Product introduction
Product Description:
Fireproof Outlet (Normal Open) （FHK）
Usually it is open, once fire occurs, the gas temperature of duct arrives at 70°C, and then the fuse protector will be fused or driven by shape memory alloy, the valve will close under the effect of torisional spring force .When the temperature return to normal, the valve opens automatically.
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)Used as air vent to adjust air flow direction
(7)Surface plate is aluminum alloy
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.
