Is this a place to start a conversation regarding getting the water out of the compressed air?
On my $100 used Craftsman (Devilbiss) 3hp, single stage, dual cylinder compressor I'm working on designing an after-cooler and inline water trap downstream of the tank. I was wondering why the water drops out when the temps are still above the local dew point. I think I found out why - the dew point rises with pressure. e.g. at 150psi the dew point is near 125F. This is why you can build a DIY aftercooler with drain and an inline water separator and it works to get very much of the water out. Do I have a point or am I off track? Or maybe no one cares, which is fine also. This was something I was curious about. BTW - I got the regular oil from HF and "flushed" my compressor, will probably do a final flush with synthetic oil.
