Once you have a goo strong supply of air piped all around your workshop, you tend to take it for granted, and if the compressor goes down, you wonder how you can live without it. Powder particles pick up a negative charge from the corona and ionized air molecules and flow to the earthed substrate where they are held in place by the electrostatic attraction. But, we are talking about fluidization beds right now, and boy howdy does a dirty air supply mess everything up. So as long as the air compressor has a max pressure of more than 100 psi, it will be plenty for most applications. Coat cars, trucks and airplane parts with even cover and easy clean up. You will be able to see the substrate and powder appears in spots. In short it must 'half' the volume of air with each stage. At worst, they will start to build up in the pump, hose, or inside the gun, and grow larger until they either block the hose or come loose in a surge. You may think you have the patience to wait for a 30-gallon compressor to catch up while you are sandblasting a set of wheels. The result is a higher percentage of paint reaching the target surface with condensed . If you have too much powder flowing into the hopper, it will sink to the bottom and cause all sorts of problems.
