Specs
take dirty, oily, damp air from a compressor, and provide very clean, very dry nitrogen to the liquid nitrogen generator
Outline of the process
Air inlet -> mechanical filter -> carbon filter -> air dryer #1 -> air dryer #2 -> carbon filter -> mechanical filter -> humidity sightglass -> nitrogen membrane -> flow valve -> output
