Barrier Pass Thru

  Containment you
can rely on

Highly Reliable Containment

PBSC’s range of barrier transfer hatches may be wall mounted or floor mounted for larger loads. These are designed to provide an air lock on the barrier which doesn’t require fumigation, see fumigation hatches and chambers on a separate page if material decontamination is required.  The barrier hatches are suitable for all BSL applications.

The standard APR pass thru is available with either mechanical or inflatable seal doors. The inflatable seal doors utilises high performance inflatable seals mounted into solid leaf phenolic resin door leafs. Integrity of the chamber is assured by fully welded stainless steel construction.

Venting and chamber conditioning may be provided and fully welded gas tight duct connectors. HVAC ball valve dampers are available.

Due to the custom nature of APR transfer hatches – please consult our technical department with your project parameters. 

Leakage rates available on request.
