Another option is to find a company that specializes in air compressor parts and email them about it.
Kerry, I bought a cheap Campbell Hausfeld spray gun when I didn't know any better that was a bleeder type. Big mistake as the bleeder type always has air going through it so it used a lot of air. I have a 220 volt 3hp home built system and it had trouble keeping up. You have to watch when you buy a spray gun as to how many cfm it uses, in fact, you have to watch for all the air tools you buy. Some use too much air for a small portable compressor. Any type nailer is fine, right from 23 gauge pinners up to framing nailers. Small compressors easily run air brushes and touch up guns for painting. A full sized Devilbiss or Binks gun could be iffy.
If you are mainly looking to paint then I would check into an HVLP gun and turbine system. They do the best job with the least amount of overspray. The Fuji system is a bit pricey but I think I've seen the Earlex one recommended here and it's a lot less. The HVLP system uses a very large volume of air at only about 5 psi to paint with. The difference is paint being shot at something or floating it from the gun to your work.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
