Speaking of the centrifugal fan, we would have to pay attention to the two important parameters, speed and air volume of equipment, there is inevitable connection between them. In order to better understand the relationship between the speed and volume of the centrifugal fan, we can analyze through experiment.

First, it is clear that the centrifugal fan air volume represents the equipment’s ability to complete ventilation and cooling, there are many reasons for the impact factors, including the speed of centrifugal fan, and the centrifugal fan speed is not unchanging.

We know the centrifugal fan realize working through the rotation of the blade, which a certain volume of air transfer out, different types of centrifugal fan air volume are not the same, but also different from the speed of the relationship.

An experiment was conducted to verify the following point, using two units of same centrifugal fan, and the speed of adjustment is then broken in one high and one low; exhaust fitted with a pressure gauge, while running in the same environment, observe the two centrifugal fan air volume which will be more?

In fact, the result is obvious, the higher the speed, the ability of air forced transportation of centrifugal fan is stronger, the centrifugal fan air volume is also bigger. 

Although the centrifugal fan air volume will be affected by other factors, but it is certain that the speed is certainly one of the important factors, and the two are in direct proportion to each other, the greater the speed, the centrifugal fan air volume will be greater.
