I have an 8 gallon 125 PSI compressor that produces flow rates of 4.5 CFM @ 90 PSI and 5.5 CFM @ 40 PSI. I would like to get a general purpose HVLP spray gun that will work with this compressor.
I would like to achieve as smooth a finish possible without orange peel artifacts. My first project will be spraying clear coat on cabinets, but I will likely use it on other wood projects and smaller metal and plastic projects. I do not plan on painting entire cars.
Other than the CFM rating on the gun, are there any other things that I should look for?
If I select a gun with a higher CFM rating than my compressor, what issues am I likely to run in to?
Best Answer
If your spraygun is too large for your compressor
If you selected a gun that draws more air than your compressor is capable of outputting then you'll be waiting for your compressor to catch up and you will be running your compressor more.
