Overview

PBSC’s inflatable seal doors provide the highest possible airtight containment in applications involving high traffic and wheeled equipment. The doorframe is flush with the floor eliminating any trip hazard or trolley interference.

The seal around the perimeter of the door is inflated by compressed air against a radiused doorframe and provides excellent leakage resistance up to pressure differences of 2000Pa (8” w.g.).

The door leaf is available in polished stainless steel, powder-coated low carbon steel, aluminium, or solid core phenolic resin construction.

Provided with the option to use PBSC’s control system, which integrates with the building access control system. Allowing proven software at FAT, reducing site time and risk.
