We are offering MS Air Damper to our clients. Kaizen Airtech provides volume control damper design vertical or horizontal wall mounted. The smooth “butterfly” action of two pivoting blades provides continuous adjustment. Kaizen Airtech damper is conveniently adjusted from the room side of the diffuser. The damper is constructed with MS powder coated or GL powder coated. Usually, the damper is open. When the fire occurs, the fuse plug promptly closes automatically. Manually open the damper to reset the system. Damper open rate is small when the temperature is lower, when the temperature rises, the requirement of heat radiation is high, and the damper will open large. The damper will open 100% when the temperature reaches to fully open temperature.
