Production details 

Difference between forward centrifugal fan

(1)efficiency: the efficiency of the forward leaning centrifugal fan is lower than that of the backward leaning centrifugal fan.

(2)energy consumption: because the efficiency of the forward leaning centrifugal fan is low, its natural consumption for electric energy is greater than that of the backward leaning type.

(3)noise: when the forward leaning centrifugal fan is in operation, the noise emitted by the forward leaning centrifugal fan is larger than that of the backward leaning fan.
