It includes fire damper, smoke damper, regulating damper and air supply outlet.
When a rise in temperature occurs, the fire damper closes. Usually activated by a thermal element which melts at temperatures are higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades.
Regulating damper is applied to adjust air volume, and air supply outlet is used to provide fresh air.
Application:
Apply in pipeline and duct of ventilation system.
Features:
- Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.
The flange is bended directly by the frame.
The valve size and color can be customized.
Duration, long service life.
- Easy installation.
Advantages:
- Excellent quality control processes, all products have been inspected strictly.
- The quality of products has reached the standard of “Code of acceptance for construction quality of ventilation and air conditioning works" (GB50243-2002) and "Fire dampers for building venting and smoke-venting system" (GB15930 2007).
- Complete accessories production and distribution make it easier to install.
