units (FFUs)

    Terra’s WhisperFlow® FFU’s feature UL-listed components and built-in baffles that quietly produce uniform laminar airflow across the face of the filter. UL-listed products meet the highest manufacturing standards and reduce the risk of damage, injuries, and electrical hazards.

    Smart® Fan Filter Units with EC Motors provide annual energy savings of nearly $500 per fan filter unit. The control card features industry-standard MODBUS® networking, precision speed control (1-100%), and closed-loop control capability for air pressure, airflow, and particle count sensors.

    Terra fan filter unit housings are configurable for room-side replaceable, explosion-proof, heated, and low-profile configurations. The same high performance fan filter units are found throughout Terra products including cleanrooms, laminar flow hoods, and containment systems. Filter fan units are stocked, pre-tested, crated, and ready for immediate shipment from Terra's distribution centers.

    D2 - LED Lights

    Terra's LED flat panel troffer lights include dimmable brightness and 5 selectable color temperatures to achieve the perfect balance of light including 3000K / 3500K / 4000K / 5000K / 6500K. When paired with Terra's cleanroom control panels, lighting control is available from a centralized location out of the cleanroom. Terra's power distribution modules (PDMs) allow connection of lighting and fan filter via quick connections that do not require hardwiring. LED panels are available with integrated backup batteries that allow for up to an hour of continued visibility in the case of a power failure.

    D3 - Control Panels

    Cleanroom Control Panels centralize control of cleanroom lighting, power, fan speed, and assignable groups.

    Standard Control Panels provide central control and connection of lights and filters. A Fan Filter Replacement Alarm provides a reliable, quantitative method for determining when a HEPA filter requires replacement. An optional Night Service Switch drops all Fan/Filter Units (FFUs) into a low-energy mode for nights and weekends.

    Smart® Control Panels connect to EC FFUs for individual or grouped fan control and remote monitoring of room differential pressure, particle counts, temperature, and humidity. Robust systems offer advanced control for up to 200 fan filter units and 16 independently controlled rooms.

    D4 - Power Distribution Modules (PDMs)

    PDMs allow the addition of ceiling fan/filter units and lights to meet any cleanliness requirement or to upgrade ISO levels or lighting levels after installation. Terra’s PDMs use 3-pin or 4-pin quick connect fittings to power all FFUs, and lights, no matter the cleanroom size. Hardwiring is only required to connect the Primary, Secondary, Booster, and Duplex PDM modules. Because no additional hard wiring is required to connect and disconnect power to additional lights and fan filters, contractors save time, money, and resources during cleanroom installation, expansion, or modification.

    D5 - Doors

    Standard doors with aluminum frames are available in either single or double door configurations and a choice of acrylic or static-dissipative PVC panels.

    Swing doors are either Left Hand Reverse (LHR) or Right Hand Reverse (RHR) when viewed from outside the cleanroom (dirty side) to minimize particulate impact on the cleanroom when the door opens.

    Cleanroom doors on prehung frames install easily for negative or positive pressure cleanrooms. Choose from swing-out or sliding doors that are UL leak-rated and suitable for ISO 4 - ISO 8 environments.

    BioSafe® 316L stainless steel doors have continuous seam welds for sterile and aseptic environments. Terra's BioSafe products forgo cracks and crevices known to harbor particles and microbes. Dual-pane, flush-mount windows minimize horizontal surfaces and crevices where contaminants collect.

    Fire-rated doors include insulated double stainless steel walls, wire-free construction, and a fire-rated glass-ceramic viewing window that is impact resistant.

    D6 - Windows

    Terra's cleanroom windows are compatible with any cleanroom wall material or thickness and designed for compliance within healthcare, pharmaceutical, and GMP manufacturing applications. These easy-to-clean, hygienic windows enhance the visibility of operations and foot traffic without jeopardizing GMP design standards.

    Flush-mount cleanroom windows easily and seamlessly install into modular and stick-built cleanrooms and labs. Developed specifically for aseptic requirements in bio-pharmaceutical and cGMP cleanrooms, these hygienic cleanroom windows bring more light and visibility to your workspace without compromising cleanliness requirements. Choose from easy-to-clean framed or frameless stainless steel designs. Fire-rated cleanroom window designs meet building code requirements to protect your employees, operations, and business.

    D7 - Filter Replacement Alarm System

    Fan filter replacement alarms provide automatic replacement alerts to avoid costly and unexpected operational interruptions. Alarms trigger an audible buzzer when differential pressure reaches an adjustable setpoint. Alarms provide a reliable method for establishing fan filter replacement intervals while also reducing the risk of electrical/fire hazards caused by overworked motors pushing against overloaded HEPA filters.

    BioSafe® cleanroom windows include compression fittings for fast, hardware-free installation. Framed and frameless designs are compliant with BSL-rated rooms and ISO 4-compliant spaces.

    E – Compatible Cleanroom Class
    (back to chart)

    ISO 14644-1 is a document issued by the International Standards Organization which classifies a controlled environment into six categories of air cleanliness. ISO 14644-1 supersedes previous standards for cleanroom testing and validation such as Federal Standard 209E (FS209E). While references to FS209E are still used, ISO 14644-1 is internationally endorsed for testing and validating a cleanroom that meets FDA, USP, GMP, CGMP, or EU standards. An ISO 14644-1 cleanroom is classified on a scale between ISO Class 3 to ISO Class 8. The ISO class for a particular room is determined for the entire room and not for individual components or materials.

    Terra hardwall and BioSafe cleanrooms are configurable for the cleanest ISO 3 - 5 applications including wafer fabrication, microelectronics, nanotechnology, and sterile or biologically sensitive processes. Most industries fall within ISO 6 - ISO 8 cleanroom requirements including medical devices, general manufacturing, electronics assembly, food/beverage, and particulate or aerosol enclosures. Terra's modular hardwall configurations are available in steel, stainless steel, and plastic panels for ISO 5 - ISO 8 spaces with precise particulate and climate control requirements. ValuLine Softwall Modular Cleanrooms configurations are economical for less intensive or non-classified environments and available with preconfigured and ready-to-ship options.

    F – Air Conditioning
    (back to chart)

    F1 - Temperature

    Terra will work with a local HVAC contractor to provide an air control system that meets your cooling requirements and local codes. If the existing HVAC system cannot be used, Terra will provide the ducting and recirculation system that routes exhaust air to the compressor and delivers cool air to the ceiling FFUs in ample volume to maintain the desired air velocity inside the enclosure. Additional Cleanroom A/C Module provides economical cooling in facilities without adequate HVAC. Based on the cleanroom size, desired temperature, and heat dissipated inside the cleanroom, Terra will configure the appropriate number of AC units required for the space. With larger cleanrooms, Terra works with a local contractor to install a split A/C system, which moves the heat-generating compressor outside the building to reduce heat loads inside the facility.

    F2 - Humidification

    Terra’s Ultrasonic Humidifier is designed to be a turnkey system as an addition to your cleanroom. Simply place and rest the unit on an open 2’x4’ ceiling grid from above the cleanroom. No fasteners or gaskets are required to secure the unit in place. The system uses five ultrasonic transducers to generate mist and operates on only 150W, less power than conventional steam canister humidifiers. Humidification and dehumidification modules are controlled by a humidistat independent of the thermostat. The Ultrasonic Humidifier comes with a remote control to turn on the unit and set your desired RH levels (up to 100% RH).

    F3 - Dehumidification

    Cleanroom Dehumidification Modules use silica gel desiccant housed in a rotor to produce dry airflow.

    F4 - AC Module Interface

    Air Conditioning Modules provide economical cooling in facilities without adequate HVAC. Air Conditioning Modules incorporate dehumidification circuitry and are controlled by a humidistat independent of the thermostat. The unit includes a powder-coated steel air distribution plenum mounted to the external cleanroom wall, which provides conditioned air to up to six FFUs.

    Terra can provide custom HVAC modules that operate similarly to an environmental test chamber, adjusting the supply air's temperature and humidity to maintain specific conditions within tight tolerances. This type of system is particularly useful when the environment immediately outside of the cleanroom experiences significant fluctuations in temperature or relative humidity.

    G – Environmental Monitoring
    (back to chart)

    Smart® Fan Filter Power & Control Panels centralize control over assignable groups or specific targets when conducting cleanroom pressure-balancing, troubleshooting, or maintenance. An upgraded Smart Control System allows additional environmental sensors and FFU control to meet critical performance/monitoring requirements. A control panel assembly includes power controls for the Fan/Filter Units, lights, and is configurable for other integrations including temperature, humidity, particle counts, differential pressure, and air velocity sensors.

    G1 - Temperature

    Terra's thermometers, hygrometers, and data recording instruments help monitor, control, and document environmental conditions in your cleanroom or laboratory. Temperature, dew point, and humidity monitoring are essential for products with known sensitivities to heat, environmental drift, static, or trace moisture. Terra Universal provides decades of field-proven expertise and a wide selection of thermometers and sensors for complete room monitoring.

    G2 - Humidity

    Many labs and cleanrooms choose to maintain a 30% RH level. Anything more than that may cause other issues, such as damage to moisture-sensitive materials. Every Terra cleanroom is available with integrated sensors and monitoring equipment for measuring and recording relative humidity values within the cleanroom.

    G3 - Differential Pressure

    Magnehelic® Differential Pressure Gauges monitor room-to-room pressure or filter back-pressure. Digital and alarm models are available for activating alerts when pressures fall out of specification.

    G4 - Particle Counting

    Particle counters are available as standalone handheld units for spot-checking and validation, or as built-in modules for remote monitoring after connection to a centralized building management system (BMS) such as MODBUS.

    H – Ventilation & Contaminate Control
    (back to chart)

    H1 - False Ceiling Exhaust

    False Ceiling Exhaust: Use of a plenum mounted above the drop ceiling to divert air away from the work area. A false ceiling exhaust includes an array of ceiling-mounted reverse flow fan filter units. Reverse fan filter designs remove air from the work environment and port to an outside environment or dedicated HVAC exhaust. Reverse flow fan filter units mount to the ceiling grid and are available with integrated blowers, or with motorless designs for connection to a remote HVAC blower.

    H2 - False Floor Exhaust (Complete Laminarity)

    False Floor Exhaust: Raised grated or air-permeable flooring with bottom plenum underneath to achieve full airflow laminarity. False floor exhaust systems, also known as pass through floor exhausts, feature a grated flooring that provides unidirectional airflow and passage of contaminated air. Raised flooring is common for semiconductor applications and ideal for cleanroom classifications below ISO 5 to optimize vertical laminar flow.

    p - Floor-Mounted Exhaust

    Floor-Mounted Exhausts use side-wall plenums and floor-mounted air handlers to divert air away from the work area. The plenum is mounted directly to the frame and connects to ceiling ducts that exhaust air from the negative pressure room. Floor mount exhausts include internal airflow baffles to smooth corner flow and a pass vent at the bottom with an optional fixed position damper. Containment (negative pressure) rooms require customer furnished in-house exhaust systems capable of pulling the air volume required to create adequate negative pressure

    H4 - Biosafety Levels I & II

    Biosafety Level 1 is specified as work with well-characterized agents that are known to cause disease in healthy, non-immunocompromised adults. Special containment practices and devices are generally not required, but institutional laboratory practices must be implemented to reduce risk to laboratory personnel.

    Biosafety Level 2 is specified as work that poses moderate hazards to personnel and the environment. Research or diagnostic activities that are administered with pathogenic bacteria, such as Staphylococcus aureus or Salmonella, fall into this category. This Biosafety Level builds upon Biosafety Level 1; all of the precautions and practices spelled out in Biosafety Level 1 must be followed in addition to those found in Biosafety Level 2. Special containment practices and devices are generally required to mitigate risk to laboratory personnel.

    I – Upgraded Features
    (back to chart)

    I1 - Ion Bars

    Ionization bars neutralize electrostatic charges, a common requirement for mixing, packaging, or high-speed assembly lines. Static ionizing bars remove errant charges and have special importance for products with insulative properties.

    I2 - Air Curtains

    Air curtains produce a jetstream of ULPA Class 10 micro-filtered air at the entry and exit points of a controlled environment. Air curtains are ideal when doors are frequently opened or for doorless entryways. Operating modes include either motion sensor activation with adjustable delay or continuous operation.

    I3 - Uninterrupted Power Supply

    An uninterrupted power supply (UPS) is only used to maintain power in the cleanroom for a brief time during an unanticipated power outage. A UPS guarantees uninterrupted visibility inside a cleanroom in the event of power loss and provides power for one light (LED or fluorescent) for one hour.

    I4 - Cleanroom Emergency Lights

    The cleanroom emergency light is an LED light with a backup battery that will remain on during a power outage so employees can see well enough to shut down operations, secure any sensitive products, and evacuate safely in the case that power cannot be immediately restored.

