Review on NANPU Three Stage Air Drying System With Premium Filters & Gauge For Precise Air Control - Semi-Auto Drain And Metal Bracket Included by Stoner Fulton

The auto-drain mechanism at the bottom of the bowl are terrible. I waste more time letting the air out of the system to unscrew the bowls and fix the rubber gasket. They will slide up the little metal tube that lets out the water and leak air until you reset the gasket. I was going to return the but missed the return window by a few days. Buy something better if your time is valuable to you. You’ll be tinkering with it endlessly. Or just let it leak air and use your compressor needlessly. It does separate water well enough. Water does still get through to the last filter when it’s humid. I’m in Colorado so our humidity is nothing compared to most other places.
