Wanted to run this by you members. I just picked up a Eaton Air Dryer an older unit from a shop that is going out of business. Working last week . The ball drain/ball float assy is all gummed up so I dissasembed it and cleaned it up .I feel maybe the rest of the unit is loaded with gunk and oil so maybe I should just foget about pluming it it in and not compromise my clean air system I have now. What do you guys think. as always Thanks Tom
