Today's front page photo (Paul in Oz) reminds me...I ran across this illustration in the bottom of a drawer. It's from Sharpe, the spray gun people, the correct way to install your shop air supply.
The fundamental principle is simple. A long run of iron pipe cools the hot compressed air, condensing the moisture, which drops into on of the multiple drops spaced along the run.
My shop has 60~70 feet of 3/4 pipe prior to the drop I use for painting. Actually it tends to be a general use drop, as the long shop flex hose stays connected there. It all stays dead dry. I have a bead blast cabinet at about 50 feet, and it stays dry too.
