Are there misperceptions out there on compressed air-driven vacuum pumps?
There is a misperception that all compressed air-driven vacuum pumps are inefficient. This idea exists because of the historic use of single-stage venturis which have a relatively inefficient 1-to-1 ratio (1 scfm of compressed air creating 1 scfm of vacuum flow). This has reflected poorly upon the entire category of compressed air-driven pumps. Also, technology has evolved, enabling us to reduce the size requirement of the vacuum system. This new technology, when applied accurately improves speed and reduces energy consumption. All pumps are not created equal. There are dramatic differences. The key to understanding them is a well-rounded education on vacuum systems. PIAB vacuum pumps are of the multi-stage ejector type- a technology patented by PIAB in 1973. Large vacuum flows and high levels of vacuum are characteristic of these vacuum pumps. These pumps offer 3 to 6 times the speed and efficiency of single stage venturis. This is made possible by our COAXÆ technology.
