Features:

1.Marine pneumatic fire dampers can be made of materials such as carbon steel, stainless steel 304, stainless steel 316L, etc.

2.When the temperature inside the tube reaches 70 ± 3 ° C, the temperature fuse will melt and the air damper will automatically close;

3.After the compressed air is connected to the air damper, the air pressure is 0.5~0.8Mpa, and the air damper opens; After the air is cut off, the air brake is closed.

4.Pneumatic fire dampers can also be equipped with solenoid valves to electronically control whether to ventilate the dampers.