    The LED light has a red/green indicator to inform employees after power has returned and the cleanroom is safe to re-enter. When receiving power, the light both operates normally and charges the emergency battery.

    I5 - Germicidal UV Lights

    UV sanitizing modules affix to the cleanroom ceiling grid to neutralize bacteria, viruses, and mold spores. UV light is particularly effective when targeting resistant bacteria, mold/fungal spores, and gram-negative microbes. The UV-C Germicidal Lamps install on a cleanroom ceiling grid for line-of-sight room disinfection. A safety occupancy sensor switches off the UVC lighting to prevent radiation exposure when occupied.

    I6 - Fire Detection System

    Terra provides fire detection and suppression systems ideal for wet benches, exhaust fume lines, and locations involving volatile chemicals. Terra cleanrooms support traditional sprinkler and heat sensor configurations or CO2-based suppression systems. The FS System 7 is an integrated fire detection and CO2 suppression system that includes electro-optical sensors for detecting any type of hydrocarbon or non-hydrocarbon fire, even through gas or vapor. A dual-stage alarm triggers an early warning for fires too small to be sensed by overhead sprinklers. An intelligent multi-stage response system prevents the damaging effects of fire suppression in the case that a small fire self-extinguishes or is suppressed rapidly. Terra engineers work with you to determine the fire suppression system appropriate for your requirements and local fire codes.

    I7 - Fingerprint Scanner

    Biometric fingerprint scanners prevent unauthorized access via shared keys or passwords while also providing data logging capability. An integrated proximity card reader enables two-factor authentication.

    I8 - Iris Scanner

    Fully automated iris scanner for secure, hands-free access (includes data logging and optional secondary keycard reader).

    I9 - Keycard Reader

    Keycard readers provide a durable and economical method for maintaining secured keycard access within a cleanroom facility. The low-profile device reads cards up to 3" away and integrates with access control software for data logging and remote monitoring.

    I10 - Pass Through

    General-Use Pass-Through Chambers are an economical choice for non-sterile items with a low risk of cross-contamination potential including samples, fluids, tools, packaging, or documents.

    ValuLine™ Pass-Through Chambers are configurable with economical black acrylic, chemical resistance polypropylene, or stainless steel for unmatched cleanliness and durability within cleanrooms.

    BioSafe® Pass-Through chambers with continuous seam welds eliminate hard-to-clean cracks and crevices that can harbor particles and germs. CleanSeam™ design conceals the door interlock mechanism behind the chamber’s wall for a completely unobstructed, easy-to-clean chamber interior.

    I11 - Talk Through

    Communication and vocal clarity are critical for successful outcomes within cleanrooms, laboratory, and hospital isolation environments. Mechanical and electronic talkthroughs allow easier communication between internal partitions or outside areas of the cleanroom. Both the mechanical and electronic talk throughs include cleanroom-grade components and are easy to mount in either a stick-built cleanroom wall or Terra hardwall modular cleanroom.

    I12 - Interlocking Doors

    Interlocking doors are common for passthrough chambers and air showers. The interlock prevents doors on either side of the enclosure from opening at the same time. Single side access helps to maintain airflow cascades between rooms of differing pressure and limits room pressure loss after opening and closing of doors.

    Air Flow Design Wall Panel Material Frame Material Standard Components Compatible Cleanroom Class Air Conditioning Environmental Monitoring Ventilation & Contaminate Control Upgraded Features Services

    A - Air Flow Design
    (back to chart)

    A1 - Laminar Flow/Positive Pressure

    Laminar flow air and positive pressure cleanroom design are ideal for non-hazardous, ultra-clean applications. Positive pressure mitigates dirt from entering the cleanroom when opening doors or pass-through chambers. Laminar airflow design ensures that air maintains a singular, uniform direction and velocity from intake to exhaust port. Terra's positive pressure cleanrooms include HEPA filtration systems capable of ISO Class 3 - ISO Class 8 air quality conditions. ULPA filtration units are available for the most sensitive ISO 3 - ISO 5 product applications including pharmaceutical compounding, semiconductor wafer processing, sterile packaging, and micro-nanofabrication.

    A2 - Laminar Flow/Negative Pressure

    A negative pressure laminar flow cleanroom is best suited for hazardous environments. Particularly, when the product is also sensitive or reactive to chemical, environmental, or particulate contamination. Negative pressure cleanrooms prevent the escape of toxic or hazardous air from the containment structure. Laminar airflow design ensures that air flows without interruption between intake and exhaust, which ensures that sterile or biologically sensitive samples remain pure and unadulterated. Terra's negative pressure cleanrooms provide capable and safe production environments for reducing operator hazards in high-risk applications such as USP 800 compounding, infectious disease research, and chemically intensive processes that require volatile chemical handling.

    Terra manufactures and designs cleanrooms to BSL-1 and BSL-2 criteria. Some operations that fall under BSL-2 may require single-pass air that is filtered before being exhausted to the outside; others may allow recirculation of air and release of unfiltered exhaust air.

    A3 - Ventilation/Negative Pressure

    Negative pressure ventilation rooms are designed for handling chemicals that produce toxic, carcinogenic, or noxious vapors. Reverse-flow FFUs capture particles generated in localized cleanroom spaces to minimize contamination and ensure operator protection. Vapor removal FFUs eliminate trace amounts of VOCs from make-up air to prevent chemical fume contamination. Depending on the application, a containment room may require exit filtration: either HEPA/ULPA filters for particles and aerosols and/or carbon filters to remove chemical fumes.

    A4 - Recirculation/Neutral Pressure

    A neutral pressure cleanroom system is designed to ventilate environmental nuisances away from the operator; it is not intended to provide personnel or environmental protection against hazardous substances. In some cases, the environment does not require any specific ISO-rated classification, thus the primary purpose is to isolate particulates and aerosols that would otherwise congregate in adjacent areas or corridors. If it is safe to do so, a recirculating cleanroom allows filtration and reintroduction of room air and reduces heating and energy costs. Neutral pressure is the least energy-intensive when compared to positive and negative pressure designs. Recirculating negative pressure cleanrooms are commonly selected for purity testing, weighing, capsulizing, and packaging pharmaceutical powders.

    A5 - Horizontal Flow/Positive Pressure

    Horizontally configured cleanrooms are advantageous when vertical space and ceiling access is limited or extra tall ceiling requirements. Ceiling height is an important consideration for cleanroom design, especially for large objects found within aerospace, satellite, and telescope manufacturing environments. Horizontal flow cleanrooms introduce air from fan filter units mounted within sidewalls instead of traditional ceiling-mounted blowers. Air moves in parallel with the floor instead of perpendicularly. Air flows from a side-wall integrated with HEPA fan filter units and exits through a parallel wall with an integrated plenum for air return or exhaust. Wall-to-wall laminar airflow is advantageous when handling small parts and liquids which would otherwise be problematic for vertical floor cleanrooms with grated false-flooring.

    B - Wall Panel Material
    (back to chart)

    B1 - Stainless Steel

    Stainless steel is a golden standard among cleanroom construction materials. Easy cleaning, favorable heat properties, and chemical resistance make stainless an ideal choice for biopharmaceutical and semiconductor environments. The smooth surface is easy to wipe down, resists biofilm buildup, and will not off-gas.

    B2 - Powder-Coated Steel

    Powder-coated steel is an economical choice that also provides favorable heat and chemical resistance for most applications. Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

    B3 - Acrylic

    Acrylic is widely used in cleanrooms and other critical environment applications. Its low initial cost, lightweight, transparency, and tensile strength makes it an attractive choice in many situations. Terra offers economical acrylic enclosures as a budget-friendly option. While acrylic is fairly durable against UV light and impact-resistant, the material is easily degraded by alcohols and solvents.

    B4 - Static Dissipative PVC

    Static-Dissipative PVC comes in rigid or flexible material for use on hardwall cleanroom panels or cleanroom curtains, dust covers, microenvironments, and other applications requiring a softer material. Non-dissipative plastics quickly accumulate surface charges that attract contaminants. Dissipative plastics prevent static build-up that attracts airborne particulate and lint fibers, which makes surfaces easier to wipe down. Static-dissipative PVC (SD-PVC) will not hold a static charge, offers wide chemical compatibility, and cleans easily. SD-PVC retains a surface resistivity of 10^6 - 10^8 ohms/square indefinitely unlike spray-on coatings that can wear off after a few years. SD-PVC also resists alcohol and most other sterilizing solutions, thus supporting standard disinfecting procedures and extending the life of your enclosure.

    B5 - Polycarbonate

    Polycarbonate is transparent with a slight gray tint and offers broad-spectrum chemical resistance, high impact resistance, and excellent thermal resistance (to 200°F / 93.3°C). Polycarbonate is stronger and cracks less easily than both acrylic (15x stronger) and glass (250x stronger).

    B6 - Polypropylene

    Polypropylene is an opaque thermoplastic with excellent chemical resistance against acids and solvents.

    B7 - Chlorinated PVC (C-PVC)

    Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels have excellent chemical resistance and prevent particle emission and microbial growth. Their unique solvent-free silicone adhesive allows installation on wallboard substrate creating a strong, rigid structure when mounted to Terra’s steel frame. Welded seams are trim-free, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning.

    B8 - Fiberglass Reinforced Plastic (FRP)

    Class A and C FRP panels feature a unique non-outgassing advanced polymer adhesive for installation on drywall or other substrates. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. A patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

    B9 - Tempered Glass

    Tempered cleanroom glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempered glass is not only impact resistance, but also ideal for its high visual clarity and aesthetic. Glass wall cleanrooms allow easy monitoring of operators and processes within the cleanroom and tend to appear larger and more spacious. Tempered glass is non-outgassing and chemical-resistant, making it ideal for frequent decontamination.

    B10 - Vinyl Curtains

    Cleanroom vinyl curtains are lightweight and rapidly installable for creating room partitions, isolating equipment and processes, or mobile isolation when configured with wheel casters. Curtain strips are available in either 4' -wide softwall panels made of blur-free 40 mil vinyl or 8” -wide strip curtains made of blur-free 60 mil vinyl. Static-Dissipative PVC vinyl includes built-in static inhibitors and is recommended for all cleanrooms to minimize particle cling. A T-Grid Mounting System allows suspension of curtains or strip shields from Terra's cleanroom ceiling grid.

    B11 - Modesty Panels

    Modesty panels provide the combined benefits of natural light while also maintaining a degree of privacy. These panels are ideal for multi-level cleanroom mezzanines that require additional office space or unclassified storage. Modesty panels include an opaque lower panel and upper panel of transparent glass or cleanroom-rated plastic such as polycarbonate or static dissipative PVC. A solid lower panel provides a balance of privacy while the transparent window allows the introduction of natural light and tends to make the space appear larger and less constricted.

    B12 - Insulated Panels

    A double-wall, insulated wall panel promotes a stable environment for long-term sample storage, cell cultivation, or high-volume process equipment. Terra's double-wall insulated panels are adaptable to the customer’s temperature range specifications and application requirements including cold rooms, incubation, and sound isolation. Double-wall construction with 1”-thick polyurethane insulation enhances cleanroom heating/cooling efficiency and thermal stability. Rigid foam insulation paired with a climate control system provides better temperature stability for applications that require raised flooring for true laminar flow. Double-wall structure allows air to circulate through the inter-wall plenum which further increases filtration and A/C efficiency in high-performance applications.

    B13 - Center-Mount Panels With Mirror-Finish Steel Brackets

    Most of Terra’s competitors affix the cleanroom wall panels directly to the frame (mounted on the internal or external side of the frame. With this design, replacing cleanroom wall panels is a cumbersome task and requires cleanroom shutdown. If the panels are affixed externally to the frame, installing coved flooring is virtually impossible and the customers are tasked with sterilizing the frame along with all of its crevices. If the panels are mounted internally, the customer loses precious cleanroom space. If the flooring is coved to the internal panels, the customer loses even more space. Terra’s center-mount panel design alleviates these issues.

    C - Frame Material
    (back to chart)

    C1 - Stainless Steel (<20% or -5" Hg)

    Unlike most competitors who offer only aluminum extruded frames, Terra Universal provides steel and stainless steel frame materials that maintain structural integrity far longer than aluminum under fire conditions. Terra Universal’s BioSafe stainless steel cleanrooms may be ideal for sterile applications since they are not affected by harsh wash-down chemicals.

    Double-Wall Steel Panels
    Double-wall panels, available in 304/316 stainless or powder-coated steel, create a freestanding structure for affixing a ceiling grid. Each panel consists of an inside and outside portion, which are joined by a compression ball-and-socket fastener. Once joined, the walls can be detached by means of magnetic-grip handles (not included). The hollow space created by these panels provides a convenient installation zone for electrical conduit, gas, and vacuum service line enhancing systems, cleanliness, and appearance. In controlled temperature applications, this void may be insulated to optimize thermal stability and reduce energy costs.

