aloha peeps,
1st post here from a long time lurker of the site, finally made a profile as to communicate with yall,

What are the experts thoughts on oil-less pumps for vacuum set ups?

most I have seen are out of my price range atm, but this link is to one I found that is quite affordable, low cfm tho could be a drawback.

would this be a good option to hook to my vac oven/purging chamber?
experts chime in please

Might be helpful, there is a few other posts Gray Wolf made that are incredibly helpful regarding this subject.

Not chemically rated pump. Internals use EDPM which are compatible with ethanol, but not butane.

this might be out of your price range but a friend of mine SWEARS on Welch products.
