Air line Q- No doubt a repeat, but please?

[HHStang]

I'm planning to run 3/4" copper in my new garage to give me multiple air connections in the garage.

Can/should I run it through the concrete or in the walls? I'll run mostly air tools like sanders, die grinders and things like that if it matters. Does putting it in the concrete give me more moisture as I have 1/2 lines in my current garage and seemed to get alot of water in the lines.

Thanks!

When you say run it through the concrete, are you talking about running it in the floor? If so, I wouldn't suggest it. You won't have any way to drain the water out of the lines if they're in the floor. I would suggest running them on the wall, not in the wall, but thats just me.

If you have a refrigerated drier, then by all means go ahead and run it through the floor. If not, I too would advise against it. At work, all the air lines are run through the concrete slab. This means there are just lines running up the walls for air hose "drops". We dont have moisture because we use rotary screw compressors and a refrigerated drier. I have worked in another shop with a piston compressor and regular filters. These lines are run in the slab and there is a TON of water in those lines. The compressor is pulling in hot air as it is because of its location, so that only makes the problem worse.

copper + concrete = corrosion

The way I installed my air lines in the walls, fwiw.

I wish I had thought to stub in 2 or 3 drops from the ceiling. I still can do it but it is going to be more work to do it now - would have been eaiser during the build. I have 20 outlets for air now, 2 are outside at opposite ends of the shop. 15' of hose will reach from an outlet to any spot in the shop but the ceiling drops would allow me to hook up to a couple of machines without any air hose on the floor.
