ColPro Pass Airlocks

Beth-El's Single or Multistage Airlock for Compartments with Collective NBC-Protection Systems

The ColProPass Airlock System provides the capability to move in and out of a shelter without the system loosing positive pressure or contaminating the toxin free area (TFA), an important component for shelters with collective CBRN protection systems.

The ColProPass is a ventilated single or multistage airlock that is purged by the air released from the toxin-free area (TFA). The air flows from the TFA, through the airlock, and is released through an overpressure valve on the outer airlock door.

Optionally, the airlock can be delivered with an additional recirculation filtration unit installed in one or more of the chambers, which reduces the necessary purging time significantly.
