Art,
Not being a mech eng (I play one on TV) I am guessing a lot of what we see is do to the minimal thermal mass in the structure of the compressor. If we add to the thermal mass, then we also add to the weight. The new compressor is coming with a stainless steel, woven hose that is required for operation. I was wondering if a metal tube that had fins on the outside could remove sufficient heat to protect the tubing. We had a rather large shop compressor where I work that had such a pipe. It was a two stage compressor where one piston fed a second piston to get the pressure up. The cooling pipe kept the second piston from heat damage and the flywheel doubled as a fan. The finned tube sat in the draft from the flywheel for forced cooling.
