Watch the HP ratings, they are often fictional.

I have an older Black Max 5HP 2-stage on an 80gal tank, which draws 22amps at 220v.
When I built a new shop, I moved the big guy there and bought a new Campbell Hausfeld 60 gal for the garage. It is rated at 6.5HP, but only draws 15amps at 220v. Smells fishy to me, that is actually about a 3 or 4HP motor. The old one will pump the 80gal tank from 0 to 175psi faster than the new one will get the smaller tank to 120psi.

As far as air lines, put a filter/regulator at the tank outlet, and slope the lines down as you go away from the tank. Put ball valves vented thru the wall at the end of each line to blow out any moisture, and run all your outlets off tees running up from the main line. Blow out the lines every few days of use, and the tank drain each day. I've never had a drop of moisture get to a tool or paint gun with this setup.
