Eric,
I had an oiless Craftsman 60 gallon NON Movable , for a long time and painted with it settin there . NO PROBS..only thing I recommend is that you change the filter after every session as it will suck in the overspray ...and the next day your filter will be clogged and hard as a rock !
I quit buyin the craftsman filters and replaced it with home made ones , I would buy a pack of Scotch Brite pads (for scrubbin dishes) and cut them up for filters that were cheap and disposable.
Just a tip
