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!

This is a good water separator. Some of the parts feel a little cheap, but it has worked good for me.

I am very pleased with this set up. I really like that it comes in several inlet/outlet sizes and volumes. Make sure you choose the correct size and volume for your application. It seems to be a good quality product for the money and I used it to replace a simpler Craftsman one that I had originally installed on my airlines. the tank on my Craftsman failed so I thought I would try this set up instead. It has a nice mounting design, comes with all the necessary fittings and even some Teflon tape. Time will tell, but for now I am thrilled and I will probably add several to my shop airlines where I work.

Just like many people who purchased this product, it worked great for a short period. Now I have a leak between the bowl and housing. It may not be fair but im giving 3 stars. i suspect many issues are caused by over pressurizing the bowl. My compressor is capable of 175psi and i have no regulator before the bowls only after. I suspect many people are over pressurizing these components, but thats just a guess. ill order another filter and install another regulator to protect the filters and see if that works. Really just poor planning and design by me.

I saw the other reviews about how these eventually started leaking, and maybe it was being over pressured, etc. I can confidently saw it's not from being over pressured. I have a regulator before this device, and it's set at 80psi. It started leaking instantly. Not from any of the connections that require the user to put on, but from the middle cup that's on from the factory. I tried tightening, loosening, everything. It just leaks. But, it's not surprising considering it's plastic on plastic threads. I'll just pay the extra money for something that isn't broken out of the box.
