Fire Damper (FHFK)
Product Introduction:
Fire dampers are installed at the end of ventilation and air conditioning systems with fire protection requirements. When a fire occurs and the temperature in the system pipe reaches 70℃, the damper will close, isolating the fire source at the supply and exhaust air vents.
Product Parameters:
Nominal pressure: ≤300Pa at ambient temperature;
Applicable medium: Air (flue gas);
Leakage: a. At ambient temperature, with a pressure difference of 300±15Pa across the valve blade, the leakage per unit area is ≤500m3/m2.h;
b. Within the specified fire resistance time (GB/T15930), with a pressure difference of 300±15Pa across the valve blade, the leakage per unit area is ≤700m3/m2.h;
Product Applications:
Suitable for the supply and exhaust air vents of ventilation and air conditioning systems in subways with fire protection requirements

Metal shell (chip, array type) muffler
This type of silencer consists of silencing elements, a metal outer shell frame, internal support components, and connecting components. The silencing elements and shell plates are modular and assembled on-site. They can be quickly disassembled and reassembled, making disassembly and assembly convenient and facilitating maintenance and repair.
-
Structure (chip-type, array-type) silencer
This type of silencer uses bolts to connect the silencing plates to the internal support, forming an integral structure. It can be assembled in a vertical shaft (vertical installation) or on a horizontal air duct (horizontal installation). The assembly process is simple and installation is convenient.

Pipeline silencer
This type of silencer is an integral structure, composed of silencing plates, a metal shell, and flanges.
-
Electric motorized damper
This valve can be electrically opened and closed, and the air volume can be adjusted.
