I have a Ingersoll Rand model P1IU-A9 air compressor that's rated 4.3 cfm @90 psi and 3.2 cfm @ 135 psi. It's a 4 gallon unit and rated at 100% continuous duty.
I'd like to buy the Harbor Freight 20 oz. gravity feed hvlp spray gun. (the purple gun) Harbor Freight says the gun needs 6cfm @ 40 psi.
Will my compressor handle spraying water based poly with this gun?
