Pass-Through Chambers
Terra manufactures pass-throughs for both modular and conventional, fixed-installation cleanrooms and laboratories.

Available in dozens of standard sizes and six materials, including 304/316 stainless steel and application-specific plastics. Terra pass-throughs provide industry-leading quality and durability. Mechanical and electronic interlocks help prevent contamination of controlled areas, and a number of slide-up and roll-up doors eliminate clearance requirements and conserve valuable cleanroom space.

Terra's Air Showers features adjustable nozzles that wash personnel with a high-velocity flow of HEPA-filtered air (between 8000 and 10,000 fpm) as they enter the cleanroom, removing surface contaminants. This programmable controller lets you determine the cycle and alarm times.

Whatever your application, Terra provides a fully integrated, turnkey system.
