FRP roof fan has low noise and low vibration. The shell is treated with the latest anti-corrosion process by thermal spraying, which is highly resistant to humidity and atmospheric corrosion, which can ensure the stable operation of the fan under outdoor conditions. It is suitable for forced ventilation of modern building design such as electric power, petroleum, chemical industry, metallurgy, warehouse, etc.
The fan is installed vertically on the roof, and there is a mushroom-shaped hood with rain and snow. It is also equipped with a loose-leaf damper that can be automatically opened. When the fan stops running, the damper is closed to reduce the indoor heat loss in the season. The mushroom-shaped hood and case are made of FRP. The hood and the casing can be removed and separated for easy installation and maintenance. The impeller is directly connected to the motor. The glass fiber reinforced plastic airfoil blade is used to make the fan have good aerodynamic performance. The working medium of the fan is an industrial atmosphere. Temperature 55 ° C). When the medium temperature is 25 ° C, the relative humidity does not exceed 95%, and the dust content (including solid impurities) of the medium should not exceed 100 mg / m3.
