If you are talking about sandblasting then a oil less air pump is offered. We sell blasters and parts. And we have an oil less air pump which is driven by an air motor which gets its air from compressor. It is new and never got sold. But
about 100% blasters get breathing air off compressor air after it goes through NIOSH approved breathing filter and breathing line to hood. I have not seen any issues whatsoever in 50 years of being around blasters.
Recommendation is to change charcoal breathing filter when changes air has odor,etc. so it is easy to when to change.
