Axial flow fan and centrifugal fan are two different products in the fan category, and their main function is to ventilate the air in the environment.
1. Axial flow fans are widely used, that is, the air flow in the same direction as the axis of the fan blade, such as electric fans, air conditioning external fans are axial flow fans. The reason why it is called "axial flow type" is that the gas flows parallel to the fan axis. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. The axial flow fan fixes the position and moves the air. Axial flow fan is mainly composed of fan impeller and casing, with simple structure but high data requirements.
2. Centrifugal fan is a kind of driven fluid machinery, which depends on the input mechanical energy to increase the gas pressure and discharge the gas. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; Ventilation and induced draft of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grain; Wind source of wind tunnel and inflation and propulsion of hovercraft.
