I agree with both atomarc and J Lucas on everything they have told you. We also pull air off of the top of our air line by using T's. Anything you can do will help. The more the compressor actually runs. the warmer the air, the more condensation and moisture being formed. Some jobs like running a DA, die grinders etc. take a lot of air if you are running them continuously. The only real solution is a bigger compressor (less run time) or some kind of air dryer, either desicant or refrigerated. Desicant is cheaper than refrigerated, but refrigerated is almost always the best for totally dry air. Check first and see how often your compressor is running, if very often, than refrigerated is probably your best bet. (but expensive)
