I've kind of been working on this off and on and finally got pretty much done today. I've been wanting to invest in some new Snap On air tools, and I figured that if I spend the kind of money, I want nice, clean air to run them. So anyway, I started by hanging a diamond plate aluminum sheet on the wall to hang the filters and a couple water traps. The big long cylinder is full of desiccant. I ran the air line into the attic where I have one drop between the garage doors in pretty much the center of the garage ceiling with a hose reel. I've got another line ready for another hose real at the other end of the garage and I've got a drop set up where I can plug a hose in right by the garage doors where I can run a line out into the drive way. All of them have water traps. Now I have nice dry air for all of my air tools.
