HVAC Upper Air UV

Upper Air UVC Germicidal Fixtures

Wall-mounted, and ceiling-suspended, fixtures, directly expose the air in upper areas of rooms to constant UVC energy. Properly sized and installed UVC upper air equipment is the most effective way to lower the level of microorganisms in an occupied space.

Upper air UVC fixtures are recognized by the CDC, WHO, and ASHRAE as effective solutions for lowering airborne microorganisms. It was manufacturing upper air UVC fixtures that American Ultraviolet started with over 60 years ago - safe, effective, and economical air disinfection solutions made in the U.S.A. These trusted fixtures have been successfully used in hospitals, schools, prisons, healthcare environments, office buildings, and government buildings, just to name a few.

The CM, TB, TB-LED, STBF, and RAM Upper Air series in-room fixtures are designed specifically for safe, continuous air disinfection, which helps clean the air in occupied spaces. The determination of the ideal upper air fixture for your application is based on the square footage of the room and intended use.

The CM, TB, and STBF fixtures incorporate adjustable louvers that safely direct UVC energy above the occupied space (7 1/2 + feet). The RAM series units are fully enclosed, and tamper-proof, and use internal fans to actively draw in and recirculate the air within the space.
