Review: Good regulator, works fine. Pro tip at end of review - This is a solid little regulator\filter. Works just fine. It comes with two 1\4npt nipples and a 1\4npt, male and female quick disconnect. The nipples are made from aluminum and the quick disconnect is plastic. I was actually surprised I got these, guess I didn't read the info. I know, aluminum and plastic? I'm sure if you used them they would work just fine. The only complaint I have is that the adjustment knob is kinda slick and smooth and tapered a bit making it hard to adjust because you need to pull the knob up to unlock before turning. This has a "semi automatic" drain on the filter bowl. This means that when there is no pressure going to the regulator the little valve is open and will drain liquid. When you turn on your compressor the regulator will sound like it's leaking air for a few seconds until it reaches about 5 psi and the bowl valve will seal and you're good to go. If your system is always pressurized you will have to disconnect the air to the regulator to drain any accumulated water in the bowl. Pro tip: Do not connect this directly on the compressor. Connect 25 to 50 feet of air hose to the tank. At the end of that hose connect the regulator\filter. Doing this allows the hot air coming from the compressor to condense the water vapor into liquid water so the filter can catch it. This is important when you are doing spraying or blowing and the compressor is running a lot. Also, the specs may say that this unit can be used up to 175 psi, but if you don't need 175 psi adjust the output to 125, of you can.
Review: Great Product, works as advertised! - I couldn’t be happier with the NANPU 1/4" NPT Compressed Air Filter Regulator Combo Piggyback. From the moment I set it up, it impressed me with its ease of use and quality construction. The brass element and poly bowl feel solid and well-made, giving me confidence that it will hold up over time. The 0–150 psi gauge is clear and accurate, making pressure adjustments simple and precise. The semi-auto drain is a great feature that takes away the hassle of constant maintenance, and the included metal bracket and ball valve make installation straightforward and secure. What I like most is that it does exactly what it’s advertised to do—regulates air pressure consistently, filters moisture and debris effectively, and keeps my tools running smoothly. It’s rare to find a product that combines functionality, durability, and ease of use so well. Highly recommend this to anyone looking for a reliable air filter regulator combo that performs flawlessly!

### ⭐⭐⭐⭐ Does what it should do
*by T***R on January 18, 2025*

I'm pleased with this little regulator. I'm using it only for a small oilless airbrush compressor, and it works fine for my purposes. I like the automatic water separator bleed, although my compressor doesn't move air fast enough to set it automatically (I have to manually hold it shut for a moment at every startup). This way I never have to remember to dump it before running into problems with my airbrushes. This was worlds away better than the original regulator that came on my compressor.
