Item # 667, Atmos-Tech Personnel Air Showers

Air Showers offer an effective way to reduce contaminants carried by individuals entering or leaving a controlled area. The Air Shower can be the solution to many contamination problems.

Air Shower Tunnels are protected passageways that allow large quantities of personnel to pass into controlled areas.

Air Showers and Tunnels supply concentrated CLASS 100 sterile air flows to remove contamination while an individual stands in or walks through a specially constructed air chamber. Pressurized air streams from nozzles at a velocity ranging from 6,000 to 10,000 feet per minute. This ensures the efficient scrubbing action necessary for the removal of particulate matter. Contaminated air is directed downward through the grilles and hollow walls of the Air Shower to the filter. Particles as small as 0.3 microns are removed with 99.99% efficiency.

ATMOS-TECH Air Shower Tunnels are used as downflow booths to remove particulate contamination from personnel entering clean rooms and sterile rooms. The Air Shower Tunnel is designed as a combination of basic floor plan styles placed either side by side or end to end. Air Showers and Tunnels meet all federal, military and industrial specifications for use with life science, bio medical, pharmaceutical, parental drug, microelectronic, aerospace, precision manufacturing and other applications. All Air Showers and Air Shower Tunnels manufactured by Atmos-Tech are warranted for a period of one year from the date of delivery.

Atmos-Tech Air Showers and Air Shower Tunnels are economical to operate and require minimal maintenance.
