[mark 66]

Getting ready to start doing some painting and am looking for a good reg seperator. my compressor is a 2 stage 5 hp with 150 max.all lines are run with galvanized pipe and drain valves at all the drops.dont want to spend a ton but, want to get some decent stuff.had a harbor freight set up with my old compressor but it fell apart when I tried to clean and drain it. anybody got any brand they have had good luck with and would recommend?
