NANPU 1/4" NPT Compressed Air Filter Regulator Combo Piggyback, 5 Micron Brass Element, Poly Bowl, Semi-Auto Drain, Metal Bracket, 0-150 psi Gauge

Good quality and simple installation. I added it to a portable air tank as a means of regulating output air pressure as well as moisture capture for air brushing. Doesn't hurt to have dryer air for tire inflation also. All works well except the pull up/push down pressure adjustment and lock knob is a bit hard to pull up. That may ease with time.

Very cost effective item. Works great, I like the automatic drain feature.

I like the filtering aspect, and the regulator is spot on and doesn't wander away from set point. I never could stop the gauge/gauge threads from leaking air though. It was leaking somewhere behind the gauge and where it threads into the filter body housing itself. Another gripe is that when you thread the gauge into the filter body housing, there isn't enough room to get a wrench back there to really tighten down the gauge threads that goes into the body housing.I had another pressure gauge in my shop with 1/4" NPT threads. I just purchased a 1/8" MNPT to 1/4" FNPT adapter and threaded my gauge into the adapter. That fixed the leak and I now have a better quality gauge. Luckily, this regulator/filter combo is so cheap, I didn't mind spending a few bucks to get the brass adapter so I could thread my own gauge on it. Unit is now completely air tight.For the price, It's hard to beat the performance of this unit.

The regulator is just as described. Easy to install and works great. I highly recommend this product.

Update, the supplier offered a full refund based on my review. I will use that to purchase the same regulator. Excellent customer service like this deserves a second chance.Did well for 5 months. Now the water drain will not seal and slowly drains my 60 gallon tank to zero when not in use. It needs to be replaced. I haven't tried to get a warranty replacement but suspect that won't happen.

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!

Item functions great.

Just installed. As advertised right out of the box. Doesn’t leak. Regulates pressure.Update. After just a few cycles of pressurization it now leaks constantly thru water discharge valve at bottom. Cannot build any pressure at all. Useless.
