Marine fire damper is equipped to ventilation pipes which can prevent fire accident. We have three types: Automatic type (Manual type), Electric type and Pneumatic type for round and rectuangular fire dampers. Stainless steel material is optional according to owner requirement.

Automatic type: Damper opens manually, close by dragline. When ambient temperature reaches 70±2ºC, blade will action automatically to close the damper.

Electric type: Damper opens by electric, close can with three ways:
1)  cut off the air supply on the spot,
2)  remote control center to control,
3)  when ambient temperature reaches 70±2ºC, blade will action automatically to close the damper.

Penumatic type: During operation, the compressed air is sent to the cylinder through the hand valve, the solenoid valve and the jogger valve to push the piston move, then fire damper opens. There are three ways to close:
1)  when ambient temperature reaches 70±2ºC, the damper pin actuates to cause the jogger valve to cut off the air supply
2)  Pull the hand valve to cut off the air supply
3)  Use remote control center to control the solenoid valve and cut off the air supply.
