Manufacturer of Popular Rubber Band - Mechanical Seal Airtight Doors – Golden Door

BSL3  Mechanical Gasket Air Tight Sealed Doors
Mechanical Gasket Air Tight Sealed Doors for High Containment Facilities
Golden Door’s air pressure resistant mechanical  gasket air tight sealed doors for high level containment area for BSL3 laboratories and pharmaceuticals. This door creates a reliable airtight barrier with a sturdy, but pliable seal, which is compressed against the door frame.
The mechanical seal does not rely on compressed air to form a sealed closure. Therefore, the doors provide effective seals, even power loss.
The product features a user-friendly design using a steel arm to press the door into the seal.  The mechanism is fixed onto the doorframe, to avoid adding extra weight to the door itself.  The mechanical seal door requires a raised threshold to form an unbroken seal.  Where a flush threshold is needed, our pneumatic sea doors can be used instead.
Our mechanical seal doors are an effective solution for BSL3 or BSL4 laboratories, and other applications that necessitate a high level of containment.  The raised threshold means that the mechanically sealed doors are best suited to low traffic areas, where wheeled carts are not required.
