You want to cool it after it's compressed.  Cooling the air -- by
expanding it to run an air tool, say -- causes the moisture to
condense, and spray out the hose.  An refrigerated dryer works by
cooling the air, causing the water to condense at the cooler, where it
can be drained out.  Chemical driers do it by adsorbing the water,
usually, and can be regenerated by heating them to drive the water
off.

Most systems have enough air in them that the air cools off, and the
water condenses out, usually into the tank, where it can be drained,
or at least isn't expelled out hte hose.
