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 is committed to becoming a leader in the High Efficiency YD Series Pole-Changing Three Phase Induction Motor Induction Motor industry, actively implementing a 'total quality management' system, and striving to achieve 'excellenct product and perfect service' based on the actual needs of customers. Since the establishment of our company, it has always been adhering to the corporate philosophy of 'symbiosis', with the goal of creating world-class products, and striving for diversification and globalization. We have the well-equipped machine, advanced technology, and strict quality management system. Excellent quality and good service enable us to win trust and reward in domestic and overseas.
