Air Shower

Preventing Particulate Contamination Entry to Cleanrooms

Cleanroom Air Showers are self-contained chambers installed at the entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are "scrubbed" by high-velocity HEPA-filtered air jets (typically 20-22 m/s or 4000-4300 fpm). Contaminated air is then drawn through the base of the unit, filtered and recirculated.
