The design and function of centrifugal fan is quite different from that of axial fan. Their differences make them suitable for different applications, and customers sometimes don't know which fan type is suitable for their needs. The history of axial-flow fans can be traced back to the horizontal configuration of windmills in medieval Europe. An electric fan introduced by Dai is an axial-flow fan.
Axial fans are named for the direction of airflow they produce. The blades rotating around the shaft can draw in air parallel to the shaft and discharge the air in the same direction. Axial fans produce high flow, which means they produce a lot of air. However, the airflow they produce is low pressure. They require low power input to operate. The centrifugal fan was invented by military engineer Lieutenant General Alexander sablukov.
Centrifugal fans are usually called blowers, which are different from axial fans. The incoming airflow pressure is increased by the fan impeller (a series of blades mounted on a circular hub). Centrifugal fans move air radially - the direction of the air flowing outward is usually 90 ° from the direction of the incoming air.https://www.ck-stone.com/
