I have a trap at the compressor, then 30' past, a long coil of hose with a drain on the last loop. Cools at those loops. Then I run about 75' of hose to the other side of my house where I have my "booth" tent. At that point, one more trap, then my dry hose that I spray with. On my gun(s), I have a fisheye filter, sometimes. Haven't had water contamination issues for some time now.
