All compressors draw moisture: At the hospital I manage we have 2. One 30 ft. from compressor another 100 ft. plus at the shop. We have both of the filters higher than our head plus the red line for water full.

I also have the guys drain the compressor once a week. Even home compressors have a drain use it. Moisture is the single number problem w/spray. filter and regulator is a must. Ben
