Air Showers offer an effective way to reduce contaminants carried by individuals entering or leaving a controlled area. The Air Shower can solve many of your decontamination problems. Air Shower tunnels are protected passageways that allow large volumes of personnel to pass into controlled areas. Air Showers and Tunnels supply concentrated CLASS 100 sterile air flows to lift off contamination while an individual stands in, or walks through, a specially constructed air chamber. Pressurized air streams from nozzles at a velocity between 6,000 and 8,000 feet per minute, which ensures efficient scrubbing action necessary to remove particulate matter. Contaminated air is directed downward through grilles and hollow walls of the Air Shower to the filter. 99.97% of all particles as small as .3 microns are removed. Halco Air Showers and Air Shower Tunnels are economical to operate, and require a minimum of maintenance.
