NANPU 1/4" 3/8" 1/2" NPT Air Drying System - Double Air Filters, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl 1/4" NPT DFR-02 1

works as it should. only bad thing is you have to drain the pressure to drain the water would be nice if they have a valve or something to open and close.

I actually installed two of these items in my shop. They really work well to eliminate water in the compressor air lines! I would definitely recommend to buyers looking for a quality Air Drying System. Product UPDATE I’m EXTREMELY DISAPPOINTED WITH MY PURCHASE OF TWO OF THESE DEVISES. My initial review was very positive, a huge MISTAKE. After less than 2 months of use, both units LEAK AIR AT THE FILTER BOWLS, the GAUGES BOTH LEAK AIR, the Very FRAGILE BOWL AIR RELEASE VALVES LEAK, and Neither Devise helps to remove water or condensation from my shop pneumatic system. These are just another piece of foreign JUNK. Cheaply made with cheap plastic parts, BUYER BEWARE, these devises are not worth your $ investment, and constant air component air leaks causing my compressor to run on very frequent cycles. JUNK WITH A HIGH PRICE. Don’t waste your hard earned $$ with this company’s JUNK PRODUCTS . Spend a little more, and get a better quality devise. A TOTAL WASTE OF MY MONEY!

Well made, no leaks, compact

Item arrived and iwas hopeful... itvleaked because whoever assembled this cut the o-rings, so it leaked. Luckily I have o-rings so that was a semi fast repair.... it required 4 new o-rings. The nipples supplied were very cheap, cup drains were assembled backwards so it leaked out the bowls. Had to remove the bowls and assemble the valves correctly... all in all it's a shoddy item from China... I should have known it was too good to be true... now I'm wondering when the next weakness will pop up.... I wouldn't recommend this item unless you have real mechanical skills to repair the new item you purchased. Pretty disappointed to be honest.

works well. Leaked air when i installed. i took apart and found a pinched o ring causing it to leak horribly. i flipper i over and is currently holding while i find the proper size.
