    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.

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.

    C - Filter Replacement Design
    (back to chart)

    C1 - Top-Side Fan Filter Units

    Top-side replaceable filters are a standard package available with Terra fan filter units. Standard FFUs offer a lower cost option and are ideal for small-scale and less critical cleanroom operations. To change the filter, the unit must be entirely pulled out of the ceiling bay. Climbing up to remove the bulky FFU can be difficult, dirty, and hazardous. The procedure may require tall ladders, multiple people, personal protective equipment, and perhaps worst of all, shutting down the cleanroom.

    C2 - Room-Side Fan Filter Units (RSR)

    Room Side Replaceable (RSR) fan filters eliminate the need for access to a roof or overhead ceiling space when conducting fan filter maintenance and replacement. Breaching the cleanroom ceiling is not required when installing or replacing RSR fan filter units or their HEPA filter media. The filter media is easily accessible from inside the cleanroom, an ideal trait for facilities with restricted ceiling heights or for pharmaceutical operations that require more frequent HEPA filter replacements.

    D - Fan Filter Motor Type
    (back to chart)

    D1 - Electronically Commutated (EC)

    Terra's Smart® electronically commutated (EC) brushless motors include an internal microprocessor and MODBUS® networking control card. Easily integrate your fan filter with a building management system, control panel, or additional air pressure, airflow, and particle count sensors.

    D2 - Permanent Split Capacitor (PSC)

    PSC motors are priced for affordability but are significantly less energy-efficient than their EC counterparts.

    (back to chart)

    H1 - Integrated LED Fan Filter Light

    Fan filter units with integrated LED lights enable 100% coverage of a ceiling grid with fan units while also providing adequate lighting. 100% integration of the ceiling grid is typically reserved for high-performance environments with ISO Class 5 ratings or cleaner.

    H2 - Integrated Fan Filter Ionizer

    Integrated ionizers provide a continuous stream of static-neutralizing ions to protect sensitive materials against ESD. Built-in ionizers enhance cleanliness by neutralizing charges that attract and hold particles on walls, tabletops, and other surfaces. Ionizers are known for being maintenance burdens that require frequent calibration. Unlike ionization technologies offered by Terra competitors, Terra systems require no calibration and automatically maintain a balance of ± 50 volts.

    H3 - Automated Fan Filter Control & Pressure Balancing

    Terra's Smart® Fan Filter Units paired with Smart® Cleanroom Control Panels adjust the fan speed up or down to “dial in” the proper air velocity, internal pressure, and air change rate. Variable fan filter control lets you balance FFU performance from one clean zone to another, ensuring that you maintain the pressure gradients and air change rates required. As the filters mature and air velocity decreases, the system lets you perform small speed adjustments that keep your cleanroom performing to spec.

    H4 - Portable Fan Filter Units

    ValuLine portable fan filter units are mobile, self-contained, hospital-grade HEPA purifiers mounted on a rolling stand. The small footprint, rolling stand, and plug-and-play operation allow easy transfer between rooms or departments.

    H5 - NEC Class 1/Division 1 Compliant

    Terra's explosion-proof fan filter units isolate fumes and vapor from any spark, hot surface, or friction-inducing electrical components.

    Explosion-proof LED lights are available with a T5 temperature rating and are designed for low-profile pendant mounting to make maximum use of available space.

    Division I environments contain ignitable concentrations of hazards under normal operating conditions and/or where the hazard is caused by frequent maintenance or repair work or frequent equipment failure.

    Class I locations are those in which flammable vapor and gases may be present.

    H6 - Remote Air Supply Connection

    Terra's Laminar Flow Diffusers with HEPA Filters include a 12"-diameter collar for air supply connection for connecting the fan filter assembly to a remote air source. Threaded inserts in the top corners accommodate eyebolts to facilitate installation using suspended guy wires (order eyebolt packages separately).

    H7 - 8" Tall Unit for Restricted Height Spaces

    Low-profile 8"H fan filter units are ideal for cleanrooms installed within restricted height areas.

    H8 - Integrated UPS Battery System

    An Uninterruptible Power Supply (UPS) is a backup system that provides battery power to fan filter units when utility power is unavailable. In the event of a power outage, the UPS immediately activates without interruption and recharges when power is restored.

