PBSC’s APR Mechanical Seal doors for high containment facilities are designed to create a reliable airtight barrier. This is achieved by using a robust yet flexible seal that is manually compressed against the doorframe. The seal doesn’t need compressed air, making it a fail-safe option in case of a power outage.

Creating a dependable airtight barrier...

Our range of mechanical seal doors are ideal for high-containment applications, especially in BSL3 and BSL4 labs. These doors have a raised threshold that creates a natural bund, aiding in the containment of liquid during washdown.

Access Control - The access control system for building entrances is managed through a PBSC control panel, which can be requested if required.

PBSC's Mechanical Seal Door is also known as a High Containment Door, Hospital Door, Lab Door, Laboratory Door, Stainless Steel Door, APR Door and Cleanroom Door.
