Plenum galvanized steel electronic air vent diffuser damper in hvac

Usually it is open, manually adjust the leaf opening at the range of 0-90 degree .When the temperature of flue gas in the pipeline reach 280 degrees, the fuse protector will be fused, and damper closes under the pull of spring.

Application:

Applied to the pipeline of smoke exhaust system and the entrance of smoke exhaust fan

Features:

1. Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.
2. Duration, long service life.
3. Easy installation.
4. The flange is bended directly by the frame.
5. The valve size and color can be customized according to customer's requirements.
6. Output closing signal according to customer's requirements.

Advantages:

1. Excellent quality control processes, all products have been inspected strictly.
2. 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).
3. Complete accessories production and distribution make it easier to install.
