Air Shower Pass Box

Controlling the ingress of particulate contamination into cleanrooms and other controlled environments is paramount in order to maintain the integrity of products and processes. Personnel traffic is the most important factor which must be controlled. Air Shower Pass Box and Transfer Hatches are an effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement. 

Features of Air Shower Pass Box

  1. Built-in air shower significantly reduces surface contamination on materials entering or exiting the controlled environment. Materials entering or exiting the controlled environment are  high velocity ULPA filtered air jets with velocities of 25 m/s. Contaminated air is then drawn through the base within the unit, filtered and recirculated.
  2. An array of stainless steel nozzles direct high-velocity jets within the chamber.
  3. Air shower duration is adjustable. Standard factory preset is 12 seconds in both directions.
