NANPU DFR-04 1/2" NPT Air Drying System - Double Air Filters, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl Review

Purchased this five months ago but finally got around to installing it today. It’s been under full pressure for about 20 minutes and it seems to be holding up just fine. My only concern is if it will last through the cold winter months as it gets down to about 20° in my garage. The description states the the temperature range goes down to 41°. So I guess I’ll just have to see.

I was surprised while trying to reverse mount the NANPU ! After you remove the mounting bracket screws the unit came apart in several pieces. I was expecting the mounting bracket to come off not the entire unit to be rebuilt .it wasn't hard just unexpected.

Better quality and for a cheaper price than the one I purchased from lowes. Thanks for attention! Holding 150psi for a few days now

Everything worked great from the installation to the function, its just the gauge itself has a small leak, I sprayed windex on it and sure enough bubbles from the inside of the gauge, If this company could send me a new gauge things would be great.

I purchased this to set up my compressor for basic air tools. Seems to work good and compared to the price that any big box store it's a steal. 0 complaints after 1 month.

The system works well. I had a problem with the regulator gauge leaking air from the gauge and not the connection. Instead of returning it and going through taking it all apart, I went ahead and upgraded the gauge from another manufacture. Now all is good and working properly.

Bought for my plasma CNC . I haven't had a chance to install it yet but I have another one on my compressor and it works great

Make sure you use plenty of Teflon tape, fittings leak, and parts of the body leaks so I had to do some fixing. May not fit into some compressed air systems due to size constraints.

Had to get a couple of extra fitting to make fit on my compressor. Doesn’t really separate the water from the system as good if using for a while

Works well. Time will tell durability. But I use this thing in a wide function. From air tools to spray guns, all the way down to boost leaks in a truck.

It works fine. I received the item in excellent shape except for the gauge. The glass has a huge crack in it. It still functions correctly so not a big deal. This is really heavy duty.

This was an inexpensive option for my air-drying needs. I got what I paid for.It works but has a slow air leak. I have tried many things to get rid of the leak but it still leaks.Very slow leak my 60 gallon compressor kicks on once every 6 - 8 hours.

I had leaks between both filters and air coming out of the back of the regulator. I ended up putting pipe nipples between the filters to solve the leaks. the regulator itself still leaks out of the screw hole in the back.It works fine, just leaks a lot.

doesnt leak comes with instructions didnt really need them or use thread tape not sure why others didnt like it im satisfied

Bought this to add to my water separation system on my air compressor, this didn't catch any water while it was on my system I had 2 more separators set up past this unit, the separator next to this caught a lot of water that went right through this pos and I have one final separator at the end of my air hose that attaches to my hvlp sprayer that caught any remaining water that the first 3 didn't. After 2 weeks of use the diaphragm popped and now has a hole in it that constantly blows air, the…

My pressure gauge glass came cracked! Please send new gauge! The rest of the product is perfect!Thank you May require additional training for novice users to properly maintain & operate!
