Structure and performance characteristics:

1. Compact and beautiful structure. The box body is assembled by frame and box board. The frame adopts domestic advanced metal cold bending into a unit for one-time stretching, and the fan adopts a joint design to further reduce noise.

2. Provide different import and export directions, motor position to meet different installation needs of users. It adopts mold production and has high dimensional precision. It can be assembled after disassembly.

3. The main components of the fan are all moulded. It is characterized by high efficiency, low noise, large air volume, stable operation, stable quality and durability. The volute is made of high quality galvanized sheet and mechanized.

4. HTFC series centrifugal fire exhaust fan (centrifugal fan) is divided into A, C and B types. A and C motors are installed outside the box for fire and smoke exhaust; B type motor In the box body, used for ventilation and ventilation.

Conditions of Use:

The requirement for conveying gas during use: no corrosive gas, no viscous substance in the gas, and no more than 150mg/m3 of dust and hard particles. The built-in fan of the motor is suitable for general ventilation and ventilation; the external fan of the motor can be used for both general ventilation and fire evacuation, and can be continuously operated for more than 30 minutes under the condition of 280 °C.
