They are craftsman compressors. And this might be a dumb question but i don't know the answer, what's a CFM rating???
If you don't have the specs on your compressors, a rough way to get the CFM rating is to look online for a similar compressor (match up the horsepower or voltage and amp draw to what's on the nameplate of yours).
A HVLP gun actually needs quite a bit of air (as in HIGH VOLUME, which is what CFM is a measure of), so you still need adequate compressor capacity.
A 2 gallon tank oilless compressor probably isn't going to cut it. If it's a 30 gallon tank, 2-3 HP reciprocating compressor, you're probably good to go.
