Easy and cheap way to lessen the amount of water in your system is to put a 3' or 4' U shaped loop in the line with a drain valve at the bottom of the U....
with my seperator, the 1/2" line feeding it, goes into a 90* bend all the way up to the celing, then back down, almost leval with the work bench ( just enough space between it and the work bench, to open drain ), my compressor makes a lot of water, but I never have got water out of the seperator.
