(2)Certificates of Invention Patent
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 has a strong market position, we can produce customized 180W 6 Pole Direct Drive Blower Motor Can Be Customized to meet the needs of customers at home and abroad. We are aimed to build branded products and provide users with a good experience, hoping to shape our corporate image by continuously improving our professional level. We provide our clients with sustainable and stable investment returns on a sound basis.