    Smart® EC Fan Filter Units with UPS keep your FFU running long enough to safely store away contamination-sensitive materials, shut down work-in-progress, and/or switch to a backup power generator. Handy and convenient, the Uninterruptible Power Supply (UPS) provides power when and where you need it. The included external 24V battery pack offers extended battery runtime when used with the main tower UPS system.

    H9 - Cleanroom Fan Filter Contaminant Collector Pan

    A fan filter collector pan accumulates dust particles that dislodge from the HEPA filter, preventing contaminants from re-entering the cleanroom. Terra's collector pan integrates with bag-in/bag-out (BIBO) systems and is easily removed for cleaning or maintenance.

    Bag-in/Bag-out (BIBO) modules are optional accessories for applications involving toxic fumes or biohazards. BIBO modules seamlessly integrate with the filter media system for safe filter disposal and replacement from the inside of the room for contact-free removal of filters with potentially hazardous airborne contaminants.

    H10 - Fan Filter Heating Element (up to 150°F)

    Heated fan filter units provide high-temperature air of up to 150 degrees Fahrenheit.

    H11 - Fan Filter VOC Removal Adapter

    Volatile Organic Compound (VOC) Removal Adapters require an adapter module for each FFU. The package includes an adapter housing, one charcoal pre-filter, two sanitizing modules, and one PCO panel and must be ordered together with a Terra WhisperFlow FFU.

    Photo-Catalytic Oxidation Panels (PCO) remove volatile organic compounds (VOCs) remaining in the air stream after they pass the carbon filter. The PCO panel is highly efficient at vapor removal, yet imposes no restrictions on airspeed, allowing the Fan/Filter Module to maintain airspeed consistent with ISO cleanliness requirements (typically 80-100 feet/minute).

    The carbon pre-filter removes volatile organic compounds (VOCs) to ensure a safe, clean processing environment. The pre-filter also helps compensate for VOC spikes that might occur during certain operations.

    H12 - Fan Filter UV Sterilization Module

    Terra Fan Filters Units with integrated UVC decontamination modules provide additional protection against bioaerosols and pathogenic organisms. UV-C lamps may not produce an entirely sterile surface, but they can maintain consistently low microbial loads throughout a wide range of operations and eliminate bioburden spikes that could necessitate extensive testing and decontamination measures. UV Sterilization modules are not compatible with the following FFU designs: Narrow, Explosion Proof, or Reverse Flow.

    H13 - Cleanroom Leak Testing Challenge Port

    Fan filter units with challenge ports provide a simple and efficient mechanism for conducting localized leak tests of each filter. Terra fan filter units are leak tested before delivery in accordance with IEST and UL 900 standards. For critical applications, the USP <797> framework requires that fan filter units undergo leak testing during initial installation, and semiannually throughout the life of the filter. Filter testing is also common in operating rooms, surgical suites, and CGMP facilities.

    Leak testing requires the injection of an aerosol upstream of the filter. Fan filters with challenge ports allow for rapid and individual testing of each fan filter unit without requiring the introduction of test aerosols to the entire HVAC system. Challenge port testing is a more reliable method of ensuring that a test aerosol is uniformly applied and presents fewer variables.

    I - Compatible Control Systems
    (back to chart)

    I1 - Cleanroom Fan Filter Power Distribution Module

    Terra’s Power Distribution Modules (PDMs) use 3-pin or 4-pin quick connect fittings to power all FFUs and lights, regardless of the cleanroom size. The expertise of a licensed electrician is only needed to connect the main voltage to the Primary, Secondary, and Booster PDM modules; lights and fan filters are installed via quick-connect fittings without requiring hard wiring. The PDM modules must be wired to a dedicated 35A fused 120V circuit or a 30A fused 240V circuit to allow a quick fit connection of up to 5 light and 5 FFU connections per module.

    I2 - Cleanroom Fan Filter Replacement Alarm System

    Fan Filter Replacement Alarms provide a reliable, quantitative method for determining when HEPA fan filter media requires replacement. Automatic replacement alerts avoid costly and unexpected operational interruptions while also maximizing the working life of the fan filters.

    I3 - Smart Control Panel for Filter Fan Units

    Standard Control Panels provide central control and connection of lights and filters. 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. The robust system offers advanced control for up to 200 fan filter units and 16 independently controlled rooms.

    An upgraded Smart® Control System allows additional environmental sensors and FFU control to meet critical performance/monitoring requirements including programmable fan speed adjustment for energy savings, performance enhancement, or remote shutdown. Easily connect additional sensors to display humidity, differential pressure, and temperature data.

