I'm thinking of plumbing the garage in a new house for compressed air. I'll have a 220V compressor mounted in a closet in the corner and I'm thinking of running copper air lines within the walls (under sheetrock) except where it has to run along one side which is actually a retaining wall. The lines will run to 2 ceiling- or wall-mounted hose retractors, on each side of the garage. I'd like some suggestions on the air line design please:
1. Is 1/2" copper lines what I want, or do I need larger diameter or smaller?
2. Do I need any drains along the lines for moisture? Thinking I will have a filter/separator on the compressor before it connects to the copper air lines.
3. The compressor will likely be floor mounted (80 gal). Is there need to keep a flexible line between the compressor and the rest of the plumbing? I'm guessing yes, but do I run a short rubber line or what?
4. Is it better not to mount the lines under sheetrock? IOW, do the lines ever need maintenance? Likely I will have a professional plumber install it since it is a new home construction.
5. Are 2 hose retractors enough? In the picture I attached, the red X's mark where they are to be mounted. Should I install more air outlets?
6. There will be a long extension of the lines to a carport off the hallway to the left upper corner (not in the pic) for a beadblaster, etc. Should the line be installed at a slight slope to allow whatever moisture, oil, etc. that got past the filter/separator to run downhill and drain at the other end?
One thing I'm bummed about is that the garage ceiling is only 11 ft tall, and to lift it higher it messes up the rest of the house a bit (e.g. the living room above it will be much higher than the rest of the house). I guess I can live without a 2 post lift
Your comments are welcome,
Dave
