refrigerated air driers?

Sr4440 said
I have a cnc plasma cutter and dry air is everything. The single biggest thing I did was adding an aftercooler between the compressor and the tank (YouTube it) with a passive auto drain. Then after the tank, the compressed air goes through 60ft of copper tubing on the wall before the regulator. The copper tube is a bit of overkill, because i never got water out of the 3rd-6th drains.

Agree. While not quite the same setup as you're talking about, I went with the same concept. I have an Ingersoll-Rand refrigerated dryer that I haven't connected yet, but it will be integrated here, at the yellow circle. Between the aftercooler and filter.
