Easy hookup and operation. I replaced a much older filter and regulator on my 20 year old plus Ingersoll Rand compressor. The PneumaticPlus regulator and filter immediately went to work separating moisture and contaminates from the compressed air. The drain cup is about 2 1/2" long, which seems small. I like the fact it is clear and I can see what is in cup. Easy to read dial and flow pressure is easy to adjust. I used a combination of brass and copper tubes and hardware to mount filter/regulator to compressor as shown in pics to reduce contaminates in air. My earlier setup used steel pieces that corroded from water and age. Lots of dark brown crud inside of the old hardware, so upgraded connecting hardware for this new setup. Haven't ran any air tools yet with it, but see no reason it won't work out OK. May add a second inline filter to clean up air even more!
