  • Great quality
Size: 3/8" NPT Style: 5 μ
Duel filtering with automatic water drainage. Used it pretty hard with a DA sander and did a great job. Great product for the money.

  • Nice Design, quality parts, Perfect Addition To Shop
Size: 1/4" NPT Style: 5 μ
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! ... show more

  • Works great for my needs.
Size: 1/4" NPT Style: 0.01 μ
I’m using this for small spray jobs on rehab furniture. I’ve only shot water base paint so far, but it does separate the moisture from air. I get no detectable moisture from spray gun.

  • Heavy water removal, NOT a drier
Size: 1/4" NPT Style: 5 μ
The media could not be loaded. Pressure regulator works. I dont recommend using the supplied sealing tape. It does collect a good bit of moisture. Once you deplete the system it auto purges and thats nice. It is not a drier by any standards, moisture will still get to your tools. I put an inline desiccant cartridge after the regulator and all works great. A good cheap alternative for home use air systems. ... show more

  • drain valveon .5 psi leaks for the first 20 psi
Size: 3/8" NPT Style: 0.01 μ
what i notice is that bleeder valve .1 filter holds at any psi. but the .5 filter doesnt and leaks till psi above 20psi. i try to work valve in seat with no luck. so in operation .5 psi filter would leak till system pressure would be above 20 psi and then things would be ready to go. The leak is NOT BIG so it doenst really slow down the operation. i have not look into actual removing valve from bowl yet, figure jsut return it if it gets worse. good luck. ... show more

  • Horrible design
Size: 1/4" NPT Style: 5 μ, Metal Coupler & Plug
The design is really bad. There's a little button at the bottom of these that you press to eliminate water from the system. They have a little spring and o-ring seal on them so that they stay air tight when the air is running through. The air pressure going in is supposed to seal it. Within 2 days of installation that area started leaking. The filters seem to catch debris which is good, except for the fact that the debris makes the o-rings not seat properly which lead to air leaks. I decided I just wouldn't push the button unless the catch was full of water so I cleaned and greased the catch cup and o-ring thinking it would stop the issue. Again, it worked fine for a day. The next day it was leaking again. This company needs to re-design the water drain function because it makes the whole setup useless. If you do buy, I would recommend NEVER pressing that button and allowing debris to get under the o-ring. ... show more
