HVAC Fire Dampers

Fire hydrant * Manual control type * Normally open, the valve will close after the break-down of fuse when the temperature reaches high degrees , stop the smoke to extend along the air duct. * It can work as a volume control damper when open to adjust the air volume. The blade is reset by manually.

Fire Damper Fire dampers are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors. Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures

Fire Damper Application: Used in through-wall pipes of ventilation system, which need to be fireproofing to prevent the spread of fire along the duct.

Fire hydrant 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.

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

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
