If you ran 1/2" black steel pipe from one of the air dryers at the compressor to the blast cabinet, and use the
"up-and-then-down" take-off at the cabinet end of the pipe, much of the moisture will condense in the pipe and not make it into the down pipe to the cabinet. You could still put the other moisture trap near the blaster.
This set up works fine for me. I drain a lot of water out of the drain pipe but get no clogging in my cabinet.