    All Steel BioSafe Cleanrooms
    Terra’s all-steel BioSafe® Modular Cleanroom creates a rigid, self-supporting structure without a separate frame or external bracing, a key advantage over other designs that require special permitting and contractor installation.

    316L Stainless steel contains the same corrosion-resistant materials as 316 but includes the added benefit of lower carbon content—eliminating the opportunity for excessive metallic contamination and making cracking less likely. Both 316 and 316L can withstand chlorides and chlorinated solutions, such as Spor-Klenz® and Isopropyl Acetate.

    C2 - Powder-Coated Steel

    Terra's powder-coated steel cleanroom frames support free-standing softwall spans of up to 20 feet without internal posts or ceiling suspension cables. If necessary, reinforcements are provided for high-clearance, long-span rooms. Reinforcements ensure stability and additional seismic requirements for particle-sensitive samples and analytical instruments.

    • Excellent for cleanroom applications
    • Good weather resistance
    • Good mechanical properties
    • Good chemical resistance
    • Excellent UV protection
    • Good storage stability
    • Underwriter Laboratories recognized component (UL approved)

    D – Standard Components
    (back to chart)

    D1 - Filter Fan Units (FFUs)

    Terra’s WhisperFlow® FFU’s feature UL-listed components and built-in baffles that quietly produce uniform laminar airflow across the face of the filter. UL-listed products meet the highest manufacturing standards and reduce the risk of damage, injuries, and electrical hazards.

    Smart® Fan Filter Units with EC Motors provide annual energy savings of nearly $500 per fan filter unit. The control card features industry-standard MODBUS® networking, precision speed control (1-100%), and closed-loop control capability for air pressure, airflow, and particle count sensors.

    Terra fan filter unit housings are configurable for room-side replaceable, explosion-proof, heated, and low-profile configurations. The same high performance fan filter units are found throughout Terra products including cleanrooms, laminar flow hoods, and containment systems. Filter fan units are stocked, pre-tested, crated, and ready for immediate shipment from Terra's distribution centers.

    D2 - LED Lights

    Terra's LED flat panel troffer lights include dimmable brightness and 5 selectable color temperatures to achieve the perfect balance of light including 3000K / 3500K / 4000K / 5000K / 6500K. When paired with Terra's cleanroom control panels, lighting control is available from a centralized location out of the cleanroom. Terra's power distribution modules (PDMs) allow connection of lighting and fan filter via quick connections that do not require hardwiring. LED panels are available with integrated backup batteries that allow for up to an hour of continued visibility in the case of a power failure.

    D3 - Control Panels

    Cleanroom Control Panels centralize control of cleanroom lighting, power, fan speed, and assignable groups.

    Standard Control Panels provide central control and connection of lights and filters. A Fan Filter Replacement Alarm provides a reliable, quantitative method for determining when a HEPA filter requires replacement. An optional Night Service Switch drops all Fan/Filter Units (FFUs) into a low-energy mode for nights and weekends.

    Smart® Control Panels connect to EC FFUs for individual or grouped fan control and remote monitoring of room differential pressure, particle counts, temperature, and humidity. Robust systems offer advanced control for up to 200 fan filter units and 16 independently controlled rooms.

    D4 - Power Distribution Modules (PDMs)

    PDMs allow the addition of ceiling fan/filter units and lights to meet any cleanliness requirement or to upgrade ISO levels or lighting levels after installation. Terra’s PDMs use 3-pin or 4-pin quick connect fittings to power all FFUs, and lights, no matter the cleanroom size. Hardwiring is only required to connect the Primary, Secondary, Booster, and Duplex PDM modules. Because no additional hard wiring is required to connect and disconnect power to additional lights and fan filters, contractors save time, money, and resources during cleanroom installation, expansion, or modification.

    D5 - Doors

    Standard doors with aluminum frames are available in either single or double door configurations and a choice of acrylic or static-dissipative PVC panels.

    Swing doors are either Left Hand Reverse (LHR) or Right Hand Reverse (RHR) when viewed from outside the cleanroom (dirty side) to minimize particulate impact on the cleanroom when the door opens.

    Cleanroom doors on prehung frames install easily for negative or positive pressure cleanrooms. Choose from swing-out or sliding doors that are UL leak-rated and suitable for ISO 4 - ISO 8 environments.

    BioSafe® 316L stainless steel doors have continuous seam welds for sterile and aseptic environments. Terra's BioSafe products forgo cracks and crevices known to harbor particles and microbes. Dual-pane, flush-mount windows minimize horizontal surfaces and crevices where contaminants collect.

    Fire-rated doors include insulated double stainless steel walls, wire-free construction, and a fire-rated glass-ceramic viewing window that is impact resistant.

    D6 - Windows

    Terra's cleanroom windows are compatible with any cleanroom wall material or thickness and designed for compliance within healthcare, pharmaceutical, and GMP manufacturing applications. These easy-to-clean, hygienic windows enhance the visibility of operations and foot traffic without jeopardizing GMP design standards.

    Flush-mount cleanroom windows easily and seamlessly install into modular and stick-built cleanrooms and labs. Developed specifically for aseptic requirements in bio-pharmaceutical and cGMP cleanrooms, these hygienic cleanroom windows bring more light and visibility to your workspace without compromising cleanliness requirements. Choose from easy-to-clean framed or frameless stainless steel designs. Fire-rated cleanroom window designs meet building code requirements to protect your employees, operations, and business.

    D7 - Filter Replacement Alarm System

    Fan filter replacement alarms provide automatic replacement alerts to avoid costly and unexpected operational interruptions. Alarms trigger an audible buzzer when differential pressure reaches an adjustable setpoint. Alarms provide a reliable method for establishing fan filter replacement intervals while also reducing the risk of electrical/fire hazards caused by overworked motors pushing against overloaded HEPA filters.

    BioSafe® cleanroom windows include compression fittings for fast, hardware-free installation. Framed and frameless designs are compliant with BSL-rated rooms and ISO 4-compliant spaces.

    E – Compatible Cleanroom Class
    (back to chart)

    ISO 14644-1 is a document issued by the International Standards Organization which classifies a controlled environment into six categories of air cleanliness. ISO 14644-1 supersedes previous standards for cleanroom testing and validation such as Federal Standard 209E (FS209E). While references to FS209E are still used, ISO 14644-1 is internationally endorsed for testing and validating a cleanroom that meets FDA, USP, GMP, CGMP, or EU standards. An ISO 14644-1 cleanroom is classified on a scale between ISO Class 3 to ISO Class 8. The ISO class for a particular room is determined for the entire room and not for individual components or materials.

    Terra hardwall and BioSafe cleanrooms are configurable for the cleanest ISO 3 - 5 applications including wafer fabrication, microelectronics, nanotechnology, and sterile or biologically sensitive processes. Most industries fall within ISO 6 - ISO 8 cleanroom requirements including medical devices, general manufacturing, electronics assembly, food/beverage, and particulate or aerosol enclosures. Terra's modular hardwall configurations are available in steel, stainless steel, and plastic panels for ISO 5 - ISO 8 spaces with precise particulate and climate control requirements. ValuLine Softwall Modular Cleanrooms configurations are economical for less intensive or non-classified environments and available with preconfigured and ready-to-ship options.

    F – Air Conditioning
    (back to chart)

    F1 - Temperature

    Terra will work with a local HVAC contractor to provide an air control system that meets your cooling requirements and local codes. If the existing HVAC system cannot be used, Terra will provide the ducting and recirculation system that routes exhaust air to the compressor and delivers cool air to the ceiling FFUs in ample volume to maintain the desired air velocity inside the enclosure. Additional Cleanroom A/C Module provides economical cooling in facilities without adequate HVAC. Based on the cleanroom size, desired temperature, and heat dissipated inside the cleanroom, Terra will configure the appropriate number of AC units required for the space. With larger cleanrooms, Terra works with a local contractor to install a split A/C system, which moves the heat-generating compressor outside the building to reduce heat loads inside the facility.

    F2 - Humidification

    Terra’s Ultrasonic Humidifier is designed to be a turnkey system as an addition to your cleanroom. Simply place and rest the unit on an open 2’x4’ ceiling grid from above the cleanroom. No fasteners or gaskets are required to secure the unit in place. The system uses five ultrasonic transducers to generate mist and operates on only 150W, less power than conventional steam canister humidifiers. Humidification and dehumidification modules are controlled by a humidistat independent of the thermostat. The Ultrasonic Humidifier comes with a remote control to turn on the unit and set your desired RH levels (up to 100% RH).

    F3 - Dehumidification

    Cleanroom Dehumidification Modules use silica gel desiccant housed in a rotor to produce dry airflow.

    F4 - AC Module Interface

    Air Conditioning Modules provide economical cooling in facilities without adequate HVAC. Air Conditioning Modules incorporate dehumidification circuitry and are controlled by a humidistat independent of the thermostat. The unit includes a powder-coated steel air distribution plenum mounted to the external cleanroom wall, which provides conditioned air to up to six FFUs.

    Terra can provide custom HVAC modules that operate similarly to an environmental test chamber, adjusting the supply air's temperature and humidity to maintain specific conditions within tight tolerances. This type of system is particularly useful when the environment immediately outside of the cleanroom experiences significant fluctuations in temperature or relative humidity.

    G – Environmental Monitoring
    (back to chart)

    Smart® Fan Filter Power & Control Panels centralize control over assignable groups or specific targets when conducting cleanroom pressure-balancing, troubleshooting, or maintenance. An upgraded Smart Control System allows additional environmental sensors and FFU control to meet critical performance/monitoring requirements. A control panel assembly includes power controls for the Fan/Filter Units, lights, and is configurable for other integrations including temperature, humidity, particle counts, differential pressure, and air velocity sensors.

    G1 - Temperature

    Terra's thermometers, hygrometers, and data recording instruments help monitor, control, and document environmental conditions in your cleanroom or laboratory. Temperature, dew point, and humidity monitoring are essential for products with known sensitivities to heat, environmental drift, static, or trace moisture. Terra Universal provides decades of field-proven expertise and a wide selection of thermometers and sensors for complete room monitoring.

    G2 - Humidity

    Many labs and cleanrooms choose to maintain a 30% RH level. Anything more than that may cause other issues, such as damage to moisture-sensitive materials. Every Terra cleanroom is available with integrated sensors and monitoring equipment for measuring and recording relative humidity values within the cleanroom.

    G3 - Differential Pressure

    Magnehelic® Differential Pressure Gauges monitor room-to-room pressure or filter back-pressure. Digital and alarm models are available for activating alerts when pressures fall out of specification.

    G4 - Particle Counting

    Particle counters are available as standalone handheld units for spot-checking and validation, or as built-in modules for remote monitoring after connection to a centralized building management system (BMS) such as MODBUS.

    H – Ventilation & Contaminate Control
    (back to chart)

    H1 - False Ceiling Exhaust

    False Ceiling Exhaust: Use of a plenum mounted above the drop ceiling to divert air away from the work area. A false ceiling exhaust includes an array of ceiling-mounted reverse flow fan filter units. Reverse fan filter designs remove air from the work environment and port to an outside environment or dedicated HVAC exhaust. Reverse flow fan filter units mount to the ceiling grid and are available with integrated blowers, or with motorless designs for connection to a remote HVAC blower.

    H2 - False Floor Exhaust (Complete Laminarity)

    False Floor Exhaust: Raised grated or air-permeable flooring with bottom plenum underneath to achieve full airflow laminarity. False floor exhaust systems, also known as pass through floor exhausts, feature a grated flooring that provides unidirectional airflow and passage of contaminated air. Raised flooring is common for semiconductor applications and ideal for cleanroom classifications below ISO 5 to optimize vertical laminar flow.

    p - Floor-Mounted Exhaust

    Floor-Mounted Exhausts use side-wall plenums and floor-mounted air handlers to divert air away from the work area. The plenum is mounted directly to the frame and connects to ceiling ducts that exhaust air from the negative pressure room. Floor mount exhausts include internal airflow baffles to smooth corner flow and a pass vent at the bottom with an optional fixed position damper. Containment (negative pressure) rooms require customer furnished in-house exhaust systems capable of pulling the air volume required to create adequate negative pressure

    H4 - Biosafety Levels I & II

    Biosafety Level 1 is specified as work with well-characterized agents that are known to cause disease in healthy, non-immunocompromised adults. Special containment practices and devices are generally not required, but institutional laboratory practices must be implemented to reduce risk to laboratory personnel.

