I have a C.H. 5 hp, 26 gallon air compressor that is my only compressor. Question on how moisture is generated to get into the tank? I do have a drain petcock on the bottom of tank. Small tag says to drain it weekly. Ok. I went to spray a wooden chair for my wife earlier this week. Even though, I had drained the tank, there seemed to be some moisture coming thru the sprayer, resulting in a less than desirable finish.
I do have a small filter on the outlet, that has a small schrader valve to empty. It is not a drier type. Do I need to add a drier type of filter to my system to prevent moisture from entering the air hose? How does moisture build so quickly in the tank?
Thanks for any help.
