Mechanical Seal APR Doors

What is the QUALIA's Mechanical Seal APR Doors?

The mechanical Seal APR Doors is a specialized containment solution designed for biosafety areas. Its mechanical sealing mechanism maximizes the seal between the door leaf and frame, preventing contaminants from entering or leaving the controlled zone. This door’s locking system could operated manually or automatically, exerts pressure against the frame when closed, creating a highly secure seal. Such doors are deployed in biosafety laboratories, pharmaceutical facilities, medical centers, and other environments requiring stringent control, like P3 and P4 level labs, ensuring optimal biological and chemical isolation between different areas.
