Review on NANPU DFR-02 1/4" NPT Air Drying System - Double Air Filters, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl by Bill Roberts
Generally adequate performance for the price
I have a finned cooler and a large filter ahead of these, but still get water carry-over on some days. I installed branch piping between the filters and regulator. Flow restriction across the filters is acceptable for my purposes. There is a definite flow pressure drop across the regulator. It needs to be adjusted according to the flow demand. The threads on one of the ports were a bit oversized and required extra care to seal.
- Worth the money
- The product may not be as durable as other options on the market
