For continuous gun operation you need to know the CFM requirements of the gun. If the gun needs 8 CFM @ 40 psi, the compressor need to put out 8 CFM @ 40 psi or more to keep up with the gun. For model work you can cut the compressor CFM a bit as the panels we paint aren't that large. Depending on the compressor, the top pressure cut off will be 130ish to 150ish. You have the high pressure setting down to the gun pressure as a "cushion" in the storage tank will give you a bit of time before you hit the low side of your pressure the gun requires. So even if the compressor falls a bit short of CFM, it's not like you can't use it very effectively to paint with. That is what I do and I get along just fine even when doing some paint work on a car as I mentioned in a previous post.
