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.
Our company always leads the trend with first-class quality, and makes unremitting efforts to build the first brand of Mv300/3m Single Phase 2 Poles Construction Concrete Vibrator Motor. Our corporate culture contains lofty ambition, strong will, down-to-earth action, and a high degree of condensation of personality. Our spirit of pursuing excellence reflects the enterprise requirements of maintaining innovation, continuous improvement, emphasizing efficiency and focusing on benefits.
