Bevel cutting design of the impeller in a centrifugal fan can optimize the inlet flow and improve the fan performance. It is analyzed the internal flow of the fore-and-after the centrifugal blower. The performance of the centrifugal blower affected by the bevel cutting design is displayed. The experimental results show that the bevel cutting design can play important role in improving fan performance and has higher application values for energy conservation of the centrifugal blower.
