I have been working on my air supply and decided to give this a try:
This is a 100 foot coil of 1/2 pex. You can see the Derale fin cooler core in the center. The air first goes to the cooler core which is angled at about 45 degrees. This eliminates any loop that would collect moisture. When it gets to the bottom, it goes to a Baomain auto-drain filter then back to the top of the pex coil. When that reaches the bottom, it will go to another Baomain auto-drain filter. (All of this is after the air compressor tank, similar to what @TinWhisperer advised).
I have ordered the Harbor Freight air dryer and that is where the air goes next. Thanks to @toolboy recommendation of the temperature sensor switch, which I have ordered, there will be a Lasko 20" inch fan blowing upwards toward this coil and cooler core. Prior to reaching the plasma cutter, I have Tru-Flate Dessicant filter that will catch any remaining moisture.
