PBSC’s high containment APR door set features a flexible seal that securely compresses against the doorframe, ensuring a reliable airtight barrier.

Our door set comes in your choice of stainless steel or machined HPL door leaves. Both options have been tested to withstand 2500PA (10″ W.G.). The door set can be connected to an access control system if required. To ensure a tight seal, we use a stainless steel arm to compress the combed edge of the frame against the seal. Our mechanical mechanism is mounted in the door frame, reducing the weight of the door and improving maintenance.