    J - Compatible Accessories
    (back to chart)

    J1 - Cleanroom Fan Filter Unit Mounting Frames

    Stainless steel mounting frames allow fan filter units or light panels to be installed in drywall or other hard ceilings without a ceiling grid.

    J2 - Cleanroom LED Lights

    Cleanroom LED lights are energy-efficient, produce low heat, carry long life spans, and are compatible with ISO class 3 spaces.

    J3 - Cleanroom UV Lights

    Although UV-C lamps may not produce an entirely sterile surface, they can maintain consistently low microbial loads throughout a wide range of operations and eliminate bioburden spikes that could necessitate extensive testing and decontamination measures.

    J4 - Cleanroom Emergency Lights

    Cleanroom LED Light Panels with Built-In Emergency Batteries allow for temporary backup lighting during a power outage. When receiving power, the light operates normally and charges the emergency battery. A UL recognized emergency driver allows the LED fixture to be used for normal and emergency operation. The LED light has a red/green indicator to inform employees after power has returned and the cleanroom is safe to re-enter.

    J5 - Cleanroom Ceiling Panels

    Cleanroom ceiling panels cover ceiling bays not occupied by fans or lights. These panels are available in several materials that support frequent cleaning and will not absorb water or crumble like conventional gypsum ceiling panels. Chemically resistant polypropylene panels are preferable for use with most chemical solvents and acids. Stainless steel panels are typical for pharmaceutical and USP-regulated environments that require aggressive chemical sterilants or vapor treatments during cleaning regimens. Vinyl-covered gypsum is cost-effective and fire-rated but does not offer the wider chemical compatibility of other materials. All Terra ceiling panels are cleanroom appropriate for ISO Classes 5 to 8 and Federal Standard 209 Classes 100 to 100,000.

    B2 - Powder-Coated Steel: More economical than stainless steel, durable and rigid powder-coated steel is more resistant to chemical- or moisture-based corrosion than plastic designs.

    B3 - 304 Stainless Steel: 304-grade stainless steel resists most harsh chemicals and alcohol-based cleaning agents, and won’t produce contaminants during sterilization.

    B4 - 316 Stainless Steel: 316-grade stainless steel contains more nickel and molybdenum than 304-grade stainless steel, enhancing its resistance to corrosion in wet environments, degradation from bleach-based disinfectants, and high-temperature sanitation, like autoclaving.

    B5 - Electropolished Service: Electrochemical polishing improves the surface finish of the stainless steel, and supports easy sterilization to reduce micro-cavities where microbes colonize.

    C - CleanSeam Design:
    (back to chart)

    C1 - Continuous Seam: Terra’s CleanSeam™ pass through chambers feature fully-welded chambers with smooth, continuous seam welds for a seamless interior that is easy to disinfect. The internal chamber is free of crevices or cracks where contaminants can collect.

    D - Double-Wall Design:
    (back to chart)

    Equipping a pass through cabinet with external components - such as door sensors, lighting and filtration – can be a challenge. Cleaning procedures dictate that pass through chambers should be seamless, crevice-free and easy to wipe down. Installing external components on the chamber will make the cleaning process more difficult and restrict the space available for sample transfer.

    Terra has solved this issue with CleanMount® double-walled pass through chambers. All external components are enclosed within the space between the internal and external walls, so the integrity of the internal chamber is not jeopardized and the pass through cleanliness rating is not sacrificed.

    Double-wall construction has additional benefits: the unit is more rigid and more stable within the wall, the doors achieve a tighter seal and more precise alignment with the chamber, and the interlocking mechanism operates flawlessly.

    CleanMount® double-walled systems provide one additional benefit: they are pre-compatible with a wide array of Smart® electronic add-on features, such as UV lighting, HEPA filtration, refrigeration modules and load presence sensors. As the bulk of the additional cost for these add-on features are built into the double-wall design, Terra’s pass throughs can be fully equipped with Smart® electronic controls for a negligible price. While the cost to add these features is low, the benefits are enormous - your pass through chamber is instantly transformed into more than a sample transfer system: a germicidal system, a method for employee communication, a data logger, or a security device.

    D1 - Isolated Interlock: Effectively cleaning an internal chamber with an exposed interlock is a huge challenge. Terra offers a fully isolated automatic interlock, installed between the interior and exterior wall panels of the cleanroom transfer hatch.

