When do you use oil-free or oil-lubricated vacuum pumps?


Oil-lubricated vacuum pumps achieve a very high level of the final vacuum of 99.9% (= -29.5 inHg), generate high volume flow and can sometimes be used even in moist or humid ambient conditions. Moreover, they are suitable for continuous operation.

Oil-free or non-lubricated vacuum pumps generate high volume flow and a high level of vacuum (up to -26.0 inHg). They are particularly suitable for dry air, when the vacuum level changes frequently, and also for constant low-vibration extraction.
