The main varieties of industrial centrifugal fans are diverse and each has its own characteristics. The following is an overview of some common varieties and their characteristics:

1、 Main varieties

1. Front jet centrifugal fan:

Gas enters vertically from the center of the impeller.

The air volume is relatively small and the pressure is low.

2. Rear jet centrifugal fan:

There is a nozzle behind the impeller, and gas is sprayed onto the back of the impeller.

Capable of generating high gas pressure and airflow, suitable for various ventilation, air exchange, and heating/cooling applications.

3. Pull type centrifugal fan:

Reverse design of impeller.

Suitable for handling gases with high concentrations of solid impurities, and can also be used for applications with high air flow velocities.

4. Diagonal flow centrifugal fan:

There is an angle between the impeller axis and the intake axis.

Improve gas flow efficiency, suitable for situations where gas flow efficiency needs to be improved.

5. Medium pressure, low pressure, and high pressure centrifugal fans:

According to the pressure range, medium pressure centrifugal fans are commonly used in air conditioning and ventilation systems; Low pressure centrifugal fans are suitable for keeping warm equipment in cold winter; High pressure centrifugal fans have strong processing capabilities and high requirements for noise and vibration, making them suitable for special occasions such as oxygen generation and hydroxide escape.

6. Axial flow centrifugal fan:

The blade belt has a spiral line at a 45 ° angle.

Handling low-pressure and high flow situations is the preferred choice for large ventilation and air conditioning equipment.

7. Rear tilting centrifugal fan:

Design with backward tilting of wind blades.

Uniform air volume, low noise, smooth airflow, suitable for local ventilation, explosion hazardous areas, kitchen smoke exhaust, etc.

8. Explosion proof axial flow fan:

The casing and fan impeller are made of soft metal.

Suitable for flammable, explosive gases or geographical environments.

9. Dust removal fan:

• Used for transporting high concentration dust gases.

The casing is wear-resistant and not easily blocked by dust, suitable for industrial equipment in pneumatic conveying systems.

10. Corrosion resistant centrifugal fan:

Made of corrosion-resistant materials such as stainless steel, plastic, or pottery.

• Used for transporting steam that corrodes metal materials.

2、 Common characteristics

• Efficient and energy-saving: Adopting efficient blade design to minimize energy consumption and improve ventilation efficiency.

Low noise: The noise generated during operation is relatively low and will not cause noise pollution to the surrounding environment.

• Easy maintenance: Modular design makes daily maintenance and upkeep easier and more convenient.

Corrosion and high temperature resistance: Using high-quality materials and anti-corrosion processes, it can resist chemical corrosion and operate stably in high temperature environments.

Strong adjustability: It can be adjusted according to different usage scenarios and needs, such as wind volume, wind pressure, and other parameters that can be infinitely adjusted.

In summary, there are various types of industrial centrifugal fans with their own characteristics, which can meet the needs of different industrial fields and specific application scenarios. When choosing, it is recommended to determine the most suitable variety and parameters based on the requirements of the actual application scenario.
