Among the cooling fans used in air compressors, axial fans and centrifugal fans are common, and their main functions are both to ventilate the air in the environment. So what is the difference between an axial fan and a centrifugal fan, let's talk about the difference in detail below.
1. The appearance and shape of centrifugal fans and axial fans are different
This is an intuitive point. The axial fan, including the industrial axial flow fan, is basically cylindrical in appearance, while the centrifugal fan is snail-shaped or spiral-shaped.
2. The motor connection mode of centrifugal fans and axial fans is different
The motors of axial fans are generally connected inside the body of the fan, and the motors of centrifugal fans are connected by the shaft, so the motors of centrifugal fans are all outside.
3. The installation method of centrifugal fans and axial fans is different
The installation method of axial flow fans is generally relatively simple. For example, a small axial fan can often be seen installed on the wall at home. The installation method of centrifugal fans is more complicated, so I won't introduce it in detail here.
4. The air volume and pressure of centrifugal fans and axial fans is different
The air volume and pressure of the axial flow fans are relatively small, while the air volume and pressure of the centrifugal fan of the same fan diameter will be relatively large.
5. The exhaust direction of centrifugal fans and axial fans is different
The exhaust direction of the axial flow fan is straight along the axial direction. The exhaust direction of the centrifugal fan is perpendicular to the direction of the air inlet, so it can achieve air exhaust at multiple angles.
