Kobalt Oil-free Compressor spits water
Air is heated when it is compressed, and that hot/warm air carries moisture from the atmosphere. If the water trap is not far enough away from the compressor for the air to cool off prior to reaching it, much of the moisture will pass right past the water trap.
I found a good article about this on the internet years ago. It recommended running at least 50 feet of line slowly ascending up the wall and then down to a down pipe with an upward trending dogleg pipe with a water trap. Then on each end of the 50' of pipe run a vertical pipe with a ball valve on it to drain the water from each end.
I used galvanized 1" pipe for my line that zig-zags up the wall, and not even one drop of moisture has ever come out of my water trap. Lots of moisture will drain from the 2 ball valves though.
