Centrifugal fan is a type of fan with relatively high power, which is why it can be applied in many fields. So some people may ask, what is the basis for such a centrifugal fan to smoothly increase efficiency?

It's actually quite simple. The so-called centrifugal fan is just one form of fan. The reason why it can achieve so much power is largely due to the impeller of this type of fan. The so-called impeller refers to the fan blades that we usually see in a fan. Many people mistakenly believe that the good conclusion of a fan is because its speed is relatively fast. Not bad, the success rate of the fan's operation is directly related to its rotational speed.

But impellers are a relatively energy-saving measure that can reliably use the same amount of electricity while increasing efficiency. The conclusion that impellers can perform well in centrifugal fans has two aspects, one is the diameter of the impeller, and the other is the degree of inclination of the impeller.

If the diameter of the impeller is relatively large, it means that the model of this centrifugal fan is large enough. So the power will smoothly increase, which is also why fans with higher power tend to have larger volumes.

Another factor is the inclination degree of the centrifugal fan impeller. If the inclination degree is relatively small, the power will be relatively low. On the contrary, if the inclination degree is large, the power of the centrifugal fan will increase. But this is also within the range, because after all, the inclination of the impeller cannot reach 90 degrees, and most of them are within an acute angle. Otherwise, this centrifugal fan will have a shorter lifespan in terms of the impeller.  

So, if you want to increase the conclusion rate of a centrifugal fan at the same current, the only way is to improve the impeller of the fan.
