The smoke exhaust and fire damper is a kind of fire protection component. It is generally installed on the pipe of the mechanical smoke exhaust system. It is usually open. When a fire occurs, the smoke exhaust is turned on. When the temperature of the flue gas in the exhaust pipe reaches 280 degrees, it is closed. It can meet the requirements of smoke leakage and fire resistance integrity within a certain time, and play the role of smoke and fire resistance.

1. It is in an open state at ordinary times. In the event of a fire, when the temperature of the flue gas in the exhaust pipe reaches 280 degrees, it will be closed, and it will meet the requirements of smoke leakage and fire resistance integrity within a certain period of time, and play the role of smoke and fire resistance.
2. The valve can be closed by the DC24V power supply (electric smoke exhaust and fire damper).
3. Manual shutdown or manual reset.
4. DC24V electric reset after closing (automatic smoke exhaust and fire damper, suitable for places where manual operation is inconvenient).
5. Output valve closing signal, which can be interlocked with other fire protection equipment
