Not Shown: Range of Options - Other options include vacuum, DI water and gas utilities
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.
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.
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.
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.
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.
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.
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.
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.
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.
J1 - Cleanroom Installation
Terra Universal is one of few cleanroom manufacturers to provide in-house engineering, in-house design services, and in-house component manufacturing from a single source. While most contractors rely on external engineering teams for drafting and floorplanning, Terra reduces layers of communications and simplifies facility planning and construction to a single point of contact. If requirements change, our modular design allows you to add filters, lighting, ionization, or additional floor space—all at a fraction of the cost you'd face with other systems.
J2 - White Glove Delivery

We offer comprehensive decontamination service packages for a multiverse of cleanroom applications, gown rooms, vivariums, biomedical facilities, laboratories, and cold/dry rooms.
J7 - USP <797> Consultation
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.
Engineered for ease of installation and cleaning, BioSafe Cleanroom wall panels come in standard 4-foot widths and heights ranging from 7 to 12 feet. Their modular design lets you configure a custom cleanroom using pre-engineered components, many of which are inventoried at Terra’s Fullerton, California manufacturing facility.
Terra technicians assemble and test each BioSafe Cleanroom to ensure it meets performance requirements prior to packaging. Panels and other components are labeled before crating to simplify installation, which typically requires no special contracting or permitting (on-site installation and testing services are available). Whether your requirements call for a single room or a multi-suite facility, your BioSafe Cleanroom is operational in a fraction of the time and at a fraction of the cost associated with conventional cleanrooms.
Each wall section is composed of two panels that snap together, with space in between for insulation or utilities, similar to a conventional wall. Wall sections are bolted end-to-end to form a continuous interior wall surface with very fine seams that can be caulked if necessary. Wall panels can be fitted with flush-mounted BioSafe windows or any of Terra’s cleanroom door designs. Certain panels will include the required exhaust vents; customers can specify the addition of an exterior exhaust plenum that covers these vents and directs exhaust airflow to an external air handling system. Air return plenums may also be used to recirculate conditioned air to maintain suitable working temperatures and save energy.
BioSafe wall panels function equally well as exterior and interior cleanroom walls, which simplifies engineering of multi-room facilities. Corridors and anterooms can be added where necessary by regulation or to provide additional barriers against cross-contamination. These intermediate spaces help to maintain proper air pressure by providing neutral buffer spaces. They also may serve as convenient staging areas for supplies and other materials. Pass-through chambers can also be used for more staging and transfer, as well as simply limiting the number of personnel in a critical area.
The modular ceiling grid can be configured for different ISO-classifications through appropriate placement of fan/filter units. FFUs can be positioned (and repositioned) in the ceiling grid to concentrate clean air in the most critical processing areas. Rooms with less critical cleanliness requirements may operate with fewer FFUs, reducing energy and maintenance expenses. For example, a gowning room may only need one FFU to ensure a slight overpressure that limits leakage.
As FFU configurations become more complex, Terra can provide more advanced control systems, from PLC touchscreen controllers to fully automated air balancing systems. In addition, security measures can be integrated into the various access points of the cleanroom, including biometric scanning equipment and access logs.
