I;am no pro. In my shop I ran 2 lines out of the comp. up to the main with a trap on the bottom. the reason for the 2 lines is to slow air down, so the water gos to the trap. this seem to work pretty good. I have sandblasted and run my air tools with no water. If you like I can try and post some pix tomarrow. Oh.if you mount your air comp. to the floor DO NOT TIGHTEN ALL (4) BOLTS. this can cause the tank or motor bracket welds to brake. Leave 1 lose/snuge ,even if you have it mounted on rubber. The vibration needs to go somewhere. Good luck daye
