The FRP vertical axial flow fan is a special exhausting device for the paper machine in the paper industry. It can also be used in other industries and is an ideal equipment to eliminate hot and humid gases. The fan has a large air volume and wind pressure range and can be used as an input gas or as an output gas. The fan has acid, alkali and corrosion resistance, stable operation and low noise. The medium temperature delivered ranges from -60 degrees Celsius to +80 degrees Celsius.
The fan is a vertical installation, the motor is driven by a belt outside the casing, and the blade is a FRP twisted wing blade, which is 12 pieces, and the installation angle is 20°, 25°, 30°, 35°.
