According to the wind of subsection
According to the pressure of the fan, the fan can be divided into low-pressure fan, medium pressure fan and high pressure fan.
Air blower
Air blower
The pressure range is as follows:
Low pressure: the total pressure of the fan is less than 1000 pa
Medium pressure: 1000Pa < H = 3000Pa
High pressure (centrifugal fan) : 3000Pa < H = 15,000 Pa
Low pressure and low - pressure fan are used in ventilation engineering.
Can be divided into centrifugal fan and axial flow fan and water treatment blower;
Hospital and laboratory sewage mixing aeration;
Vacuum delivering paper in the printing industry;
The stirring aeration of electroplating bath and industrial wastewater;
Supply of plastic welding and blowing air;
Sprays of burners, glass industries and others;
