Review on NANPU DFR-02 1/4" NPT Air Drying System - Double Air Filters, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl by Geoff Foster
Nice unit but gauge does not thread properly into regulator.
I purchased two of these units to replace two older regulators and add additional filtration. The units work fine BUT the gauge threads are not long enough or the regulator sides need corrected to allow the gauge to securely thread into the port tight. I had to add a close nipple which required a coupler to properly tighten into the gauge port. Issue is- The gauge now sticks out quite a bit. I feel this area was not properly designed / checked for fit. If this is not an issue for you as the buyer, then the unit works fine.
- Easy to setup
- The product may require frequent maintenance or replacement of parts
