Manufactured by Esco Technologies
A cost effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement.
Controlling the ingress of particulate contamination into cleanrooms and other controlled environments is paramount in order to maintain the integrity of products and processess. Personnel traffic is the most important factor which must be controlled. Esco Pass Boxes and Transfer Hatches are a cost effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement. They may also be used to protect the external environment from egress of contamination, for example, in biological safety laboratory applications.

Features of Air Shower Pass Box
- Built-in air shower significantly reduces surface contamination on materials entering or exiting the controlled environment. Materials entering or exiting the controlled environment are “scrubbed” by high velocity ULPA filtered air jets with velocities of 25 m/s (4921 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.
- An array of stainless steel nozzles direct high-velocity jets within the chamber.
- Air shower duration is adjustable. Standard factory pre-set is 12 seconds in both directions.
