Barrier Hatch HC-BH

These hatches are used in a broad range of applications from pharmaceutical facilities BSL2 through to BSL4. At the higher end of the containment spectrum, our hatches can be fitted with pneumatic seals and sophisticated access and control options.

Hatches can be installed into preformed openings in cast concrete walls, block or stud walls.

For applications without containment please see PBSC’s standard transfer solutions A-HT and A-TH.
