Quiet Backward Centrifugal Fan Stainless Steel For Cement Plant

Backward curved blower quiet centrifugal fan with high efficiency used for cement plant

Three points different for backward curved blower and forwards curved blower fan:

(1) power

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

(2) the energy consumption

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

(3) noise

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

Whether it is a forward tilt or a backward tilt centrifugal fan, it has its own advantages and disadvantages and the application of the corresponding scene. The new Yongan fan will be perfectly matched according to your actual use.
