Centrifugal fan application
- Industrial Manufacturing: Centrifugal fans are used in many industrial environments, such as steel metallurgy, chemical industry, mining, etc. In these industries, fans are usually used to strengthen air supply, exhaust, refrigeration and hot air systems. Especially in harsh environments such as high temperature, corrosion, dust, etc., centrifugal fans play an irreplaceable role.
- Environmental protection equipment: Centrifugal fans are also widely used in environmental protection equipment, such as sewage treatment, exhaust gas purification, etc. At the same time, centrifugal fans also play an important role in dust removal equipment, incineration equipment and advanced physical noise reduction equipment.
- Construction Equipment: In the construction field, centrifugal fans are used in air conditioning, ventilation, hot air and other fields. Through the air supply and exhaust system, they realize the circulation and flow of air and promote the convection and ventilation of indoor air.
- Temperature control: Centrifugal fans can change the ambient temperature by blowing air, so they have important uses in heating, ventilation, air conditioning, drying and other temperature regulation equipment.
- Air purification: In special environments such as laboratories, operating rooms and other places that have strict requirements on air quality, centrifugal fans can be used for air filtration and purification.
- Agricultural cultivation: In agricultural production, centrifugal fans are used to provide a stable air environment for greenhouse plant growth, animal feeding, etc.
- Transportation equipment: In transportation equipment such as trains and ships, centrifugal fans are also used for air circulation.
- Food Processing: In the food processing industry, centrifugal fans are also very commonly used, such as drying equipment, cooling equipment and other food processing technology equipment.
- Other occasions: Centrifugal fans are widely used in heating, fresh air systems, exhaust systems and many other fields.

Centrifugal fan working principle
- The working principle of the centrifugal fan is to use a high-speed rotating impeller to accelerate the gas, and then rely on centrifugal force to push the gas from the suction side to the discharge side. Specifically, when the impeller rotates, the gas is sucked into the impeller. As the impeller rotates, the gas leaves the impeller in the radial direction under the action of centrifugal force, thereby pushing the gas from the suction end to the discharge end.
The structure and function of centrifugal fans
- The centrifugal fan is mainly composed of impeller, casing, main shaft and coupling. The impeller is the main component that generates wind pressure and transmits energy. The casing is used to introduce and discharge gas. The coupling is used to connect the motor and fan to transmit torque. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings.
Types of centrifugal fans
- Classification by impeller structure:
- Forward centrifugal fan: The rotation direction of the impeller is the same as the direction of gas flow, suitable for low flow and high pressure situations.
- Backward centrifugal fan: The rotation direction of the impeller is opposite to the direction of gas flow, and it is suitable for high flow and low pressure situations.
- Radial centrifugal fan: The impeller blades are arranged in a radial pattern and are suitable for medium flow and medium pressure applications.
- Mixed-flow centrifugal fan: combines the characteristics of axial flow and centrifugal fans, and is suitable for medium flow and medium pressure applications.
Classification by use:
- Industrial centrifugal fans: widely used for ventilation and dust removal in factories, mines, tunnels and other industrial places.
- Household centrifugal fan: used for cooling and ventilation in air conditioning equipment and household appliances.
- Special purpose centrifugal fan: used for special purposes such as wind tunnel wind source and hovercraft inflation.
centrifugal fan application
Classified by airflow direction:
- Unidirectional flow centrifugal fan: The air flow has only one inlet and one outlet, suitable for simple ventilation systems.
- Bidirectional flow centrifugal fan: With two inlets and two outlets, it is suitable for occasions requiring two-way ventilation.
Classification by driving method:
- Electric centrifugal fan: driven by an electric motor, suitable for most applications.
- Gas-driven centrifugal fan: driven by a gas engine, suitable for occasions without power supply.
Classification by noise control:
- ow-noise centrifugal fan: Designed with noise control in mind, it is suitable for occasions that require a low-noise environment.
- High Noise Centrifugal Fan: Suitable for occasions where noise requirements are not high.