    Biosafety Level 2 is specified as work that poses moderate hazards to personnel and the environment. Research or diagnostic activities that are administered with pathogenic bacteria, such as Staphylococcus aureus or Salmonella, fall into this category. This Biosafety Level builds upon Biosafety Level 1; all of the precautions and practices spelled out in Biosafety Level 1 must be followed in addition to those found in Biosafety Level 2. Special containment practices and devices are generally required to mitigate risk to laboratory personnel.

    I – Upgraded Features
    (back to chart)

    I1 - Ion Bars

    Ionization bars neutralize electrostatic charges, a common requirement for mixing, packaging, or high-speed assembly lines. Static ionizing bars remove errant charges and have special importance for products with insulative properties.

    I2 - Air Curtains

    Air curtains produce a jetstream of ULPA Class 10 micro-filtered air at the entry and exit points of a controlled environment. Air curtains are ideal when doors are frequently opened or for doorless entryways. Operating modes include either motion sensor activation with adjustable delay or continuous operation.

    I3 - Uninterrupted Power Supply

    An uninterrupted power supply (UPS) is only used to maintain power in the cleanroom for a brief time during an unanticipated power outage. A UPS guarantees uninterrupted visibility inside a cleanroom in the event of power loss and provides power for one light (LED or fluorescent) for one hour.

    I4 - Cleanroom Emergency Lights

    The cleanroom emergency light is an LED light with a backup battery that will remain on during a power outage so employees can see well enough to shut down operations, secure any sensitive products, and evacuate safely in the case that power cannot be immediately restored.

    The LED light has a red/green indicator to inform employees after power has returned and the cleanroom is safe to re-enter. When receiving power, the light both operates normally and charges the emergency battery.

    I5 - Germicidal UV Lights

    UV sanitizing modules affix to the cleanroom ceiling grid to neutralize bacteria, viruses, and mold spores. UV light is particularly effective when targeting resistant bacteria, mold/fungal spores, and gram-negative microbes. The UV-C Germicidal Lamps install on a cleanroom ceiling grid for line-of-sight room disinfection. A safety occupancy sensor switches off the UVC lighting to prevent radiation exposure when occupied.

    I6 - Fire Detection System

    Terra provides fire detection and suppression systems ideal for wet benches, exhaust fume lines, and locations involving volatile chemicals. Terra cleanrooms support traditional sprinkler and heat sensor configurations or CO2-based suppression systems. The FS System 7 is an integrated fire detection and CO2 suppression system that includes electro-optical sensors for detecting any type of hydrocarbon or non-hydrocarbon fire, even through gas or vapor. A dual-stage alarm triggers an early warning for fires too small to be sensed by overhead sprinklers. An intelligent multi-stage response system prevents the damaging effects of fire suppression in the case that a small fire self-extinguishes or is suppressed rapidly. Terra engineers work with you to determine the fire suppression system appropriate for your requirements and local fire codes.

    I7 - Fingerprint Scanner

    Biometric fingerprint scanners prevent unauthorized access via shared keys or passwords while also providing data logging capability. An integrated proximity card reader enables two-factor authentication.

    I8 - Iris Scanner

    Fully automated iris scanner for secure, hands-free access (includes data logging and optional secondary keycard reader).

    I9 - Keycard Reader

    Keycard readers provide a durable and economical method for maintaining secured keycard access within a cleanroom facility. The low-profile device reads cards up to 3" away and integrates with access control software for data logging and remote monitoring.

    I10 - Pass Through

    General-Use Pass-Through Chambers are an economical choice for non-sterile items with a low risk of cross-contamination potential including samples, fluids, tools, packaging, or documents.

    ValuLine™ Pass-Through Chambers are configurable with economical black acrylic, chemical resistance polypropylene, or stainless steel for unmatched cleanliness and durability within cleanrooms.

    BioSafe® Pass-Through chambers with continuous seam welds eliminate hard-to-clean cracks and crevices that can harbor particles and germs. CleanSeam™ design conceals the door interlock mechanism behind the chamber’s wall for a completely unobstructed, easy-to-clean chamber interior.

    I11 - Talk Through

    Communication and vocal clarity are critical for successful outcomes within cleanrooms, laboratory, and hospital isolation environments. Mechanical and electronic talkthroughs allow easier communication between internal partitions or outside areas of the cleanroom. Both the mechanical and electronic talk throughs include cleanroom-grade components and are easy to mount in either a stick-built cleanroom wall or Terra hardwall modular cleanroom.

    I12 - Interlocking Doors

    Interlocking doors are common for passthrough chambers and air showers. The interlock prevents doors on either side of the enclosure from opening at the same time. Single side access helps to maintain airflow cascades between rooms of differing pressure and limits room pressure loss after opening and closing of doors.

  3. Terra's BioSafe modular clean rooms meet biopharmaceutical requirements for an ISO 5-8 compliant, sterile processing environment. Designs for single-pass, recirculating, or negative-pressure containment airflow. BioSafe® Cleanroom Features Overview
    Air Flow Design Wall Panel Material Frame Material Standard Components Compatible Cleanroom Class Air Conditioning Environmental Monitoring Ventilation & Contaminate Control Upgraded Features Services

    A - Air Flow Design
    (back to chart)

    A1 - Laminar Flow/Positive Pressure

    Laminar flow air and positive pressure cleanroom design are ideal for non-hazardous, ultra-clean applications. Positive pressure mitigates dirt from entering the cleanroom when opening doors or pass-through chambers. Laminar airflow design ensures that air maintains a singular, uniform direction and velocity from intake to exhaust port. Terra's positive pressure cleanrooms include HEPA filtration systems capable of ISO Class 3 - ISO Class 8 air quality conditions. ULPA filtration units are available for the most sensitive ISO 3 - ISO 5 product applications including pharmaceutical compounding, semiconductor wafer processing, sterile packaging, and micro-nanofabrication.

    A2 - Laminar Flow/Negative Pressure

    A negative pressure laminar flow cleanroom is best suited for hazardous environments. Particularly, when the product is also sensitive or reactive to chemical, environmental, or particulate contamination. Negative pressure cleanrooms prevent the escape of toxic or hazardous air from the containment structure. Laminar airflow design ensures that air flows without interruption between intake and exhaust, which ensures that sterile or biologically sensitive samples remain pure and unadulterated. Terra's negative pressure cleanrooms provide capable and safe production environments for reducing operator hazards in high-risk applications such as USP 800 compounding, infectious disease research, and chemically intensive processes that require volatile chemical handling.

    Terra manufactures and designs cleanrooms to BSL-1 and BSL-2 criteria. Some operations that fall under BSL-2 may require single-pass air that is filtered before being exhausted to the outside; others may allow recirculation of air and release of unfiltered exhaust air.

    A3 - Ventilation/Negative Pressure

    Negative pressure ventilation rooms are designed for handling chemicals that produce toxic, carcinogenic, or noxious vapors. Reverse-flow FFUs capture particles generated in localized cleanroom spaces to minimize contamination and ensure operator protection. Vapor removal FFUs eliminate trace amounts of VOCs from make-up air to prevent chemical fume contamination. Depending on the application, a containment room may require exit filtration: either HEPA/ULPA filters for particles and aerosols and/or carbon filters to remove chemical fumes.

    A4 - Recirculation/Neutral Pressure

    A neutral pressure cleanroom system is designed to ventilate environmental nuisances away from the operator; it is not intended to provide personnel or environmental protection against hazardous substances. In some cases, the environment does not require any specific ISO-rated classification, thus the primary purpose is to isolate particulates and aerosols that would otherwise congregate in adjacent areas or corridors. If it is safe to do so, a recirculating cleanroom allows filtration and reintroduction of room air and reduces heating and energy costs. Neutral pressure is the least energy-intensive when compared to positive and negative pressure designs. Recirculating negative pressure cleanrooms are commonly selected for purity testing, weighing, capsulizing, and packaging pharmaceutical powders.

    A5 - Horizontal Flow/Positive Pressure

    Horizontally configured cleanrooms are advantageous when vertical space and ceiling access is limited or extra tall ceiling requirements. Ceiling height is an important consideration for cleanroom design, especially for large objects found within aerospace, satellite, and telescope manufacturing environments. Horizontal flow cleanrooms introduce air from fan filter units mounted within sidewalls instead of traditional ceiling-mounted blowers. Air moves in parallel with the floor instead of perpendicularly. Air flows from a side-wall integrated with HEPA fan filter units and exits through a parallel wall with an integrated plenum for air return or exhaust. Wall-to-wall laminar airflow is advantageous when handling small parts and liquids which would otherwise be problematic for vertical floor cleanrooms with grated false-flooring.

    B - Wall Panel Material
    (back to chart)

    B1 - Stainless Steel

    Stainless steel is a golden standard among cleanroom construction materials. Easy cleaning, favorable heat properties, and chemical resistance make stainless an ideal choice for biopharmaceutical and semiconductor environments. The smooth surface is easy to wipe down, resists biofilm buildup, and will not off-gas.

    B2 - Powder-Coated Steel

    Powder-coated steel is an economical choice that also provides favorable heat and chemical resistance for most applications. Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

    B3 - Acrylic

    Acrylic is widely used in cleanrooms and other critical environment applications. Its low initial cost, lightweight, transparency, and tensile strength makes it an attractive choice in many situations. Terra offers economical acrylic enclosures as a budget-friendly option. While acrylic is fairly durable against UV light and impact-resistant, the material is easily degraded by alcohols and solvents.

    B4 - Static Dissipative PVC

    Static-Dissipative PVC comes in rigid or flexible material for use on hardwall cleanroom panels or cleanroom curtains, dust covers, microenvironments, and other applications requiring a softer material. Non-dissipative plastics quickly accumulate surface charges that attract contaminants. Dissipative plastics prevent static build-up that attracts airborne particulate and lint fibers, which makes surfaces easier to wipe down. Static-dissipative PVC (SD-PVC) will not hold a static charge, offers wide chemical compatibility, and cleans easily. SD-PVC retains a surface resistivity of 10^6 - 10^8 ohms/square indefinitely unlike spray-on coatings that can wear off after a few years. SD-PVC also resists alcohol and most other sterilizing solutions, thus supporting standard disinfecting procedures and extending the life of your enclosure.

    B5 - Polycarbonate

    Polycarbonate is transparent with a slight gray tint and offers broad-spectrum chemical resistance, high impact resistance, and excellent thermal resistance (to 200°F / 93.3°C). Polycarbonate is stronger and cracks less easily than both acrylic (15x stronger) and glass (250x stronger).

    B6 - Polypropylene

    Polypropylene is an opaque thermoplastic with excellent chemical resistance against acids and solvents.

    B7 - Chlorinated PVC (C-PVC)

    Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels have excellent chemical resistance and prevent particle emission and microbial growth. Their unique solvent-free silicone adhesive allows installation on wallboard substrate creating a strong, rigid structure when mounted to Terra’s steel frame. Welded seams are trim-free, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning.

    B8 - Fiberglass Reinforced Plastic (FRP)

    Class A and C FRP panels feature a unique non-outgassing advanced polymer adhesive for installation on drywall or other substrates. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. A patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

    B9 - Tempered Glass

    Tempered cleanroom glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempered glass is not only impact resistance, but also ideal for its high visual clarity and aesthetic. Glass wall cleanrooms allow easy monitoring of operators and processes within the cleanroom and tend to appear larger and more spacious. Tempered glass is non-outgassing and chemical-resistant, making it ideal for frequent decontamination.

    B10 - Vinyl Curtains

    Cleanroom vinyl curtains are lightweight and rapidly installable for creating room partitions, isolating equipment and processes, or mobile isolation when configured with wheel casters. Curtain strips are available in either 4' -wide softwall panels made of blur-free 40 mil vinyl or 8” -wide strip curtains made of blur-free 60 mil vinyl. Static-Dissipative PVC vinyl includes built-in static inhibitors and is recommended for all cleanrooms to minimize particle cling. A T-Grid Mounting System allows suspension of curtains or strip shields from Terra's cleanroom ceiling grid.

    B11 - Modesty Panels

    Modesty panels provide the combined benefits of natural light while also maintaining a degree of privacy. These panels are ideal for multi-level cleanroom mezzanines that require additional office space or unclassified storage. Modesty panels include an opaque lower panel and upper panel of transparent glass or cleanroom-rated plastic such as polycarbonate or static dissipative PVC. A solid lower panel provides a balance of privacy while the transparent window allows the introduction of natural light and tends to make the space appear larger and less constricted.

    B12 - Insulated Panels

    A double-wall, insulated wall panel promotes a stable environment for long-term sample storage, cell cultivation, or high-volume process equipment. Terra's double-wall insulated panels are adaptable to the customer’s temperature range specifications and application requirements including cold rooms, incubation, and sound isolation. Double-wall construction with 1”-thick polyurethane insulation enhances cleanroom heating/cooling efficiency and thermal stability. Rigid foam insulation paired with a climate control system provides better temperature stability for applications that require raised flooring for true laminar flow. Double-wall structure allows air to circulate through the inter-wall plenum which further increases filtration and A/C efficiency in high-performance applications.

