I use a 6 gallon compressor instead of an air brush compressor. I use a good regulator (with a water trap) that allows me to regulate 0-30 psi (I set up two so I can work two airbrushes , although I rarely have). The attached photo is my regulator setup. The compressor is in a separate closet in my garage so I don't have to listen to it when I'm painting. It is plumbed to my painting area through the green hose. This has worked well for me.
