Radial Backward Centrifugal Fan High Efficiency For Cooling Systems

Backward curved radial blower fan with high efficiency used for cooling systems

Backward curved blower impeller, in the radial section of the impeller, the blade lateral line and the blade of the point of rotation direction of the tangent between the Angle is acute, that is, the back bending impeller, its obvious feature is the installation direction and the direction of rotation of the impeller is opposite.

The backbending impeller has high speed, large air volume and low pressure, but high efficiency. The centrifugal fan of the backbending impeller in China can achieve 80%-90% efficiency, which is widely used and not easy to scale and overload.
