What Is The Difference between Axial Fan And Centrifugal Fan

In the industrial and commercial fields, fans play a very important role. At present, the two common types of fans are axial flow fans and centrifugal fans, but many people can't tell what the difference between them. And how to choose the fan that is more suitable for application? Today, let's take a look at what is the difference between axial fans and centrifugal fans?

Axial fans vs Centrifugal fans

1. Working Principle

The axial fan drives the blade with the motor to make the air flow along the axis. The blade is connected with the motor rotor and rotates with the motor rotation.

Centrifugal fans rotate the impeller driven by a motor, so that air enters the impeller and is thrown out by centrifugal force, and the impeller is usually located outside the fan and connected to the motor rotor.

2. Performance Characteristics

Axial fan has the characteristics of high ventilation volume, low ventilation resistance, compact structure, high gas compression ratio, and remote air supply, which is suitable for places with large air volume demand and limited space.

The centrifugal fan has the characteristics of high static pressure, stable air supply effect, large ventilation volume and low noise, and is suitable for occasions with high noise requirements.

3. Application

Axial fan is suitable for large air volume and medium air pressure or remote air supply occasions, such as factories, commercial places, agricultural greenhouses, subway stations, large shopping malls, etc.

Centrifugal fans are suitable for places that require stable air supply effect and high wind pressure, and have high noise requirements, such as industrial processes, purification projects, hospitals, libraries, etc.

Through these characteristics, I believe that we have clearly understood the difference between axial flow fans and centrifugal fans, so what else need to pay attention to when choosing, in order to choose a more suitable and durable fan?

4. Choosing skills of fans

Choosing the right fan, you can get twice the result with half the effort, we can choose according to the actual needs and application occasions, the following skills you can understand:

1).Determine the required air volume, wind pressure and noise requirements

2).Check the structure of the fan is compact and durable

3).Confirm the brand and power of the fan and after-sales service

4).Check the fan control system
