The forward curved and backward curved centrifugal fans are different from the blades of the assembled fan. The forward curved type is generally called the blower, and the backward curved models are generally called the induced draft fan. The difference is the length of the impeller rung and the impeller edge.

Forward curved fan is parallel to the edge of the impeller. The impeller outlet Angle greater than 90 degrees is the forward impeller, also known as the forward impeller. The forward impeller is mostly high pressure. Backward and impeller are not parallel, the length to the impeller edge difference of a few centimeters or a few millimeters, refers to the impeller outlet Angle less than 90 degrees for the backward impeller, also known as the backward curved impeller, the backward impeller is mainly based on medium pressure.

There are three main differences

1) power

The static pressure head used to overcome the resistance of the system, the forward centrifugal fan is smaller than the backward centrifugal fan. Since the channel in the backward blade fan is gradually expanded, its hydraulic loss is smaller than that of the forward type. Therefore, the efficiency of forward centrifugal fan is lower than that of backward centrifugal fan.

(2) the energy consumption

Since the efficiency of the forward centrifugal fan is lower than that of the backward centrifugal fan, its power consumption is greater than that of the backward centrifugal fan.

(3) noise

The operation noise of the forward centrifugal fan is greater than that of the backward centrifugal fan.

Whether it is forward curved or backward curved centrifugal fan, it has its own advantages and disadvantages and the application of the corresponding scene. engineers will make the perfect match according to your actual use. Quick selection and quotation.
