Made in China Fire Vents Support Customization

Customized products are produced according to customer requirements. The working principle is to use the temperature control of fusible alloy to close the valve under the action of gravity and spring mechanism. In case of fire, the flame will invade the air duct, and the high temperature will melt the fusible alloy on the valve, or deform the memory alloy to make the valve automatically close. It is used for the occasion where the air duct runs through the fire compartment, and is installed at the inlet and outlet of the air supply and exhaust outlets of the ventilation and air conditioning system with fire protection requirements. The fire vent is composed of aluminum alloy vent and thin fire damper, which is normally open. Technical indicators: manual opening, manual or 70 ºC temperature control closing/five gear air volume adjustment. The control valve is installed on the valve head
Normally open, the fire control room displays the opening and closing status of the valve, with electric signal closing and manual valve body closing functions, 70 ° C fuse closing, and air volume regulation functions
