Description
BDW axial flow roof fann is mainly used for indoor ventilation and exhaust of large buildings such as petroleum, chemical, metallurgy, machinery, national defense, warehouses, theaters and restaurants. The gas to be transported does not contain viscous substances, and the dust particles contained are not more than 150 mg/m3, and the temperature thereof must not exceed 60 °C. There are seven models of roof axial fans, and the rotation forms are all electrical rotation. The fan is composed of an impeller, a wind cylinder, a top cap, an electric motor, and a rain cover.
The fan has stable performance, balanced operation and safe and reliable operation. The impeller is corrected by static balance, the vibration is small, the structure of the fan is reasonable, and it is easy to maintain.
The fan is installed in the roof section and does not need to be installed with ventilation ducts.
