Centrifugal fan is to rely on the input of mechanical energy, increase the gas pressure sending gas machinery side by side, it is a follower of fluid machines. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation, dust and cooling ventilation of boilers and industrial furnaces and air air conditioning equipment and household appliances and equipment for cooling and ventilation; grain drying and organization; wind tunnel air and hovercraft inflatable and push, and so on.

Centrifugal fan based on principle of the kinetic energy into potential energy, high-speed rotating impeller the gas to speed up and slow down, change direction, convert the kinetic energy into potential energy (pressure). Single-stage centrifugal blower, gas from entering the impeller axially, gas flowing through the impeller into radial, then into the diffuser. In the diffuser, changed the direction of flow gas and pipeline section increasing flow deceleration, the slow conversion of kinetic energy into pressure energy. Increased pressure mainly in impeller, then occurs in the diffusion process. Multistage centrifugal blower, back flow into the next impeller, higher pressure.
