CFH-Q Type Marine Pneumatic Fire Damper
1. Features:
- The fire damper should normal open on getting compressed air & electric power, and should be close on loss of compressed air or electric power, pneumatic operating pressure is 0.5~0.8Mpa.
- If the temperature of air in damper duct exceeds 70±3°C, the fusible link of fire damper will be broken and the change valve will cut off the compressed air source to close the fire damper.
- On/off status of control electric source for solenoid change valve could be controlled locally or remotely, thus open/close the fire damper;
- Manual change valve can be controlled by handle drag line, and the fire damper can close locally or remotely.
- On/off signal output when the fire damper is on/off.
