Product details
Fire air valve is mainly used for fire safety requirements of the ventilation system of wind pipe, when fire, once the wind tube temperature rose to more than 70 DEG C, fire air valve quickly and automatically shut down, to achieve regional isolation to prevent fire along the duct and spread, control using Belimo actuators; the fire damper design is according to sea can effectively blocking water vapor, smoke seeps, ensure the work under this kind of environment, especially suitable for humid environment of ship, offshore platform and underground engineering. Fusing temperature 70 + 3 Closing time < 2S - the air leakage is less than or equal to 5m3/m2 - H Control the power supply DC24V/AC110V/AC220V, 50/60Hz Electrical protection class IP55/IP56 Explosion proof grade ExdIIBT4/ExdIICT4 Fire rating A0~A60 Fire damper is mainly used for ventilation, air conditioning system wind pipe, usually in the "normally open" state, when the air temperature reached 70 degrees Celsius, through the wind valve fuse action automatically closed. Widely used in various types of passenger ships, cargo ships, ships and offshore oil platform and the air duct.
