Materials entering or exiting the controlled environment are “scrubbed” by high velocity ULPAfiltered air jets with velocities of 25 m/s (4921 fpm). Contaminated air is then drawn through the base within the unit,...

Esco Air Shower Pass Box Airflow Diagram Blower ULPA Filter ULPA-filtered air Unfiltered / Potentially contaminated air Room air / Inflow air Air is forced by the blower(s) through ULPA filter(s) which are 99.999% efficient against particles of 0.3 microns. Filtered air is ejected through nozzles at high velocities into the chamber. These turbulent air streams disperse particulate matter on all surfaces. Dispersed particulate matter migrate with the air stream towards the lower areas in the air shower chamber. The air is continuously filtered and recirculated. Esco Air Shower Pass Box...
