Containment You Can Rely On – High Containment APR Doors

PBSC’s High Containment APR Doors…

PBSC’s High Containment APR Doors / Mechanical Seal doors 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.

Our Mechanical Seal Door Sets work for all containment applications, with stainless-steel and machined HPL door leaves as options. Both door leaves are tested up to 2500PA (10” W.G.). The door set can be connected to an access control system if required.

The door frame features a stainless steel arm that can easily compress the combed edge against the seal. This mechanical mechanism is installed within the frame, which ensures that the door is lighter and easier to maintain.


  • Easy One-handed operation, with 3-point compression
  • The mechanism is mounted in the door frame for a more robust design
  • Stainless steel or solid core door HPL leaf
  • Flush glazing to both sides of the door leaf
