Sewage Backwash Multistage Centrifugal Blower, aluminum impeller, pressure 80KPA
Working principle: During the rotation of impeller, due to the effect of rotating centrifugal force and working round diffuser flow, the speed of the gas is increased, and then convert the velocity energy into pressure energy. Multi-stage centrifugal blower has several groups of impellers on its main shaft, air is compressed by the multiple groups of impeller gradually.
D series multi-stage centrifugal blower can be used for conveying air, coal gas and chemical gas, it is featured of lower noise, small vibration, high efficiency, smooth running, easy installation and maintenance.
