ZY SCREW's advantage: Welcome to contact us, Camille will reply you timely! Axial Flow Fan has a wide range of uses, that is, the airflow in the same direction as the fan blade's axis, such as the electric fan and the external fan of the air conditioner. It is called "axial flow" because the gas flows parallel to the fan shaft. Axial flow fans are usually used in situations with high flow requirements and low pressure requirements. The axial fan is fixed and moves the air. Axial flow fan is mainly composed of fan impeller and casing, with simple structure but high data requirements.
