I have a dryer at the compressor, then I use an air dryer from a over the road truck about 30 feet from the compressor and then I use another 30 feet of air line from the truck dryer for my working hose. I have NEVER had moisture in my air EVER! I use the working air hose to supply the dryer and pop it off a couple times throughout the day but I never get any moisture from it. It also has a spin on replacement filter that costs about $30. It has worked this long so I am sticking with that.
