Anyone running an ATC, what are you using to dry the air coming from your compressor? I have been using a cheap desiccant filter up to now. I am thinking about getting one of the Harbor Freight dryers while they are $100 off. I have heard they aren't bad especially for the price. Anyone else using one? If not what are you using and how much success do you have with it? The spindle is too expensive to let water damage it.
