I have been thinking about getting the fitting to blow the water lines out but have put it off because I have noticed that I get an oily water from the air hose. It is nothing that you would normally see but I have felt it when operating the impact wrench and air saw that exhaust on my hand. I thought it was just the tool so I put a blower on the hose and blew into a paper towel and got an oily damp spot on the towel. Do most people just use the air direct from the compressor tank or do you run it through a paint sprayer dryer.
