Review on Hromee Air Compressor Filter Regulator Combo Kit - 1/2 Inch With Pressure Gauge, Semi-Auto Drain, Water & Oil Trap Separator, And Bracket For Improved Performance And Efficiency by Dave Wolf

This device will work for us, but only as a filter. The regulator function is unacceptable and unusable. When the setting on the regulator is anything below the input pressure it appears that it does regulate the output pressure perhaps correctly, but it also vents air continuously as long as the input pressure is higher than the output. My small compressor has to run a lot to keep the pressure up with the constant leakage. The instruction leaflet is of zero help. It was translated from some other language by someone who seriously lacks in their knowledge of English. Some of the statements are truly of no use, as I had no clue what they were trying to say. You get what you pay for. It's a lot of "device" for $17 so I'll keep it. I think it will help clean the air from my compressor for winterizing our RV. I hope!
