Axial fans are air flow in the same direction as the axis of the blades. For example, electric fans and air conditioner fans are fans operating in axial flow. It is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are usually used in occasions with higher flow requirements and lower pressure requirements. Axial fans can be divided into steel fans, anti-corrosion fans, PVC fans and stainless steel fans. Ordinary axial fans can be used for ventilation in general factories, warehouses, offices, houses, etc., and can also be used for forced ventilation of air coolers (air coolers), evaporators, condensers, etc.
