I use high flow fittings on all of my guns. It depends on the gun but HVLP is about volume not pressure. Also remember to regulate your air at the wall not at the gun. The gun regulator needs to be wide open and pressure drop at the wall. What's the point of a high flow fitting if you choke it to death a half inch away from the gun.
Great, thank you for the info. I have a big radiator mounted to my Quincy along with two water separators, separate pressure regulator and two drains in the copper air lines.
Ive seen where people mount the little filters to the gun, not sure if it’s needed, but don’t think it would hurt.
