Fans can be classified into several types based on the material used, such as iron shell fans (ordinary fans), fiberglass fans, plastic fans, aluminum fans, stainless steel fans, and so on.

Fans can be classified according to the direction of gas flow, including centrifugal, axial, and diagonal flow

Types such as mixed flow and cross flow.

(1) Centrifugal fan. After entering the impeller of the fan axially, the airflow mainly flows radially. This type of fan is made based on the principle of centrifugal action, and the products include centrifugal ventilation fans, centrifugal blowers, and centrifugal compressors.

(2) Axial flow fan. The airflow enters the impeller of the fan axially and flows approximately along the axial direction on a cylindrical surface. This type of fan includes axial flow fans, axial flow blowers, and axial flow compressors.

(3) Rotary fan. Using rotor rotation to change the volume of the air chamber for operation. Common varieties include Roots blowers and rotary compressors. Fans are divided into axial flow fans, centrifugal fans, and mixed flow fans based on the direction of airflow entering the impeller. Fans are classified according to their use into compression type local fans (hereinafter referred to as compression type fans) and explosion-proof motors placed outside or inside the flow channel. Explosion proof motors are placed in explosion-proof sealed chambers for extraction type local fans

Abbreviated as extraction fan）Fans can also be divided into single-stage, two-stage, or multi-stage pressurized fans according to the form of pressurization. If 4-72 is a single-stage pressurized fan, the fan is a multi-stage pressurized fan. Fans can be divided into axial flow fans, mixed flow fans, roof fans, air conditioning fans, etc. according to their purposes.

Fans can be divided into negative pressure fans, low-pressure fans, medium pressure fans, and high-pressure fans according to pressure.

Centrifugal fan: higher pressure but lower air volume.

Axial flow fan: higher air volume but lower pressure.

Mixed flow fan: The air volume and pressure are between centrifugal and axial flow fans. Cross flow fan: has high dynamic pressure and can obtain flat airflow.

(2) According to the different materials used, it can be divided into:; Iron shell fan (ordinary fan), fiberglass fan, plastic fan, aluminum fan, stainless steel fan, etc.

(3) According to the direction of gas flow, it can be divided into centrifugal, axial, mixed flow, and cross flow types.

(4) According to the direction of airflow entering the impeller, it can be divided into axial flow fans, centrifugal fans, and mixed flow fans.

(5) According to their purposes, they can be divided into: pressure type local fans and explosion-proof motors placed outside or inside the flow channel, and explosion-proof motors placed in explosion-proof sealed chambers as extraction type local fans.

(6) According to the form of pressurization, it can also be divided into single-stage, two-stage, or multi-stage pressurized fansThe above information is provided by the enterprise itself, and the authenticity, accuracy, and legality of the information content are determined by the relevant enterprise
