Keeping the air hose off of the floor helps too, especially if you have a concrete floor. Water will condense in the hose if conditions are right.

This is the single biggest major problem I ever ran in to. Got the hose down to a desireable length and moved the air connectors well away from the actual compressor. I also made a U loop with a pipe about 8 to 10 feet from the compressor in the middle that was about 4 feet long so it ended up looking like a square Y. On the down leg I installed a valve and ran the pipe outside to drain off the water there. Put the dryers in after that and never had a water issue again.
