Dry vacuum pumps, as the name suggests, are pumps that do not use oil in the chamber in order to create a vacuum or to cool the pump. Oil-free vacuum pumps are energy efficient and eliminate the need for oil replacement and disposal. Dry vacuum pumps come in varying technologies including diaphragm, screw, and scroll pump technologies.
Oil-free vacuum pumps are particularly useful in food packaging and processing, pharmaceuticals, and medical facilities where leaking oil and machine down-time could have large consequences.
