I'm back out in the garage tonight back on this. Looking at the wall behind my air compressor and doing something like the drawing looks very possible and not a big deal to do. Raises a couple new questions
I assume black pipe will work well for this?
3-4' high be sufficient?
Then should I go from the pipe to my 3/4" filter/regulator then to my "t" to my loop? I believe the filter has a drain fwiw.
Filters then be necessary for my sandblast cabinet and paint drop?
