Description

Fire hydrant

Manual HVAC fire damper , installed in the ventilation or air-conditioning systems, usually it is open, once fire occurs, the gas temperature of duct arrives at high degrees, and then the fuse protector will be fused and the damper will close under the pull of spring. It can meet the requirement of stability and completeness in a certain time. It can insolate smog and fire outside.

Mechanical dampers shut the cross sectional area of a duct in the event of a fire either by means of pivoting a fire-resistant board (in Europe), or by means of steel shutters, similar to blinds on a window (in North America). In the European designs, the turning mechanism is fully contained, permitting the dampers (subject to type approval) to be grouted in place, which permits a heat sink effect to conduct heat from an accidental building fire, which impinges upon a duct and damper, to be conducted into surrounding structures.