    B13 - Center-Mount Panels With Mirror-Finish Steel Brackets

    Most of Terra’s competitors affix the cleanroom wall panels directly to the frame (mounted on the internal or external side of the frame. With this design, replacing cleanroom wall panels is a cumbersome task and requires cleanroom shutdown. If the panels are affixed externally to the frame, installing coved flooring is virtually impossible and the customers are tasked with sterilizing the frame along with all of its crevices. If the panels are mounted internally, the customer loses precious cleanroom space. If the flooring is coved to the internal panels, the customer loses even more space. Terra’s center-mount panel design alleviates these issues.

    C - Frame Material
    (back to chart)

    C1 - Stainless Steel (<20% or -5" Hg)

    Unlike most competitors who offer only aluminum extruded frames, Terra Universal provides steel and stainless steel frame materials that maintain structural integrity far longer than aluminum under fire conditions. Terra Universal’s BioSafe stainless steel cleanrooms may be ideal for sterile applications since they are not affected by harsh wash-down chemicals.

    Double-Wall Steel Panels
    Double-wall panels, available in 304/316 stainless or powder-coated steel, create a freestanding structure for affixing a ceiling grid. Each panel consists of an inside and outside portion, which are joined by a compression ball-and-socket fastener. Once joined, the walls can be detached by means of magnetic-grip handles (not included). The hollow space created by these panels provides a convenient installation zone for electrical conduit, gas, and vacuum service line enhancing systems, cleanliness, and appearance. In controlled temperature applications, this void may be insulated to optimize thermal stability and reduce energy costs.

    All Steel BioSafe Cleanrooms
    Terra’s all-steel BioSafe® Modular Cleanroom creates a rigid, self-supporting structure without a separate frame or external bracing, a key advantage over other designs that require special permitting and contractor installation.

    316L Stainless steel contains the same corrosion-resistant materials as 316 but includes the added benefit of lower carbon content—eliminating the opportunity for excessive metallic contamination and making cracking less likely. Both 316 and 316L can withstand chlorides and chlorinated solutions, such as Spor-Klenz® and Isopropyl Acetate.

    C2 - Powder-Coated Steel

    Terra's powder-coated steel cleanroom frames support free-standing softwall spans of up to 20 feet without internal posts or ceiling suspension cables. If necessary, reinforcements are provided for high-clearance, long-span rooms. Reinforcements ensure stability and additional seismic requirements for particle-sensitive samples and analytical instruments.

    • Excellent for cleanroom applications
    • Good weather resistance
    • Good mechanical properties
    • Good chemical resistance
    • Excellent UV protection
    • Good storage stability
    • Underwriter Laboratories recognized component (UL approved)

    D – Standard Components
    (back to chart)

    D1 - Filter Fan Units (FFUs)

    Terra’s WhisperFlow® FFU’s feature UL-listed components and built-in baffles that quietly produce uniform laminar airflow across the face of the filter. UL-listed products meet the highest manufacturing standards and reduce the risk of damage, injuries, and electrical hazards.

    Smart® Fan Filter Units with EC Motors provide annual energy savings of nearly $500 per fan filter unit. The control card features industry-standard MODBUS® networking, precision speed control (1-100%), and closed-loop control capability for air pressure, airflow, and particle count sensors.

    Terra fan filter unit housings are configurable for room-side replaceable, explosion-proof, heated, and low-profile configurations. The same high performance fan filter units are found throughout Terra products including cleanrooms, laminar flow hoods, and containment systems. Filter fan units are stocked, pre-tested, crated, and ready for immediate shipment from Terra's distribution centers.

    D2 - LED Lights

    Terra's LED flat panel troffer lights include dimmable brightness and 5 selectable color temperatures to achieve the perfect balance of light including 3000K / 3500K / 4000K / 5000K / 6500K. When paired with Terra's cleanroom control panels, lighting control is available from a centralized location out of the cleanroom. Terra's power distribution modules (PDMs) allow connection of lighting and fan filter via quick connections that do not require hardwiring. LED panels are available with integrated backup batteries that allow for up to an hour of continued visibility in the case of a power failure.

    D3 - Control Panels

    Cleanroom Control Panels centralize control of cleanroom lighting, power, fan speed, and assignable groups.

    Standard Control Panels provide central control and connection of lights and filters. A Fan Filter Replacement Alarm provides a reliable, quantitative method for determining when a HEPA filter requires replacement. An optional Night Service Switch drops all Fan/Filter Units (FFUs) into a low-energy mode for nights and weekends.

    Smart® Control Panels connect to EC FFUs for individual or grouped fan control and remote monitoring of room differential pressure, particle counts, temperature, and humidity. Robust systems offer advanced control for up to 200 fan filter units and 16 independently controlled rooms.

    D4 - Power Distribution Modules (PDMs)

    PDMs allow the addition of ceiling fan/filter units and lights to meet any cleanliness requirement or to upgrade ISO levels or lighting levels after installation. Terra’s PDMs use 3-pin or 4-pin quick connect fittings to power all FFUs, and lights, no matter the cleanroom size. Hardwiring is only required to connect the Primary, Secondary, Booster, and Duplex PDM modules. Because no additional hard wiring is required to connect and disconnect power to additional lights and fan filters, contractors save time, money, and resources during cleanroom installation, expansion, or modification.

    D5 - Doors

    Standard doors with aluminum frames are available in either single or double door configurations and a choice of acrylic or static-dissipative PVC panels.

    Swing doors are either Left Hand Reverse (LHR) or Right Hand Reverse (RHR) when viewed from outside the cleanroom (dirty side) to minimize particulate impact on the cleanroom when the door opens.

    Cleanroom doors on prehung frames install easily for negative or positive pressure cleanrooms. Choose from swing-out or sliding doors that are UL leak-rated and suitable for ISO 4 - ISO 8 environments.

    BioSafe® 316L stainless steel doors have continuous seam welds for sterile and aseptic environments. Terra's BioSafe products forgo cracks and crevices known to harbor particles and microbes. Dual-pane, flush-mount windows minimize horizontal surfaces and crevices where contaminants collect.

    Fire-rated doors include insulated double stainless steel walls, wire-free construction, and a fire-rated glass-ceramic viewing window that is impact resistant.

    D6 - Windows

    Terra's cleanroom windows are compatible with any cleanroom wall material or thickness and designed for compliance within healthcare, pharmaceutical, and GMP manufacturing applications. These easy-to-clean, hygienic windows enhance the visibility of operations and foot traffic without jeopardizing GMP design standards.

Developed specifically for aseptic requirements in bio-pharmaceutical and cGMP cleanrooms, these hygienic cleanroom windows bring more light and visibility to your workspace without compromising cleanliness requirements. Choose from easy-to-clean framed or frameless stainless steel designs. Fire-rated cleanroom window designs meet building code requirements to protect your employees, operations, and business.

    D7 - Filter Replacement Alarm System

    Fan filter replacement alarms provide automatic replacement alerts to avoid costly and unexpected operational interruptions. Alarms trigger an audible buzzer when differential pressure reaches an adjustable setpoint. Alarms provide a reliable method for establishing fan filter replacement intervals while also reducing the risk of electrical/fire hazards caused by overworked motors pushing against overloaded HEPA filters.

    BioSafe® cleanroom windows include compression fittings for fast, hardware-free installation. Framed and frameless designs are compliant with BSL-rated rooms and ISO 4-compliant spaces.

    E – Compatible Cleanroom Class
    (back to chart)

    ISO 14644-1 is a document issued by the International Standards Organization which classifies a controlled environment into six categories of air cleanliness. ISO 14644-1 supersedes previous standards for cleanroom testing and validation such as Federal Standard 209E (FS209E). While references to FS209E are still used, ISO 14644-1 is internationally endorsed for testing and validating a cleanroom that meets FDA, USP, GMP, CGMP, or EU standards. An ISO 14644-1 cleanroom is classified on a scale between ISO Class 3 to ISO Class 8. The ISO class for a particular room is determined for the entire room and not for individual components or materials.

    Terra hardwall and BioSafe cleanrooms are configurable for the cleanest ISO 3 - 5 applications including wafer fabrication, microelectronics, nanotechnology, and sterile or biologically sensitive processes. Most industries fall within ISO 6 - ISO 8 cleanroom requirements including medical devices, general manufacturing, electronics assembly, food/beverage, and particulate or aerosol enclosures. Terra's modular hardwall configurations are available in steel, stainless steel, and plastic panels for ISO 5 - ISO 8 spaces with precise particulate and climate control requirements. ValuLine Softwall Modular Cleanrooms configurations are economical for less intensive or non-classified environments and available with preconfigured and ready-to-ship options.

    F – Air Conditioning
    (back to chart)

    F1 - Temperature

    Terra will work with a local HVAC contractor to provide an air control system that meets your cooling requirements and local codes. If the existing HVAC system cannot be used, Terra will provide the ducting and recirculation system that routes exhaust air to the compressor and delivers cool air to the ceiling FFUs in ample volume to maintain the desired air velocity inside the enclosure. Additional Cleanroom A/C Module provides economical cooling in facilities without adequate HVAC. Based on the cleanroom size, desired temperature, and heat dissipated inside the cleanroom, Terra will configure the appropriate number of AC units required for the space. With larger cleanrooms, Terra works with a local contractor to install a split A/C system, which moves the heat-generating compressor outside the building to reduce heat loads inside the facility.

    F2 - Humidification

    Terra’s Ultrasonic Humidifier is designed to be a turnkey system as an addition to your cleanroom. Simply place and rest the unit on an open 2’x4’ ceiling grid from above the cleanroom. No fasteners or gaskets are required to secure the unit in place. The system uses five ultrasonic transducers to generate mist and operates on only 150W, less power than conventional steam canister humidifiers. Humidification and dehumidification modules are controlled by a humidistat independent of the thermostat. The Ultrasonic Humidifier comes with a remote control to turn on the unit and set your desired RH levels (up to 100% RH).

    F3 - Dehumidification

    Cleanroom Dehumidification Modules use silica gel desiccant housed in a rotor to produce dry airflow.

    F4 - AC Module Interface

    Air Conditioning Modules provide economical cooling in facilities without adequate HVAC. Air Conditioning Modules incorporate dehumidification circuitry and are controlled by a humidistat independent of the thermostat. The unit includes a powder-coated steel air distribution plenum mounted to the external cleanroom wall, which provides conditioned air to up to six FFUs.

    Terra can provide custom HVAC modules that operate similarly to an environmental test chamber, adjusting the supply air's temperature and humidity to maintain specific conditions within tight tolerances. This type of system is particularly useful when the environment immediately outside of the cleanroom experiences significant fluctuations in temperature or relative humidity.

    G – Environmental Monitoring
    (back to chart)

    Smart® Fan Filter Power & Control Panels centralize control over assignable groups or specific targets when conducting cleanroom pressure-balancing, troubleshooting, or maintenance. An upgraded Smart Control System allows additional environmental sensors and FFU control to meet critical performance/monitoring requirements. A control panel assembly includes power controls for the Fan/Filter Units, lights, and is configurable for other integrations including temperature, humidity, particle counts, differential pressure, and air velocity sensors.

    G1 - Temperature

    Terra's thermometers, hygrometers, and data recording instruments help monitor, control, and document environmental conditions in your cleanroom or laboratory. Temperature, dew point, and humidity monitoring are essential for products with known sensitivities to heat, environmental drift, static, or trace moisture. Terra Universal provides decades of field-proven expertise and a wide selection of thermometers and sensors for complete room monitoring.

    G2 - Humidity

    Many labs and cleanrooms choose to maintain a 30% RH level. Anything more than that may cause other issues, such as damage to moisture-sensitive materials. Every Terra cleanroom is available with integrated sensors and monitoring equipment for measuring and recording relative humidity values within the cleanroom.

    G3 - Differential Pressure

    Magnehelic® Differential Pressure Gauges monitor room-to-room pressure or filter back-pressure. Digital and alarm models are available for activating alerts when pressures fall out of specification.

    G4 - Particle Counting

    Particle counters are available as standalone handheld units for spot-checking and validation, or as built-in modules for remote monitoring after connection to a centralized building management system (BMS) such as MODBUS.

    H – Ventilation & Contaminate Control
    (back to chart)

    H1 - False Ceiling Exhaust

    False Ceiling Exhaust: Use of a plenum mounted above the drop ceiling to divert air away from the work area. A false ceiling exhaust includes an array of ceiling-mounted reverse flow fan filter units. Reverse fan filter designs remove air from the work environment and port to an outside environment or dedicated HVAC exhaust. Reverse flow fan filter units mount to the ceiling grid and are available with integrated blowers, or with motorless designs for connection to a remote HVAC blower.

