Review on NANPU 0.75-inch NPT Air Drying System - Dual Air Filters & Pressure Regulator Combo with Semi-Automatic Drain and Poly Bowl by Saul Rivera

A few days ago I asked the question"Installed today and there is a big leak in the regulator. What can be done to fix this problem?" Found found out that the problem wasn't with the filter but with how I connected it. He came without instructions, which made matters worse. I connected the supply hose to the end next to the regulator, which was wrong and resulted in a massive air leak at the regulator. I'm writing this in case someone makes the same mistake I did. The supply hose from the compressor must be connected at the end next to the filters. The hose attached to the end of the regulator leads to your tools. If I looked at all the images in the Revain ad, I would see the one that shows the correct setting. The filter works as expected. I hope this helps someone.
