Vane or screw compressors?PWE Mag, July 9, 2014
Energy efficiency is high up on everyone’s agenda, not least manufacturers who are increasingly in search of new ways to improve their productivity and save energy. And, with compressed air often considered to be the industrial sector’s fourth utility, a manufacturer’s compressed air system is often a good place to start in terms of making savings. However, not everyone realises that different types of compressors can vary significantly in their performance and therefore efficiency.
Despite the fact that vane and screw compressors were developed at similar times (circa 1950) and are designed to produce the same end result, the two technologies differ quite considerably in terms of energy efficiency, longevity and maintenance.