    H2 - False Floor Exhaust (Complete Laminarity)

    False Floor Exhaust: Raised grated or air-permeable flooring with bottom plenum underneath to achieve full airflow laminarity. False floor exhaust systems, also known as pass through floor exhausts, feature a grated flooring that provides unidirectional airflow and passage of contaminated air. Raised flooring is common for semiconductor applications and ideal for cleanroom classifications below ISO 5 to optimize vertical laminar flow.

    p - Floor-Mounted Exhaust

    Floor-Mounted Exhausts use side-wall plenums and floor-mounted air handlers to divert air away from the work area. The plenum is mounted directly to the frame and connects to ceiling ducts that exhaust air from the negative pressure room. Floor mount exhausts include internal airflow baffles to smooth corner flow and a pass vent at the bottom with an optional fixed position damper. Containment (negative pressure) rooms require customer furnished in-house exhaust systems capable of pulling the air volume required to create adequate negative pressure

    H4 - Biosafety Levels I & II

    Biosafety Level 1 is specified as work with well-characterized agents that are known to cause disease in healthy, non-immunocompromised adults. Special containment practices and devices are generally not required, but institutional laboratory practices must be implemented to reduce risk to laboratory personnel.

    Biosafety Level 2 is specified as work that poses moderate hazards to personnel and the environment. Research or diagnostic activities that are administered with pathogenic bacteria, such as Staphylococcus aureus or Salmonella, fall into this category. This Biosafety Level builds upon Biosafety Level 1; all of the precautions and practices spelled out in Biosafety Level 1 must be followed in addition to those found in Biosafety Level 2. Special containment practices and devices are generally required to mitigate risk to laboratory personnel.

    I – Upgraded Features
    (back to chart)

    I1 - Ion Bars

    Ionization bars neutralize electrostatic charges, a common requirement for mixing, packaging, or high-speed assembly lines. Static ionizing bars remove errant charges and have special importance for products with insulative properties.

    I2 - Air Curtains

    Air curtains produce a jetstream of ULPA Class 10 micro-filtered air at the entry and exit points of a controlled environment. Air curtains are ideal when doors are frequently opened or for doorless entryways. Operating modes include either motion sensor activation with adjustable delay or continuous operation.

    I3 - Uninterrupted Power Supply

    An uninterrupted power supply (UPS) is only used to maintain power in the cleanroom for a brief time during an unanticipated power outage. A UPS guarantees uninterrupted visibility inside a cleanroom in the event of power loss and provides power for one light (LED or fluorescent) for one hour.

    I4 - Cleanroom Emergency Lights

    The cleanroom emergency light is an LED light with a backup battery that will remain on during a power outage so employees can see well enough to shut down operations, secure any sensitive products, and evacuate safely in the case that power cannot be immediately restored.

    The LED light has a red/green indicator to inform employees after power has returned and the cleanroom is safe to re-enter. When receiving power, the light both operates normally and charges the emergency battery.

    I5 - Germicidal UV Lights

    UV sanitizing modules affix to the cleanroom ceiling grid to neutralize bacteria, viruses, and mold spores. UV light is particularly effective when targeting resistant bacteria, mold/fungal spores, and gram-negative microbes. The UV-C Germicidal Lamps install on a cleanroom ceiling grid for line-of-sight room disinfection. A safety occupancy sensor switches off the UVC lighting to prevent radiation exposure when occupied.

    I6 - Fire Detection System

    Terra provides fire detection and suppression systems ideal for wet benches, exhaust fume lines, and locations involving volatile chemicals. Terra cleanrooms support traditional sprinkler and heat sensor configurations or CO2-based suppression systems. The FS System 7 is an integrated fire detection and CO2 suppression system that includes electro-optical sensors for detecting any type of hydrocarbon or non-hydrocarbon fire, even through gas or vapor. A dual-stage alarm triggers an early warning for fires too small to be sensed by overhead sprinklers. An intelligent multi-stage response system prevents the damaging effects of fire suppression in the case that a small fire self-extinguishes or is suppressed rapidly. Terra engineers work with you to determine the fire suppression system appropriate for your requirements and local fire codes.

    I7 - Fingerprint Scanner

    Biometric fingerprint scanners prevent unauthorized access via shared keys or passwords while also providing data logging capability. An integrated proximity card reader enables two-factor authentication.

    I8 - Iris Scanner

    Fully automated iris scanner for secure, hands-free access (includes data logging and optional secondary keycard reader).

    I9 - Keycard Reader

    Keycard readers provide a durable and economical method for maintaining secured keycard access within a cleanroom facility. The low-profile device reads cards up to 3" away and integrates with access control software for data logging and remote monitoring.

    I10 - Pass Through

    General-Use Pass-Through Chambers are an economical choice for non-sterile items with a low risk of cross-contamination potential including samples, fluids, tools, packaging, or documents.

    ValuLine™ Pass-Through Chambers are configurable with economical black acrylic, chemical resistance polypropylene, or stainless steel for unmatched cleanliness and durability within cleanrooms.

    BioSafe® Pass-Through chambers with continuous seam welds eliminate hard-to-clean cracks and crevices that can harbor particles and germs. CleanSeam™ design conceals the door interlock mechanism behind the chamber’s wall for a completely unobstructed, easy-to-clean chamber interior.

    I11 - Talk Through

    Communication and vocal clarity are critical for successful outcomes within cleanrooms, laboratory, and hospital isolation environments. Mechanical and electronic talkthroughs allow easier communication between internal partitions or outside areas of the cleanroom. Both the mechanical and electronic talk throughs include cleanroom-grade components and are easy to mount in either a stick-built cleanroom wall or Terra hardwall modular cleanroom.

    I12 - Interlocking Doors

    Interlocking doors are common for passthrough chambers and air showers. The interlock prevents doors on either side of the enclosure from opening at the same time. Single side access helps to maintain airflow cascades between rooms of differing pressure and limits room pressure loss after opening and closing of doors.

    Air Flow Design Wall Panel Material Frame Material Standard Components Compatible Cleanroom Class Air Conditioning Environmental Monitoring Ventilation & Contaminate Control Upgraded Features Services

    A - Air Flow Design
    (back to chart)

    A1 - Laminar Flow/Positive Pressure

    Laminar flow air and positive pressure cleanroom design are ideal for non-hazardous, ultra-clean applications. Positive pressure mitigates dirt from entering the cleanroom when opening doors or pass-through chambers. Laminar airflow design ensures that air maintains a singular, uniform direction and velocity from intake to exhaust port. Terra's positive pressure cleanrooms include HEPA filtration systems capable of ISO Class 3 - ISO Class 8 air quality conditions. ULPA filtration units are available for the most sensitive ISO 3 - ISO 5 product applications including pharmaceutical compounding, semiconductor wafer processing, sterile packaging, and micro-nanofabrication.

    A2 - Laminar Flow/Negative Pressure

    A negative pressure laminar flow cleanroom is best suited for hazardous environments. Particularly, when the product is also sensitive or reactive to chemical, environmental, or particulate contamination. Negative pressure cleanrooms prevent the escape of toxic or hazardous air from the containment structure. Laminar airflow design ensures that air flows without interruption between intake and exhaust, which ensures that sterile or biologically sensitive samples remain pure and unadulterated. Terra's negative pressure cleanrooms provide capable and safe production environments for reducing operator hazards in high-risk applications such as USP 800 compounding, infectious disease research, and chemically intensive processes that require volatile chemical handling.

    Terra manufactures and designs cleanrooms to BSL-1 and BSL-2 criteria. Some operations that fall under BSL-2 may require single-pass air that is filtered before being exhausted to the outside; others may allow recirculation of air and release of unfiltered exhaust air.

    A3 - Ventilation/Negative Pressure

    Negative pressure ventilation rooms are designed for handling chemicals that produce toxic, carcinogenic, or noxious vapors. Reverse-flow FFUs capture particles generated in localized cleanroom spaces to minimize contamination and ensure operator protection. Vapor removal FFUs eliminate trace amounts of VOCs from make-up air to prevent chemical fume contamination. Depending on the application, a containment room may require exit filtration: either HEPA/ULPA filters for particles and aerosols and/or carbon filters to remove chemical fumes.

    A4 - Recirculation/Neutral Pressure

    A neutral pressure cleanroom system is designed to ventilate environmental nuisances away from the operator; it is not intended to provide personnel or environmental protection against hazardous substances. In some cases, the environment does not require any specific ISO-rated classification, thus the primary purpose is to isolate particulates and aerosols that would otherwise congregate in adjacent areas or corridors. If it is safe to do so, a recirculating cleanroom allows filtration and reintroduction of room air and reduces heating and energy costs. Neutral pressure is the least energy-intensive when compared to positive and negative pressure designs. Recirculating negative pressure cleanrooms are commonly selected for purity testing, weighing, capsulizing, and packaging pharmaceutical powders.

    A5 - Horizontal Flow/Positive Pressure

    Horizontally configured cleanrooms are advantageous when vertical space and ceiling access is limited or extra tall ceiling requirements. Ceiling height is an important consideration for cleanroom design, especially for large objects found within aerospace, satellite, and telescope manufacturing environments. Horizontal flow cleanrooms introduce air from fan filter units mounted within sidewalls instead of traditional ceiling-mounted blowers. Air moves in parallel with the floor instead of perpendicularly. Air flows from a side-wall integrated with HEPA fan filter units and exits through a parallel wall with an integrated plenum for air return or exhaust. Wall-to-wall laminar airflow is advantageous when handling small parts and liquids which would otherwise be problematic for vertical floor cleanrooms with grated false-flooring.

    B - Wall Panel Material
    (back to chart)

    B1 - Stainless Steel

    Stainless steel is a golden standard among cleanroom construction materials. Easy cleaning, favorable heat properties, and chemical resistance make stainless an ideal choice for biopharmaceutical and semiconductor environments. The smooth surface is easy to wipe down, resists biofilm buildup, and will not off-gas.

    B2 - Powder-Coated Steel

    Powder-coated steel is an economical choice that also provides favorable heat and chemical resistance for most applications. Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

    B3 - Acrylic

    Acrylic is widely used in cleanrooms and other critical environment applications. Its low initial cost, lightweight, transparency, and tensile strength makes it an attractive choice in many situations. Terra offers economical acrylic enclosures as a budget-friendly option. While acrylic is fairly durable against UV light and impact-resistant, the material is easily degraded by alcohols and solvents.

    B4 - Static Dissipative PVC

    Static-Dissipative PVC comes in rigid or flexible material for use on hardwall cleanroom panels or cleanroom curtains, dust covers, microenvironments, and other applications requiring a softer material. Non-dissipative plastics quickly accumulate surface charges that attract contaminants. Dissipative plastics prevent static build-up that attracts airborne particulate and lint fibers, which makes surfaces easier to wipe down. Static-dissipative PVC (SD-PVC) will not hold a static charge, offers wide chemical compatibility, and cleans easily. SD-PVC retains a surface resistivity of 10^6 - 10^8 ohms/square indefinitely unlike spray-on coatings that can wear off after a few years. SD-PVC also resists alcohol and most other sterilizing solutions, thus supporting standard disinfecting procedures and extending the life of your enclosure.

    B5 - Polycarbonate

    Polycarbonate is transparent with a slight gray tint and offers broad-spectrum chemical resistance, high impact resistance, and excellent thermal resistance (to 200°F / 93.3°C). Polycarbonate is stronger and cracks less easily than both acrylic (15x stronger) and glass (250x stronger).

    B6 - Polypropylene

    Polypropylene is an opaque thermoplastic with excellent chemical resistance against acids and solvents.

    B7 - Chlorinated PVC (C-PVC)

    Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels have excellent chemical resistance and prevent particle emission and microbial growth. Their unique solvent-free silicone adhesive allows installation on wallboard substrate creating a strong, rigid structure when mounted to Terra’s steel frame. Welded seams are trim-free, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning.

    B8 - Fiberglass Reinforced Plastic (FRP)

    Class A and C FRP panels feature a unique non-outgassing advanced polymer adhesive for installation on drywall or other substrates. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. A patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

    B9 - Tempered Glass

    Tempered cleanroom glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempered glass is not only impact resistance, but also ideal for its high visual clarity and aesthetic. Glass wall cleanrooms allow easy monitoring of operators and processes within the cleanroom and tend to appear larger and more spacious. Tempered glass is non-outgassing and chemical-resistant, making it ideal for frequent decontamination.

