Product Description

OKM Air-/Gas-Tight Door blocks air flow in-between compartments and is designed to be completely air-tight. Gasket packing system do good in preventing contaminated air from entering a clean area. The Air-/Gas-Tight Door is installed as a door in the region between a liquid contaminated area and a gas contaminated area, between a gas contaminated area and an air-tight room, between an air-tight room and a non-harmful zone, and a clean machine room and a contaminated machine room.

It  is also installed in the inside of the blast-proof door connecting a non-harmful zone to the outside. The door runs freely against positive pressure and negative pressure. It can resist considerable pressure and is designed to be opened inward. This door makes it possible to maintain air tightness allowing one to push and open it when the indoor air pressure spikes up. It is also perfect for use as a main entrance door in conjunction with the blast-proof door.

The Air-/Gas-Tight Door must meet the prescribed air leak standard (N S3206 STANDARD): less than 0.5cmh per door of 1 under 800. The doors use stainless or iron materials and the flaps and frames of the doors are secured on steel surfaces with epoxy or urethane paints to prevent contamination.

The company carries out tightness performance tests in its basic evaluation course during manufacture and delivery, and the Korea Institute of Machinery and Materials, a national official accreditation institute, conducts the evaluation and certification operations upon request. The company is currently working to maximize the technologies related to this doors production by acquiring the patent on tightness structure (Patent No. 0530239).

The door body is made of colorized steel/alluminum alloy sandwich board with foaming process (small window with Double glass to realize visual the airproof function.) It also can be made of the large-plane 304^# stainless steel plate and framed large-plane glass. The inner material is usually polyvinyl chloride foam panel. The inner material also could be asbestos which make the door fire-proof. The dimension of the door is decided by the door hole and there is no standard dimension for it.
