Depending on your set up, you may want to build a cooler/dryer for your compressor. I know copper is expensive, but running a half dozen or a dozen 8 foot lengths of copper tubing up and down the walls with elbows to connect them and putting the output of the compressor in to it and your supply line out of it (with a couple drain points) will do wonders to cool the air and cause the water to precipitate out of it. A lot cheaper than a commercial chiller, and much better air quality exiting the system.
