The Ins and Outs of Vacuum Generators | Compressed Air Best ...

The efficiency issue is very clear. While I cannot say that electric driven vacuum pumps are always a more energy efficient choice, I personally have yet to find a vacuum generator application that I couldn't make more efficient by going electric. The pick-up in efficiency when switching from compressed air driven vacuum to ......

Sorting out vacuum-pump technology | Machine Design

Nov 17, 2005 ... A rotary-vane pump's electric motor cannot efficiently cycle on and off to break a vacuum. A vacuum valve can be added for intermittent use, but the motor must still run continuously. In such applications, multistage air-driven pumps tend to be more energy efficient. A pneumatic valve, which simply cycles the ......
