The problem with the setup in their illustration is that they've got
the drain at the opposite end of the pipe from the compressor.  It's
my experience that once the fairly hot and moisture-laden air hits the
metal piping, it cools off very quickly.  That causes much of the
moisture to condense out.  That happens in the first few feet of pipe.
 The way they've got it set up, all of that water drains into the
compressor tank.  I'd much rather have it drain into a few feet of
dead end pipe, with a valve on it.  I do like the way they've got a
drain on every drop.  Make sure you keep them high enough off the
ground to get a bucket under them.

I'd also suggest equipping the compressor with an automatic tank drain.
