FT30C (BFT30C) type axial flow fan, the series of fan impeller and outer casing are made of FRP composite material. The utility model has the advantages of simple structure, low noise, convenient installation, good anti-corrosion performance, high static pressure and high efficiency, stable operation and reliability. It is mainly used for ventilation and ventilation in the pickling section, laboratory, and basement with corrosive gas. It is also suitable for ventilation in general workshops, warehouses, office buildings, residences, etc. BFT35 can transport all kinds of corrosive gases with inflammable and explosive gases. The content of hard particles or dust in the gas to be transported is ≤150mg/m3, and the temperature should not exceed -20°C to 80°C.
Structure and features:
This series of fans is mainly composed of impeller, casing and motor.
Impeller: Made of fiberglass.
The casing is composed of a wind cylinder and a bracket. The air cylinder is a gap between the glass fiber reinforced plastic cylinder and the impeller, and the bracket is made of a profile and connected to the air cylinder.
Motor: The FT30 fan is equipped with a motor for the axial fan of the same power, and the BFT30 fan is equipped with an explosion-proof motor. It is also possible to use the same motor for axial flow fan of the same power as the user needs: YSF (YBF) series motor.

The series of fans have high aerodynamic efficiency, low noise and strong anti-corrosion and explosion-proof.
