Depending on your shop you could be required to have a local switch too. There is some tendancy to want to include every great idea a guy has ever heard of, the internet makes it even more acute.
I usedto do **** like that, there are a couple things I learned about it. Not to lose all the little prts, save the instructions and a real hard one is to start simple.
I am acutely aware of this and its also a reason I am somewhat passionate about economy when appropriate. It doesnt mean undersized buried pipebut what it does mean is some salvage on occasion on the other end, some simple manual operation, dont get so caught up in the what iff to only do it once idea.
There are a lot of air options, I have done this wrong, dun it under and over and overkill by large margins is not always the best way. I got no problem with some of the new air pipe, continious is good and might use it for home runs but on the ends I just as soon go to screwed steel pipe fittings, the most common stuff. Get a can of pipe dope and have at it and dont be scared to change,,, figure out where what is and tailor for convenience and proper operation. I like 1/2 in these class garage and shop especially if its not a truck tire service center. A main run of longer pipe is ok especially if its full of turns but I was amazed in my last remodel how many turns I could remove, be patient with design and take it one step at a time.
To start with,,, if you can see the panel within 50 ft simply wire it up and use the breaker. If it doesnt leak it can be turned on/off a thousand times with no load. Only time it needs to start under load is the first if it doesnt have a starter.
Put a ball valve on the comp at the tank, this is the disconnect fpor system air and if some kind of cooling or piping scheme was involved might get creative with a solonoid to service light or even a simple ball valve to isolate a bunch of connected equipment if I had it.
What helps as much is a little detail to leaks, if you are busy with it the cost isnt much but it does cause it to run at some point. If its in good shape and operates correctly occasionally is not a big deal.
My main is live 24/7 and I have a couple stations with old stuff used only occasionally so we put a service valve ahead of it in handy spot and simply turn it on/off, I check once in a while last lap for stuff we use during the day and its not a deal if it gets missed on occasion, it functions but a valve is a little easy insurance. We tried turning other things on and off but they used so regular that we live with a little risk and have a lot of lapping hours someone is thru.
Risk could be mitigated easily in hobby/home simply due to limited connected equipment. My Bud use the same outfit a whole career and had a simple ball valve he shut in and the comp was aired at 175 for 2 years after he died.
My own just came on for the morning, used it once already and some minor leaks cause a cycle or 2 most days. This winter I am going to fix a couple parasitic leaks and things that bug me a bit,,, nothing that really makes a function difference, mostly ocd issues on it, simply bugs me I could have done it a bit different/better.
