How to Dry Compressed Air

There is only two ways I know of to dry air

1....A dehumidifier, which is essentially a refrigeration unit which cools the air and condenses the moisture out and drains it off

2....Chemical dryers IE "dessiccant" which of course the active material must be changed to keep it effective

I don't know why in hell someone would disagree, this is pretty much correct. Anything that cools the air is also under the heading of dehumidification.

Murry posted a photo of an elaborate trap. These help if they are cool enough. In a hot climate and a hot building, maybe not so much. YOU CAN also put a trap in a cooling bath like a garbage can or 55 gal drum, if you have the water to spare
