I use a Craftsman PRofessional 6-hp oilless. The compressor fastens directly
to the tank, so I don't see any way to insert a cooling coil between them.
I want to separate it and trap it before it gets to the supply hose.
I've been eyeing Air-conditioning condensers from cars for this purpose.
Why couldn't I just run a short line from the normal compressor outlet at
the tank, adapt it to the SAE fittings of a 2' x 3' approx condenser coil,
then adapt a trap and drain at the outlet, then a coupler for the working
hose? Any reason that wouldn't work? I realize that some condensers would
be restrictive, but I have seen some with fairly good-sized tubes. For that
matter, I could use several in parallel.
