air compressor plumbing

I would NOT feed the general shop plumbing FROM a regulator. Either put the regulator where you need it, or supply it with quick connects so you can jack it in where you want it for specific tools. Most tools do not need a regulator, impacts, etc, and even air grinders/ sanders which you want to "tone down" a bit can do will with a simple control valve inline near the tool

Really, most important tools needing a regulator is stuff like a paint gun.
