Features & Benefits

Features and Benefits

ULPA Filtered Air Curtain Provides Protective Barrier of Micro-Filtered Air

Cleanroom air curtains provide a blade-shaped shower of ULPA-filtered air (99.999% effective at catching particles down to 0.12 microns), acting as a barrier to protect against particles and ambient air from entering a controlled environment.

Versatile Mounting Locations

Cleanroom air curtains are useful over any of type and size of opening to control temperature and/or contamination

Control Temperature and Contamination

Ideal for pharma, medical device, or food/beverage operations to control temperature and contamination between a controlled and uncontrolled space.

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.
