Fans can be divided into various types according to different classification standards

Classified according to the flow direction of the airflow after entering the impeller:
Centrifugal fan: the airflow enters the impeller of the fan axially and mainly flows along the radial direction. This kind of fan is made according to the principle of centrifugal action, and is often used in occasions where higher pressure and smaller flow are required.
Axial fan: The airflow enters the impeller of the fan axially and flows along the axis on the cylindrical surface approximately. Axial flow fans have the characteristics of large flow, small size and low pressure head, and are often used in occasions that require large flow and low pressure.
The diagonal flow (mixed flow) fan: the direction of the airflow is between the axial flow and approximately flows along the cone. The pressure coefficient of this fan is higher than that of the axial flow fan, and the flow coefficient is higher than that of the centrifugal fan. It is suitable for occasions that require medium pressure and flow.
Classification by material used:
Such as iron fan (ordinary fan), glass steel fan, plastic fan, aluminum fan, stainless steel fan, etc.
Classification by purpose:
Such as press-in local fans, extraction local fans, roof fans, air conditioning fans, etc.
According to the form of pressure classification:
Such as single-stage pressurized fan, two-stage pressurized fan or multi-stage pressurized fan.
Classification by pressure:
Such as low pressure fan, medium pressure fan, high pressure fan.
Classification by outlet pressure (boost):
Such as ventilator (≤ 15000 Pa), blower (1.5~350000 Pa), compressor (≥ 350000 Pa).
