Axial Fans

Axial fans are actually named as such because of the direction of the airflow that the fan creates; fan blades rotate around an axis, forcing air out parallel to the axis. The blades of the fan spin around a central shaft, creating a difference in air pressure that provides the suction needed to move the air through the fan. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the number and shape of the blades. Fans have many applications including in engine rooms, wind tunnels and cooling towers. Design parameters include power, flow rate, pressure rise and efficiency

Axial fans have a high flow rate, but the airflow it creates has low pressure. Axial fans work well for applications where a lot of air needs to be moved around. They require a lower amount of power to run than a centrifugal fan type
