Isentropic Efficiency & Specific Performance Metrics in Blowers Explained

Learn more about isentropic efficiency and specific performance metrics as they relate to blowers. In this video, the isentropic efficiency for the multi-stage centrifugal blower is 40% compared to the rotary screw blower at 70%. In this case, the higher the number the better the efficiency. With a 600 cfm unit using $0.10/kW hr, annual operating costs for the centrifugal blower are $30,000 compared to $16,000 for the rotary screw blower -- saving energy & money!
