Ordering Information

More Information

If pressure, humidity and/or temperature control or frequent cleaning and sterilization are required, Terra recommends selecting a hardwall modular cleanroom. For any questions regarding your application, please speak with a Terra representative.

Ordering Information

This chart suggests FFU quantities to meet ISO requirements for common cleanroom sizes; call for more information, or use Terra’s QuickQuote form to convey your custom ISO 5/Class 100. A complete system includes one or more Power Distribution Modules, which provide power to ceiling lights and Fan/Filter Units.

Declaration of UL Listing

For applications requiring UL-listed products, you must request a declaration of system listing under UL File E472687 at the time of order, which covers all high-voltage Modular Cleanroom electrical components integrated into Power Distribution System. UL listing helps meet municipal and other permitting requirements that may apply, while ensuring the safety and integrity of electrical components.

Night Service Switch
  • Energy-saving mode saves 25% of fan operating costs by reducing power consumption during off-hours
  • Maintains round-the-clock cleanroom integrity at lower cost
  • Easy to activate via panel-mounted switch (Wireless Cleanroom Control System also available)

Terra cleanrooms are designed to meet a specified ISO cleanliness rating while in use: with operations in progress, process machinery humming, and personnel in motion. So why maintain that level of performance when a production shift ends and personnel leave for the day?

A cleanroom at rest maintains its target ISO cleanliness standard with much less airflow, fewer air changes—and decreased power consumption. Terra’s Night Service Switch activates a separate operation circuit that drops all Fan/Filter Units (FFUs) into low-energy operation mode, shaving 25% of energy costs from your power bill while maintaining uninterrupted cleanroom performance at your specified cleanliness level (see chart below). With Terra's Night Service Switch, operators can save up to 7,000 kilowatt-hours per year based on a cleanroom system utilizing 10 FFUs.

Operation Setting Airflow: cfm (m^3/hr) Air Speed: ft/m (m/s) Run Amps (Watts)
High Speed 808 (1373) 115 (.58) 4.3 (512)
Medium Speed 717 (1218) 102 (0.51) 3.5 (416)
Night Service 654 CFM (1111) 93 ft/min (0.47) 3.3A (393W)

WhisperFlow® Cleanroom Fan Filter Units

Design features internal baffling and an aluminum diffuser to provide quiet operation along with uniform air speed for ISO-compliant laminar flow.

Aluminum Frame Swing Door

Light-weight, easy to install, and includes concealed pneumatic door closer.

Interchangeable Panels for Quick Install

Wall panels are mounted by clean and attractive mirror-finished stainless steel L-brackets that clamp the panel in place, creating a showcase cleanroom and allowing panel change-out in minutes, with no special tools.

Adjustable IsoVents™ Help Balance Differential Pressure

Cleanroom wall panels include adjustable exhaust vents to help balance differential room pressure to achieve the desired ISO requirements.

Cleanroom LED Light Panel with Emergency Power Supply, 2' x 2'

Cleanroom LED lights are equipped with emergency back-up batteries to ensure continued operation in the event of a power failure.

Adjustable Cleanroom LED Light Panels for Perfect Light Balance

Cleanroom LED panels are available with dimmable brightness and adjustable color temperature to achieve the perfect balance of light. LED panels have a longer service life, are more energy efficient, and emit less heat than conventional fluorescent lights.

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

Clean and Durable Powder Coat Finish

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.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively in conversations. Typical AC units measure ~60 dB at 100 ft. Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away.

Highest Standards For Electronic Components

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Seismic Safe Cleanroom Design

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.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. We accomplish this by harnessing high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our will to continuously improve.

High-Throughput Cleanroom Manufacturing

Over the past 5 years, Terra has manufactured nearly 1,500 UL-approved cleanrooms at industry-leading build times. Terra’s versatile modular cleanroom frame and panel designs adapt to any floor plan requirement. The UL-rated and scalable plug-and-play power distribution system further simplifies installment of FFU's and lights to cleanrooms of any size.
