Re: air compressor question
The compressor should state what cfm (cubic feet per minute) of air it can supply at a certain pressure, the paint gun should have the requirements with it also. One thing that helps me run a framing nail gun on a small 1hp compressor is adding more hose, the hose adds expansion capacity and the motor runs a lot less. 150 feet of hose is what I use.
