Air Shower Entry Systems  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.