    D2 - Flush-Mount: Terra’s CleanMount® system mounts flush against the cleanroom wall to minimize particle accumulation and simplify cleaning.

    D3 - Quick Install: The whole process of installing a pass-through was very messy, until Terra developed the CleanMount® pass-through. The CleanMount® fastening system installs directly into a clean, finished opening in the wall (not a dirty, rough cut-out) without any drilling or screwing into the surrounding wall that can contaminate and delay cleanroom operations. The innovative design firmly clamps to a variety of wall thicknesses without penetrating or damaging the finished surrounding wall. After the wall is fully prepared by your contractor, Terra’s CleanMount® pass through chamber can be installed seamlessly, within 5 minutes. Terra’s video tutorial will guide your contractor through the process to ensure the pass through is correctly installed.

    D4 - Contamination-Free Removal: CleanMount® pass throughs also drastically simplify maintenance to minimize downtime of critical cleanroom operations. The units can be removed and reinstalled seamlessly, within minutes, by any member of your organization. If your pass through chamber needs servicing, Terra’s CleanMount® chamber easily slides out of the wall without creating scratches or abrasions that can leave debris and particle contamination in the cleanroom.

    D5 - Lipless Front/Rear Edges: The edges of a pass through chamber are prone to snag garments and collect contaminants. Terra’s CleanMount® and BioSafe® design includes lipless front and rear edges for easy sterilization.

    D6 - Rounded Corners: The corners inside a pass through chamber are a common spot for contaminates to collect or microbes to colonize. Terra’s CleanMount® and BioSafe® pass throughs feature fully rounded (radius) corners for easy disinfection.

    D7 - Lift-Off Replaceable Doors: Effectively disinfecting pass-through doors can be a challenge. Both Terra’s CleanMount® and BioSafe® pass-through chambers include removable doors. BioSafe® passthroughs feature autoclave-safe doors with blue elastomeric door seals.

    E - BioSafe Design:
    (back to chart)

    E1 - Meets Aseptic Requirements: Terra’s pass through chambers are UL-rated, CE-marked and leak-tested. Specialty models meet USP <797> and <800> requirements, cGMP standards, UL-B fire ratings, and BSL 1 and 2 criteria. If you’re installing a pass through into a regulated space, talk to your Terra product specialist to find a model to fit your application.

    E2 - BioSeal Door with Knife Edge Seal: For many applications, maintaining positive or negative pressure inside of a cleanroom is critical, whether the environment is sensitive to particles, microbial growth, moisture or static build-up. Your cleanroom’s pressure rating can be compromised by any personnel entrance or exit, including your pass through chamber. Terra’s pass through chambers will support the integrity of your cleanroom, allowing it to maintain your desired cleanliness levels and specifications. Terra’s BioSeal™ doors with elastomeric gaskets are pressure-rated, autoclave-safe and compatible with critical, regulated environments.

    F - Smart Pass-Through Design – Standard Features:
    (back to chart)

    F1 - Electronic Door Interlock: Pass through chambers must be designed to prevent both doors from opening at the same time, causing cross contamination between two sterile spaces and a loss of your cleanroom’s pressure rating. A critical component in the pass through design, the interlocking mechanism, prevents this unwanted occurrence. The interlock can be mechanical, utilizing a hook and latch system, or electrical, using an e-strike. Mechanical interlocks come in two flavors: manual or automatic. For mechanical interlocks, Terra only offers automatic systems, as manual systems must be engaged by the operator, severely reducing transfer efficiency. In certain applications, Terra pass through chambers are opened every five seconds for the entirety of a work shift. This level of access frequency would not be possible with a manual, mechanical interlock. Electrical interlocks are often installed on passthrough chambers with automatic, hands-free doors or systems equipped with access controls, occupancy sensors, building management integration or event logs. Terra’s Smart® pass-through chambers can be equipped with these capabilities and more, including refrigeration modules, intercoms, UV germicidal lighting and HEPA filtration.

    F2 - Electrical Integration/Control: When first introduced to the market, the pass through chamber had one specific job: to act as the gatekeeper for sample transfer into and out of the cleanroom, thereby reducing personnel traffic. As the pass through has become more integral to the operations within a cleanroom, the potential jobs it can perform and problems it can solve have increased. Terra has changed the definition of the pass through chamber by offering a menu of standard, add-on features that expand the role of the pass through chamber within a cleanroom. Beyond sample transfer, a pass through can now disinfect products, allow employees in separate areas to communicate, log environmental conditions, track personnel or packages, and add layers of security to your facility.

