12038 Small DC Axial Fan With Aluminum Frame

This series of fans consists of an aluminum alloy shell, asynchronous motor, single flange cylindrical shell, and fan blades. It has the characteristics of large air volume, low vibration, and low noise. The fan is mainly used for ventilation and heat dissipation in industries requiring large air volume, such as ground automatic control devices, large electronic equipment, cabinet, electric welding machine, and so on.

power：2.4W-10.56W
Air volume：76CFM-150CFM
Rotating speed：1800RPM-3500RPM
