home garage compressor: how many CFMs?

We've run some critical 3" water lines here by running the lines through a
6" SCH80 PVC pipe "casing".  Joints in the 6" were accomplished by splitting
the couplings or tees and clamping them together over the pipe ends.

With air lines, you'd probably want set up a casing to run slightly downhill
in the direction of the air flow to help the moisture to run toward a water
trap.   Using metal lines and if your run is 100' or less, you could
consider running something similar to *FrosTex Plus to keep the lines at a
constant temperature (haven't done this with air lines, but it might work).
Alternately, a little over-pressure in the room at one end of the casing
would force room air into the pipe.

An added plus (and the reason that we originally did this) is that someone
shovel digging in the vicinity of the line will hit the SCH80 6" first.

*Self-regulating, non-thermostat controlled, heating cable (must use
"FrosTex Plus", not "FrosTex" or "FrosTex II"):