    F3 - Service & Open Door Alerts: In regulated environments, like FDA or cGMP facilities, event logs that track employee movement, environmental conditions, equipment status, and service alerts are a requirement. Terra’s Smart® Pass Through captures these data and communicates with your building management system or LIMS software to export the data at stated intervals.

    F4 - Door Status LED Display Bar: The interlocking mechanism is the lifeblood of the pass through chamber; its integrity dictates the life of the unit. If the interlock doesn’t function effectively, your facility may experience sample cross contamination, product failures, or employee safety issues. The interlock, and by proxy, the pass through doors must be operated correctly; misuse can shorten the lifespan of your pass through and decrease its effectiveness. To reduce interlock abuse, Terra has introduced several solutions, such as buzzers and color-coded warning signals. Terra’s Smart® LED Door Status Bar displays a red light when the opposite door is open, informing the operator to wait before attempting to open the door, and a green light when the opposite door is shut, informing the operator to proceed in opening the door. Without a status bar, interlock abuse is common: an operator will attempt to open the door, not knowing that the opposite door is open; when their door doesn’t open, the operator will use excessive force to pry the door open, causing damage to the door seal and the interlock. These signals act as the traffic lights for Terra’s Smart® pass through chambers, ensuring interlock abuse is prevented. If traffic lights didn’t exist on roadways, would car accidents be blamed on automotive manufacturers? In this same vein, Terra has taken the extra step in supporting pass through care, so our customers can reap the full benefits of our system for many years.

    G - Smart Pass-Through Options:
    (back to chart)

    G1 - Hands-Free Automatic Door: In the semiconductor industry, the highest level of contamination control is achieved by totally eliminating the presence of humans in the critical manufacturing areas through full robotic automation and closed-loop enclosures. Terra Universal has developed and offered solutions for the semiconductor industry since its inception in 1976. We understand the benefits that reducing foot traffic will have on a company’s operations, processes and products. Terra’s Smart® pass through chambers can be equipped with automatic doors and electronic controllers that support integration with fully automated systems.

    G3 - Recessed LED Lighting: LED lighting illuminates the internal chamber and mounts flush into the ceiling for easy sterilization. The light automatically activates when either door opens, supporting hands-free operation of the pass through chamber.

    G4 - UV-C Sanitizing Module: Germicidal UV-C light, emitted at 254 nanometers, denatures microbial DNA after short, intense exposure. UV-C lighting will ensure your pass through box is fully sterilized and does not impact the bio-burden of your cleanroom.

    G5 - ULPA/HEPA-Filtered Air Shower: Recirculating filtered pass throughs use a closed loop system to continuously recirculate air in the chamber through built-in HEPA or ULPA filters. These clean air pass thrus are self-contained and do not require any ventilation or exhaust ducting. They run continuously to reduce particle concentration within the chamber. This design is commonly used because the closed-loop system does not impact adjacent room pressure balances when operating.

    With heavily mandated cleanliness requirements associated with USP 797 and USP 800 cleanrooms, a pharmacy pass thru is a vital point for sterile pharmaceutical compounding. Terra’s HEPA filtered pass through and Smart® HEPA filtered pass thru use recirculating ventilation to meet and exceed USP 797 and USP 800 guidelines.

    Comprehensively wiping down a cart filled with patient samples or supplies can be time consuming. Terra’s high velocity air shower pass through is designed with high-pressure nozzles that wash the cart from every side with ULPA-filtered air. After a 30-second, hands-free wash cycle; your cart will be clean, particle-free and contamination-free. As a secondary disinfection mechanism, equip your cart with a germicidal, UV-C light to prevent microbial growth.

    G6 - Refrigeration Module: For temperature sensitive samples or equipment, Terra’s Smart® pass throughs may be equipped with a refrigeration module that maintains a 4°C set point within the internal chamber. Terra’s high-security, refrigerated pass through chambers are utilized for overnight storage of patient samples.

    G7 - Pushbutton Intercom: Built-in intercom system allows operators to easily communicate between rooms. Without intercoms, operators are prone to opening both pass through doors, by bypassing the interlock, to communicate, thus breaking the cleanroom seal and exposing sterile areas to cross contamination.

    G8 - LCD Message Panel: LCD panels are designed for regulated environments, like FDA, cGMP, GLP or USP <797> facilities. They display critical environmental information related to the interior chamber conditions, such as temperature and relative humidity.