    B10 - Vinyl Curtains

    Cleanroom vinyl curtains are lightweight and rapidly installable for creating room partitions, isolating equipment and processes, or mobile isolation when configured with wheel casters. Curtain strips are available in either 4' -wide softwall panels made of blur-free 40 mil vinyl or 8” -wide strip curtains made of blur-free 60 mil vinyl. Static-Dissipative PVC vinyl includes built-in static inhibitors and is recommended for all cleanrooms to minimize particle cling. A T-Grid Mounting System allows suspension of curtains or strip shields from Terra's cleanroom ceiling grid.

    B11 - Modesty Panels

    Modesty panels provide the combined benefits of natural light while also maintaining a degree of privacy. These panels are ideal for multi-level cleanroom mezzanines that require additional office space or unclassified storage. Modesty panels include an opaque lower panel and upper panel of transparent glass or cleanroom-rated plastic such as polycarbonate or static dissipative PVC. A solid lower panel provides a balance of privacy while the transparent window allows the introduction of natural light and tends to make the space appear larger and less constricted.

    B12 - Insulated Panels

    A double-wall, insulated wall panel promotes a stable environment for long-term sample storage, cell cultivation, or high-volume process equipment. Terra's double-wall insulated panels are adaptable to the customer’s temperature range specifications and application requirements including cold rooms, incubation, and sound isolation. Double-wall construction with 1”-thick polyurethane insulation enhances cleanroom heating/cooling efficiency and thermal stability. Rigid foam insulation paired with a climate control system provides better temperature stability for applications that require raised flooring for true laminar flow. Double-wall structure allows air to circulate through the inter-wall plenum which further increases filtration and A/C efficiency in high-performance applications.

    B13 - Center-Mount Panels With Mirror-Finish Steel Brackets

    Most of Terra’s competitors affix the cleanroom wall panels directly to the frame (mounted on the internal or external side of the frame. With this design, replacing cleanroom wall panels is a cumbersome task and requires cleanroom shutdown. If the panels are affixed externally to the frame, installing coved flooring is virtually impossible and the customers are tasked with sterilizing the frame along with all of its crevices. If the panels are mounted internally, the customer loses precious cleanroom space. If the flooring is coved to the internal panels, the customer loses even more space. Terra’s center-mount panel design alleviates these issues.

    C - Frame Material
    (back to chart)

    C1 - Stainless Steel (<20% or -5" Hg)

    Unlike most competitors who offer only aluminum extruded frames, Terra Universal provides steel and stainless steel frame materials that maintain structural integrity far longer than aluminum under fire conditions. Terra Universal’s BioSafe stainless steel cleanrooms may be ideal for sterile applications since they are not affected by harsh wash-down chemicals.

    Double-Wall Steel Panels
    Double-wall panels, available in 304/316 stainless or powder-coated steel, create a freestanding structure for affixing a ceiling grid. Each panel consists of an inside and outside portion, which are joined by a compression ball-and-socket fastener. Once joined, the walls can be detached by means of magnetic-grip handles (not included). The hollow space created by these panels provides a convenient installation zone for electrical conduit, gas, and vacuum service line enhancing systems, cleanliness, and appearance. In controlled temperature applications, this void may be insulated to optimize thermal stability and reduce energy costs.

    All Steel BioSafe Cleanrooms
    Terra’s all-steel BioSafe® Modular Cleanroom creates a rigid, self-supporting structure without a separate frame or external bracing, a key advantage over other designs that require special permitting and contractor installation.

    316L Stainless steel contains the same corrosion-resistant materials as 316 but includes the added benefit of lower carbon content—eliminating the opportunity for excessive metallic contamination and making cracking less likely. Both 316 and 316L can withstand chlorides and chlorinated solutions, such as Spor-Klenz® and Isopropyl Acetate.

    C2 - Powder-Coated Steel

    Terra's powder-coated steel cleanroom frames support free-standing softwall spans of up to 20 feet without internal posts or ceiling suspension cables. If necessary, reinforcements are provided for high-clearance, long-span rooms. Reinforcements ensure stability and additional seismic requirements for particle-sensitive samples and analytical instruments.

    • Excellent for cleanroom applications
    • Good weather resistance
    • Good mechanical properties
    • Good chemical resistance
    • Excellent UV protection
    • Good storage stability
    • Underwriter Laboratories recognized component (UL approved)

    D – Standard Components
    (back to chart)

    D1 - Filter Fan Units (FFUs)

    Terra’s WhisperFlow® FFU’s feature UL-listed components and built-in baffles that quietly produce uniform laminar airflow across the face of the filter. UL-listed products meet the highest manufacturing standards and reduce the risk of damage, injuries, and electrical hazards.

    Smart® Fan Filter Units with EC Motors provide annual energy savings of nearly $500 per fan filter unit. The control card features industry-standard MODBUS® networking, precision speed control (1-100%), and closed-loop control capability for air pressure, airflow, and particle count sensors.

    Terra fan filter unit housings are configurable for room-side replaceable, explosion-proof, heated, and low-profile configurations. The same high performance fan filter units are found throughout Terra products including cleanrooms, laminar flow hoods, and containment systems. Filter fan units are stocked, pre-tested, crated, and ready for immediate shipment from Terra's distribution centers.

    D2 - LED Lights

    Terra's LED flat panel troffer lights include dimmable brightness and 5 selectable color temperatures to achieve the perfect balance of light including 3000K / 3500K / 4000K / 5000K / 6500K. When paired with Terra's cleanroom control panels, lighting control is available from a centralized location out of the cleanroom. Terra's power distribution modules (PDMs) allow connection of lighting and fan filter via quick connections that do not require hardwiring. LED panels are available with integrated backup batteries that allow for up to an hour of continued visibility in the case of a power failure.

    D3 - Control Panels

    Cleanroom Control Panels centralize control of cleanroom lighting, power, fan speed, and assignable groups.

    Standard Control Panels provide central control and connection of lights and filters. A Fan Filter Replacement Alarm provides a reliable, quantitative method for determining when a HEPA filter requires replacement. An optional Night Service Switch drops all Fan/Filter Units (FFUs) into a low-energy mode for nights and weekends.

    Smart® Control Panels connect to EC FFUs for individual or grouped fan control and remote monitoring of room differential pressure, particle counts, temperature, and humidity. Robust systems offer advanced control for up to 200 fan filter units and 16 independently controlled rooms.

    D4 - Power Distribution Modules (PDMs)

    PDMs allow the addition of ceiling fan/filter units and lights to meet any cleanliness requirement or to upgrade ISO levels or lighting levels after installation. Terra’s PDMs use 3-pin or 4-pin quick connect fittings to power all FFUs, and lights, no matter the cleanroom size. Hardwiring is only required to connect the Primary, Secondary, Booster, and Duplex PDM modules. Because no additional hard wiring is required to connect and disconnect power to additional lights and fan filters, contractors save time, money, and resources during cleanroom installation, expansion, or modification.

    D5 - Doors

    Standard doors with aluminum frames are available in either single or double door configurations and a choice of acrylic or static-dissipative PVC panels.

    Swing doors are either Left Hand Reverse (LHR) or Right Hand Reverse (RHR) when viewed from outside the cleanroom (dirty side) to minimize particulate impact on the cleanroom when the door opens.

    Cleanroom doors on prehung frames install easily for negative or positive pressure cleanrooms. Choose from swing-out or sliding doors that are UL leak-rated and suitable for ISO 4 - ISO 8 environments.

    BioSafe® 316L stainless steel doors have continuous seam welds for sterile and aseptic environments. Terra's BioSafe products forgo cracks and crevices known to harbor particles and microbes. Dual-pane, flush-mount windows minimize horizontal surfaces and crevices where contaminants collect.

    Fire-rated doors include insulated double stainless steel walls, wire-free construction, and a fire-rated glass-ceramic viewing window that is impact resistant.

    D6 - Windows

    Terra's cleanroom windows are compatible with any cleanroom wall material or thickness and designed for compliance within healthcare, pharmaceutical, and GMP manufacturing applications. These easy-to-clean, hygienic windows enhance the visibility of operations and foot traffic without jeopardizing GMP design standards.

Developed specifically for aseptic requirements in bio-pharmaceutical and cGMP cleanrooms, these hygienic cleanroom windows bring more light and visibility to your workspace without compromising cleanliness requirements. Choose from easy-to-clean framed or frameless stainless steel designs. Fire-rated cleanroom window designs meet building code requirements to protect your employees, operations, and business.

    D7 - Filter Replacement Alarm System

    Fan filter replacement alarms provide automatic replacement alerts to avoid costly and unexpected operational interruptions. Alarms trigger an audible buzzer when differential pressure reaches an adjustable setpoint. Alarms provide a reliable method for establishing fan filter replacement intervals while also reducing the risk of electrical/fire hazards caused by overworked motors pushing against overloaded HEPA filters.

    BioSafe® cleanroom windows include compression fittings for fast, hardware-free installation. Framed and frameless designs are compliant with BSL-rated rooms and ISO 4-compliant spaces.

    E – Compatible Cleanroom Class
    (back to chart)

    ISO 14644-1 is a document issued by the International Standards Organization which classifies a controlled environment into six categories of air cleanliness. ISO 14644-1 supersedes previous standards for cleanroom testing and validation such as Federal Standard 209E (FS209E). While references to FS209E are still used, ISO 14644-1 is internationally endorsed for testing and validating a cleanroom that meets FDA, USP, GMP, CGMP, or EU standards. An ISO 14644-1 cleanroom is classified on a scale between ISO Class 3 to ISO Class 8. The ISO class for a particular room is determined for the entire room and not for individual components or materials.

    Terra hardwall and BioSafe cleanrooms are configurable for the cleanest ISO 3 - 5 applications including wafer fabrication, microelectronics, nanotechnology, and sterile or biologically sensitive processes. Most industries fall within ISO 6 - ISO 8 cleanroom requirements including medical devices, general manufacturing, electronics assembly, food/beverage, and particulate or aerosol enclosures. Terra's modular hardwall configurations are available in steel, stainless steel, and plastic panels for ISO 5 - ISO 8 spaces with precise particulate and climate control requirements. ValuLine Softwall Modular Cleanrooms configurations are economical for less intensive or non-classified environments and available with preconfigured and ready-to-ship options.

    F – Air Conditioning
    (back to chart)

    F1 - Temperature

    Terra will work with a local HVAC contractor to provide an air control system that meets your cooling requirements and local codes. If the existing HVAC system cannot be used, Terra will provide the ducting and recirculation system that routes exhaust air to the compressor and delivers cool air to the ceiling FFUs in ample volume to maintain the desired air velocity inside the enclosure. Additional Cleanroom A/C Module provides economical cooling in facilities without adequate HVAC. Based on the cleanroom size, desired temperature, and heat dissipated inside the cleanroom, Terra will configure the appropriate number of AC units required for the space. With larger cleanrooms, Terra works with a local contractor to install a split A/C system, which moves the heat-generating compressor outside the building to reduce heat loads inside the facility.

    F2 - Humidification

    Terra’s Ultrasonic Humidifier is designed to be a turnkey system as an addition to your cleanroom. Simply place and rest the unit on an open 2’x4’ ceiling grid from above the cleanroom. No fasteners or gaskets are required to secure the unit in place. The system uses five ultrasonic transducers to generate mist and operates on only 150W, less power than conventional steam canister humidifiers. Humidification and dehumidification modules are controlled by a humidistat independent of the thermostat. The Ultrasonic Humidifier comes with a remote control to turn on the unit and set your desired RH levels (up to 100% RH).

    F3 - Dehumidification

    Cleanroom Dehumidification Modules use silica gel desiccant housed in a rotor to produce dry airflow.

    F4 - AC Module Interface

    Air Conditioning Modules provide economical cooling in facilities without adequate HVAC. Air Conditioning Modules incorporate dehumidification circuitry and are controlled by a humidistat independent of the thermostat. The unit includes a powder-coated steel air distribution plenum mounted to the external cleanroom wall, which provides conditioned air to up to six FFUs.

    Terra can provide custom HVAC modules that operate similarly to an environmental test chamber, adjusting the supply air's temperature and humidity to maintain specific conditions within tight tolerances. This type of system is particularly useful when the environment immediately outside of the cleanroom experiences significant fluctuations in temperature or relative humidity.

    G – Environmental Monitoring
    (back to chart)

    Smart® Fan Filter Power & Control Panels centralize control over assignable groups or specific targets when conducting cleanroom pressure-balancing, troubleshooting, or maintenance. An upgraded Smart Control System allows additional environmental sensors and FFU control to meet critical performance/monitoring requirements. A control panel assembly includes power controls for the Fan/Filter Units, lights, and is configurable for other integrations including temperature, humidity, particle counts, differential pressure, and air velocity sensors.

