Air Shower Entry Systems
Air showers are installed before the entry of a controlled environment to avoid contamination through personnel entry. Air Showers employ concentrated airflows to lift off contamination such as lint, dirt, dust etc., while an individual walks through a specially constructed chamber. The high velocity air from jet nozzles ensures efficient scrubbing action necessary to remove particulate matter and contaminated air then flows through sidewalls of the air shower and flows through pre filters and final HEPA filters.
