I know this has been covered up and down before but I have a question that I can’t find the answer to. I have a Quincy Compressor Air Compressor — 5 HP, 230 Volt Single Phase, Model# 2V41C60VC | 19 CFM
and I want to run about 50’ of copper air lines throughout my shop. 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.
