Another thing to think about for shop air lines is the size of the quick connects. A lot of quick connects have a 1/4" not thread. If you look at the size of hole in the fishing they are necked down considerably. When spraying paint there can be a considerable drop in actual pressure at the gun simply because the fittings in the system dont allow flow. Without the ability to flow the pressure at the gun fluctuates. We set the pressure with a reg at the gun while flowing air but when we release the trigger the air pressure will spike. When we hit the trigger again the pressure is more so the gun pattern will be different until the flow available drops and the pressure comes back down to what we want. The same goes for other tools. If you have air hose reels check the inlet fitting sizes as they are another source of restriction. A 3/8 not fitting there would be good since a lot of the swivel adapter fittings to supply air to the real have small internal passages as well.
