The high-speed fan is kept at a safe distance from the user thanks to our Motor Fan Blades And Covers range. It shields the motor fan, which is often made of plastic, from being damaged by external objects. To maximise convection cooling, the provided range deflects air flow toward the stator fins rather of directing it in a radial direction, as is typical for motor fan designs. The marketed Motor Fan Blades And Covers range help to keep a motor or other device at the proper operating temperature.
