Axial Flow Fan

It refers to the airflow in the same direction as the axis of the fan blade, such as an electric fan or an external fan of an air conditioner, which operates in an axial flow mode. The reason why it is called "axial flow" is 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 flow fan is fixed in position and moves the air.
