Fire damper (FHF, FHF-Y)
Product Introduction:
Normally open. Closes when the flue gas temperature inside the pipe reaches 70℃ during a fire, and can meet the requirements of opening volume and fire integrity within a certain time, playing a fire prevention role.
Product Parameters:
Nominal Pressure: ≤300Pa at ambient temperature;
Applicable Medium: Air (flue gas);
Leakage: a. At ambient temperature, the leakage per unit area with a pressure difference of 300±15Pa across the valve blade ≤500m3/m2.h;
b. Within the specified fire resistance time (GB/T15930), the leakage per unit area with a static pressure of 300±15Pa across the valve blade ≤700m3/m2.h;
Product Applications:
Suitable for industrial and civil buildings, subway, power plant ventilation, and air conditioning systems' supply and return air ducts.

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.
