It can meet the requirement of stability and completeness in a certain time. It can insolate smog and fire outside.

Application of ventilation aluminum air volum control damper:

Used in through-wall pipes of ventilation system, which need to be fireproofing

Features of Adjustable round air damper:

l Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.

l Duration, long service life.

l Easy installation.

l The flange is bended directly by the frame.

l The valve size and color can be customized according to customer's requirements.

l By DC24V power to close the valve

Advantages of Adjustable round air damper:

l Excellent quality control processes, all products have been inspected strictly.

l 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).

l Complete accessories production and distribution make it easier to install.