    G9 - 90° Corner Configurations: Terra has 45 years of experience in customized equipment. Smart® pass-throughs with custom door configurations can be designed per-project to install in corner walls with multiple doors: 2 doors (L-shape), 3 doors (T-shape), or 4 doors (X-shape).

    G10 - Load Presence Sensor: Infrared beams detect objects placed within the internal transfer chamber and can communicate data to an audible alarm or sample tracking system. They are ideal for highly-regulated facilities maintaining cGMP compliance or systems installed onto the external wall of a building for package delivery.

    G11 - Video Camera: An interior HD video camera records continuously or upon door opening. The camera can also be adjusted to monitor spaces external to the pass through chamber.

    G12 - Proximity Card Reader: Card readers with system lockout and keypad for two-factor authentication are ideal designed for pharmacies dispensing controlled substances.

    G13 - Keyless Door Access Panel: Keypad readers for high-security areas prevent unauthorized access to the pass through chamber.

    G14 - Fingerprint Reader: Biometric fingerprint scanners include proximity card reader for two-factor authentication.

    G15 - Iris Scanner: A fully automated iris scanner provides secure, hands-free access and includes data logging plus a secondary keycard reader.

    G16 - Access Data Logging: This software logs environmental conditions and exports the data to a local server or building management system.

    G17 - Laminar Flow HEPA Filtration: Terra’s Smart® pass through cabinets may be equipped with a HEPA-filtered blower module, installed above the unit, that washes the internal chamber with uniform, unidirectional, micro-filtered air.

    G18 - Ionization Module: Ion bars emit a static neutralizing stream of cations and anions to prevent ESD discharge. They are ideal for protecting static-sensitive medical devices and microelectronics.

    H - Fire-Rates Pass-Throughs:
    (back to chart)

    H1 - Fire-Rated Doors: If you are installing a pass through chamber in a fire-rated space, the pass through must carry the same fire-rating as the wall in which it is installed. Terra’s fire-rated pass through chambers carry the UL-B label for 90-minute fire exposure, suitable for installation in areas with 2-hour wall ratings. Available in 11 different sizes to fit your sample transfer needs, Terra offers fire-rated units that are pre-tested, crated and in-stock for immediate shipment.

    I - Other Optional Accessories:
    (back to chart)

    I1 & I2 - BioSafe Removable Racks and Shelves: Stainless steel racks and shelves can be removed for disinfection or replaced as user requirements change.

    I3 - CleanTop Sloping Top: For non-flush mount pass through systems, Terra’s CleanTop™ sloping top provides a smooth, easy to disinfect surface between the pass through door and the wall.

    I4 - Ventilation Module: A cleanroom pass thru chamber with exhausted ventilation (also known as a sink airlock) provides a single pass (open loop) supply of exhausted air. This extraction system creates negative pressure to prevent particles from escaping the chamber from either door. This design can be used for applications where hazardous materials or particulates must be contained and kept from passing through either side of the chamber. Ventilation units can also be used to duct fumes that might be present in a specimen, allowing the cleanroom pass thru box to act as a drying system. Specify a flange adapter to allow connection from the pass thru chamber to an in-house ventilation system. Exhaust air speed sensors can also be configured for added safety to alarm in the event air speed falls below a specified set point.

    I5 - Grounding Terminals: For static-sensitive material, Terra’s cleanroom pass through box can be equipped with grounding terminals for an ESD-safe internal chamber.

    I6 - High-Velocity side & Top HEPA Air Shower: Installed on floor mounted pass throughs, the air shower directs HEPA-filtered air through high-velocity nozzles installed on the ceiling and walls of the internal chamber to wash carts free of dust and contaminants.

    I7 - Large-Clearance Roll-Up Doors: Terra’s roll-up door pass throughs are designed for consistent, high-throughput transfer of large, bulky equipment into and out of the cleanroom. Roll-up pass thru designs include safety pressure sensors, automatic interlocks, touch panel interfaces, and laser door positioning sensors.

    I8 - Reinforced, Ruggedized Contruction: Rugged pass through transfer hatches featuring double-wall construction and heavy-duty self-closing doors are designed for high-throughput, high-security areas such as correctional facilities.

    I9 - Locking Latches: For secure areas housing controlled substances or high-value products, Terra offers a variety of locking door latches and access controls for pass thru cabinets.
