See lots of worries of water in the guns. Wondering if one could use a small dehydrator/ dehumidifier for the input air side of the compressor. Dryer air in dryer air out. Put the dehydrator in a large box, let it dry the air, let compressor draw from the air unobstructed. This I would think should result in much dryer air though the system. Most of the time we are only talking 20+- CUFT fills 200 to 300 BAR.