    G1 - Temperature

    Terra's thermometers, hygrometers, and data recording instruments help monitor, control, and document environmental conditions in your cleanroom or laboratory. Temperature, dew point, and humidity monitoring are essential for products with known sensitivities to heat, environmental drift, static, or trace moisture. Terra Universal provides decades of field-proven expertise and a wide selection of thermometers and sensors for complete room monitoring.

    G2 - Humidity

    Many labs and cleanrooms choose to maintain a 30% RH level. Anything more than that may cause other issues, such as damage to moisture-sensitive materials. Every Terra cleanroom is available with integrated sensors and monitoring equipment for measuring and recording relative humidity values within the cleanroom.

    G3 - Differential Pressure

    Magnehelic® Differential Pressure Gauges monitor room-to-room pressure or filter back-pressure. Digital and alarm models are available for activating alerts when pressures fall out of specification.

    G4 - Particle Counting

    Particle counters are available as standalone handheld units for spot-checking and validation, or as built-in modules for remote monitoring after connection to a centralized building management system (BMS) such as MODBUS.

    H – Ventilation & Contaminate Control
    (back to chart)

    H1 - False Ceiling Exhaust

    False Ceiling Exhaust: Use of a plenum mounted above the drop ceiling to divert air away from the work area. A false ceiling exhaust includes an array of ceiling-mounted reverse flow fan filter units. Reverse fan filter designs remove air from the work environment and port to an outside environment or dedicated HVAC exhaust. Reverse flow fan filter units mount to the ceiling grid and are available with integrated blowers, or with motorless designs for connection to a remote HVAC blower.

    H2 - False Floor Exhaust (Complete Laminarity)

    False Floor Exhaust: Raised grated or air-permeable flooring with bottom plenum underneath to achieve full airflow laminarity. False floor exhaust systems, also known as pass through floor exhausts, feature a grated flooring that provides unidirectional airflow and passage of contaminated air. Raised flooring is common for semiconductor applications and ideal for cleanroom classifications below ISO 5 to optimize vertical laminar flow.

    p - Floor-Mounted Exhaust

    Floor-Mounted Exhausts use side-wall plenums and floor-mounted air handlers to divert air away from the work area. The plenum is mounted directly to the frame and connects to ceiling ducts that exhaust air from the negative pressure room. Floor mount exhausts include internal airflow baffles to smooth corner flow and a pass vent at the bottom with an optional fixed position damper. Containment (negative pressure) rooms require customer furnished in-house exhaust systems capable of pulling the air volume required to create adequate negative pressure

    H4 - Biosafety Levels I & II

    Biosafety Level 1 is specified as work with well-characterized agents that are known to cause disease in healthy, non-immunocompromised adults. Special containment practices and devices are generally not required, but institutional laboratory practices must be implemented to reduce risk to laboratory personnel.

    Biosafety Level 2 is specified as work that poses moderate hazards to personnel and the environment. Research or diagnostic activities that are administered with pathogenic bacteria, such as Staphylococcus aureus or Salmonella, fall into this category. This Biosafety Level builds upon Biosafety Level 1; all of the precautions and practices spelled out in Biosafety Level 1 must be followed in addition to those found in Biosafety Level 2. Special containment practices and devices are generally required to mitigate risk to laboratory personnel.

    I – Upgraded Features
    (back to chart)

    I1 - Ion Bars

    Ionization bars neutralize electrostatic charges, a common requirement for mixing, packaging, or high-speed assembly lines. Static ionizing bars remove errant charges and have special importance for products with insulative properties.

    I2 - Air Curtains

    Air curtains produce a jetstream of ULPA Class 10 micro-filtered air at the entry and exit points of a controlled environment. Air curtains are ideal when doors are frequently opened or for doorless entryways. Operating modes include either motion sensor activation with adjustable delay or continuous operation.

    I3 - Uninterrupted Power Supply

    An uninterrupted power supply (UPS) is only used to maintain power in the cleanroom for a brief time during an unanticipated power outage. A UPS guarantees uninterrupted visibility inside a cleanroom in the event of power loss and provides power for one light (LED or fluorescent) for one hour.

    I4 - Cleanroom Emergency Lights

    The cleanroom emergency light is an LED light with a backup battery that will remain on during a power outage so employees can see well enough to shut down operations, secure any sensitive products, and evacuate safely in the case that power cannot be immediately restored.

    The LED light has a red/green indicator to inform employees after power has returned and the cleanroom is safe to re-enter. When receiving power, the light both operates normally and charges the emergency battery.

    I5 - Germicidal UV Lights

    UV sanitizing modules affix to the cleanroom ceiling grid to neutralize bacteria, viruses, and mold spores. UV light is particularly effective when targeting resistant bacteria, mold/fungal spores, and gram-negative microbes. The UV-C Germicidal Lamps install on a cleanroom ceiling grid for line-of-sight room disinfection. A safety occupancy sensor switches off the UVC lighting to prevent radiation exposure when occupied.

    I6 - Fire Detection System

    Terra provides fire detection and suppression systems ideal for wet benches, exhaust fume lines, and locations involving volatile chemicals. Terra cleanrooms support traditional sprinkler and heat sensor configurations or CO2-based suppression systems. The FS System 7 is an integrated fire detection and CO2 suppression system that includes electro-optical sensors for detecting any type of hydrocarbon or non-hydrocarbon fire, even through gas or vapor. A dual-stage alarm triggers an early warning for fires too small to be sensed by overhead sprinklers. An intelligent multi-stage response system prevents the damaging effects of fire suppression in the case that a small fire self-extinguishes or is suppressed rapidly. Terra engineers work with you to determine the fire suppression system appropriate for your requirements and local fire codes.

    I7 - Fingerprint Scanner

    Biometric fingerprint scanners prevent unauthorized access via shared keys or passwords while also providing data logging capability. An integrated proximity card reader enables two-factor authentication.

    I8 - Iris Scanner

    Fully automated iris scanner for secure, hands-free access (includes data logging and optional secondary keycard reader).

    I9 - Keycard Reader

    Keycard readers provide a durable and economical method for maintaining secured keycard access within a cleanroom facility. The low-profile device reads cards up to 3" away and integrates with access control software for data logging and remote monitoring.

    I10 - Pass Through

    General-Use Pass-Through Chambers are an economical choice for non-sterile items with a low risk of cross-contamination potential including samples, fluids, tools, packaging, or documents.

    ValuLine™ Pass-Through Chambers are configurable with economical black acrylic, chemical resistance polypropylene, or stainless steel for unmatched cleanliness and durability within cleanrooms.

    BioSafe® Pass-Through chambers with continuous seam welds eliminate hard-to-clean cracks and crevices that can harbor particles and germs. CleanSeam™ design conceals the door interlock mechanism behind the chamber’s wall for a completely unobstructed, easy-to-clean chamber interior.

    I11 - Talk Through

    Communication and vocal clarity are critical for successful outcomes within cleanrooms, laboratory, and hospital isolation environments. Mechanical and electronic talkthroughs allow easier communication between internal partitions or outside areas of the cleanroom. Both the mechanical and electronic talk throughs include cleanroom-grade components and are easy to mount in either a stick-built cleanroom wall or Terra hardwall modular cleanroom.

    I12 - Interlocking Doors

    Interlocking doors are common for passthrough chambers and air showers. The interlock prevents doors on either side of the enclosure from opening at the same time. Single side access helps to maintain airflow cascades between rooms of differing pressure and limits room pressure loss after opening and closing of doors.

    Terra Universal provides uncompromising informational and consultative support for USP 797 and USP 800 compliance. If applicable, Terra will offer a 60-minute phone call with staff compounding pharmacist (CPHA Policy Committee member) Dr. Chris Munoz. Terra USP compounding suites include (as requested) custom cleanroom drawings outlining dimensions, layout, and placement of HEPA filters.

    Due to high demand for this consultation and the scope of service provided, Terra must require an up-front consultation fee that will be applied to the purchase of a Terra USP cleanroom; however, even those who do not purchase from Terra will receive cost-saving guidance far exceeding the price of this bundle.

    J8 - Seismic Structural Analysis

    Terra’s modular cleanrooms are designed with seismic safety in mind. Rigid steel frames and ceiling grids are designed with sufficient factors of safety to provide vertical and lateral strength recommended by professional engineers. Both hardwall and softwall designs can be installed to adhere to local seismic codes. Optional seismic and structural calculations can be drafted and stamped by a licensed PE to help meet municipal permitting requirements.

Power Distribution Module Diagram

  • PDMs house electrical components in an easy-access housing that makes it easy to add fan/filter units or lights if requirements change
  • Control Panel with Operation Status Indicators provides convenient access to all control and a visual confirmation of cleanroom operation
  • Plug-and-play, modular design speeds up installation, whether of Terra-furnished modular cleanroom or Terra cleanroom components used in your own cleanroom structure

Terra’s Power Distribution Modules (PDMs) dramatically simplify connection of fan/filter modules (FFUs) and ceiling lights, while providing low-voltage power for one or more Control Panels

Each PDM accommodates up to 5 lights and 5 FFUs and must be wired to a dedicated 35A fused 120V circuit or a 30A fused 240V circuit. Select among four PDM types (see configuration chart below):

UL-Listed for Highest Safety and Quality

Ensuring the safety of your employees, customers, and products is essential. Terra's UL-listed PDM's and air filtering systems are manufactured to the highest standards to reduce the risk of damage, injuries, and electrical hazards such as electric shock and fires. UL (Underwriters Laboratories) is recognized around the world as the leader in product safety testing and certification. The UL listing helps meet municipal and other permitting requirements that may be required before a cleanroom can be approved for operation. It ensures safety and integrity of high voltage cleanroom electrical system, as evaluated by independent third-party UL.

Quick-Connect Cleanroom Component Fittings
Leave Room for Growth!

If there’s chance that you may require additional FFUs to accommodate cleaner conditions, leave each PDM below its maximum FFU capacity. FFUs and lights can be added at any time, with no need for an electrician or hard-wiring, as long as the maximum of five of either module per PDM is not exceeded.

Electrical diagram for power distribution modules used on a cleanroom

Control Panel
Cleanroom control panel with touchscreen and automated environmental monitoring and control
  • Provides centralized control and monitoring of cleanroom functions
  • Typically mounted at the main entry of the cleanroom
  • Optional Night Service Mode switches FFUs into low-energy mode during off-hours to lower operating costs without shutting down the cleanroom.
  • Can be upgraded to Smart Control System for added environmental sensors and FFU control to meet critical performance/monitoring requirements.
Filter replacement alarm
Filter replacement alarm system with minihelic gauge and yellow power cable
  • Helps avoid unexpected and costly cleanroom operational interruptions by automatically alerting for cleanroom filter replacements
  • 1 Filter Replacement Alarm can cover for all Filter Fan Units (FFUs) in the cleanroom
  • Provides both audible and visual alarm
    • Audible: Buzzer with silencer
    • Visual: TUI Logo flashes
  • Includes adjustable alarm set-point to adjust frequency of filter replacement based on backpressure within a FFU
  • Typically mounts next to the cleanroom control panel
  • Connections:
    • Power: power connects to either the cleanroom’s power distribution module, or to a standard 120V/220V outlet
    • Pressure: ¼” plastic tubing connects from the alarm unit to one FFU
Night Service Switch
Night Service Swtich for Clean Room Fan Filter Units
  • Energy-saving mode saves 25% of fan operating costs by reducing power consumption during off-hours
  • Maintains round-the-clock cleanroom integrity at lower cost
  • Easy to activate via panel-mounted switch (Wireless Cleanroom Control System also available)
Why Pay More for Less?

Terra cleanrooms are designed to meet a specified ISO cleanliness rating when a cleanroom is in use: with operations in progress, process machinery humming, and personnel in motion. So why pay to maintain that level of FFU performance when a production shift ends and people, the greatest source of contamination, leave the room?

With a greatly reduced contaminant load, a cleanroom at rest maintains its target ISO cleanliness standard with much less airflow, fewer air changes—and decreased power consumption. Terra’s Night Service Switch provides this cleanliness at a nominal cost, giving you immediate cost savings.

Simply select the “Night Service” Switch when you turn off the lights and go home. A separate operation circuit drops all Fan/Filter Units (FFUs) into low-energy operation mode, shaving 25% of energy costs off your power bill while maintaining uninterrupted cleanroom performance at your specified cleanliness level. With Terra's Night Service Switch, operators can save up to 7,000 kilowatt-hours per year with a return on investment in slightly over a year.*

Ordering Information

A complete system includes fan/filter units and Terra's standard Power Distribution Modules (order separately), in addition to the units specified below. The Night Service Switch includes electronic configuration of each FFU controlled by this system. The Control Panel includes switch settings and indicator lights for Normal Mode and Night Service Mode, as well as a tamper-resistant master FFU Off switch.
