I have a spray gun that needs 4.4 cfm and 60 psi to work. My compressor is only 2.6 cfm but 135psi with a 6 gallon tank and a 2hp engine. Will this setup work to spray paint?
Sounds like you're using an automotive sprayer. You need to set your compressor's regulator to 60 PSI max or the can may explode. If the compressor doesn't have an adjustable regulator, you'll need to install one.
It should work fine until the tank runs low. Then you go and refill your coffee until the compressor catches up.
