Electric Motorized 70 Degrees Fire Flaps And Dampers AC380V 3A Micro Switch

Detailed Product Description
Fire hydrant
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.
