My question is should I run ½ lines or ¾? I had a graph showing what size for what length run, cfm, psi, etc but I can’t find it.

Anyway the reason I’m wondering if I should run ½ instead of ¾ is that the outlet on my compressor is only ½, will this restrict me enough to make it pointless to run ¾ for the rest of the system? I plan on running a media blast cabinet, DA, sander, paint gun, etc. I have 50’ of ½ copper laying around right now but I would have no problem buying ¾ if it will make the difference.
Buy the 3/4" - but get iron pipe, not copper. Not only is there a cost difference, but the iron pipe will cool the compressed air and condense out any moisture.
