The reason why the blower can drive the gas circulation movement is caused by its structural design and functional characteristics. When the impeller inside rotates, because of the centrifugal force, the vane will promote the gas forward and outward movement, thus forming a series of spiral motion.

This causes the air between the blades of the blower impeller to spiral and spin faster, eventually forcing gas from outside the device into the side slots. When it enters the side channel, the gas is compressed and then returned to the impeller blades to accelerate the rotation again. As the rotation progresses, the kinetic energy of the gas increases, further increasing the pressure of the gas passing along the side channel.

When the air reaches the connection point between the side groove and the discharge flange, the air is forced out of the blade and discharged through the outlet. It is so that the blower has the dual function of blowing and sucking, and can be used for both purposes. Although it has certain details with similar fans, its advantages are also very obvious, such as low noise of operation, maintenance-free use, very small mechanical wear and so on, which broadens its range of use.
