In Stock Pre-Fabricated Cleanroom Components

Since each pre-fabricated cleanroom component is tested and stocked, room pre-assembly is no longer required. Our lead times consist solely of the time it takes draw, package and ship the components to you.

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.

COVID-19 Infection Control

Terra’s in-stock ceiling-mounted reverse-flow ducted filter fan units convert any space into a negative pressure isolation room

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.

COVID-19 Isolation Room

Terra’s modular negative pressure isolation rooms, built to your specs, support patient infection control, home isolation and package quarantine

Cleanroom LED Light Panel

LED panels mount flush on ceiling grid, have longer life, and use less energy (emitting less heat) than conventional fluorescent lights.

Power Distribution Module (PDM)

Power Distribution Modules (PDMs) feature quick-connect ports and safely house all cleanroom electrical components to allow plug-and-play addition of FFUs and lights.

Operation Status Indicator Light

Modular Cleanrooms include a status indicator light in each corner, which glows when fan/filter units are operating and blinks when they are inactive.

Application-Specific Doors

Select aluminum, stainless steel frame or frameless cleanroom-rated doors with tempered glass, polycarbonate, acylic or dissipative PVC panels (shown: SS frame with polycarbonate panel).

Germicidal UV Lamp Sanitizes Labs, Cleanrooms

UV-C Germicidal Lamp installs on a cleanroom ceiling grid for line-of-sight room disinfection; safety occupancy sensor prevents personnel exposure.

Protect Against Contaminants and Pathogens

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures
