Air Tight Doors "Airef" make Air Tight Doors are single/double wing doors to stop the advance of contaminated air into the protected area. The air tight doors, already manufactured by us, have been designed for air tightness at a pressure of 2500 Pascal. The doors are fabricated out of structural steel. The door frame is designed for easy installation in the reinforced concrete wall. Door hinges are provided with maintenance free slide bearings or roller bearings.

The sizes of the door can be as per requirement and the same can be either manually or automatically operated with the help of Pneumatic/Hydraulic/Electric mechanisms.
