Works as advertised and somewhat better. Really removes oil and water VERY WELL !!! Dr Dave
I shoot an AirForce Texan .457 LSS and a AirForce Condor 25 cal SS. I was not getting what I needed out of my long tube filter with cotton wads, desiccant, and activated charcoal there was moisture getting through. I purchased a 3.0 L tank to fill my air guns. Again moisture was gettin into tank. I finally purchased a GX water separator and was expecting it to keep the moisture out of my airguns and tank. It really worked. Not only did it work but it worked fantastic. The science behind the water removal is sound and it is a great water removal tool for any Airgun or tank. I work for JPL / NASA and the basic rules of keeping water out of places you do not want it are followed. At first I thought it was a little to expensive but after reading the way it removes water and oil from my guns and tanks was simple and sound so I had to try it. Glad I did. The unit is built solid and tough and the attaching magnets work great holding it vertically so it can do its job without having to find a permanent place on work bench to mount it. There is not much back pressure noted. There is a manual drain at bottom of extractor to dump the water it extracts. I already said this unit is solid but again this unit is built very well, good machining, and great materials shows pride of workmanship. It performs very good with no leaks or other issues. It comes with additional activated charcoal and cotton wads. I suggest using a small inline filter ahead of the GX water extractor to get most of water out before it gets to the GX extractor especially if you live a humid area. It works as advertised. Dr Dave, Payson Utah UPDATE: I have been using the GX Water Filter now for several months. It has worked flawlessly removing water from entering my AirForce Condor SS and Texan .457 LSS and Feinwerkbau Olympic Pistol. The filter has not been changed yet as most of the water gets vented periodically by opening water valve vent. Any water moisture gets picked up by the filter. I really like the filter keeping moisture out of my 3.0L and 6.8L air tanks and airgun tanks and internals to prolong life of my airguns. In my opinion, it is one of the best filters out there. Filters are not that costly as you get a lot of mileage on them and very comfortable to know moisture is not getting into my tanks and airguns. Update: Really have used this colescent filter a lot lately, and by far it is the BEST designed pcp filter out there that really works and keeps moisture out of the Airguns. And keeps expensive pcp airguns from being damaged. I do not live in a humid area but we get humid days occasionally and I have several pcp rifles and competition pistols and happy knowing my airguns are getting fresh DRY AIR to their tanks. BEST FILTER available and the cost is very reasonable that will keep your pneumatic pcp airguns from serious corrosion or corrodedparts

Excellent filter
Extremely easy to install and works great. Definitely a step up from the moisture filters I had been using on my compressor for my PCP rifles. Replaceable internal filter units and allows you to drain off whatever moisture collects in the unit as you fill your PCP's. Not much more I can say, just a really nice product for PCP users. Get one, you won't be sorry and your PCP will function better over the long run

Great filter for my PCP.
I'm very pleased with this filter. It's well designed and well made. I like the magnetic mount to mount it on the side of the pump. It gives peace of mind preventing moisture from getting into my pcp.

Just buy this one you won’t find one that works better for anything close to this price.
This is the Gold standard and it’s not price outrageously. If you don’t have one you probably have water in your air chamber that needs to be purged. I did. Don’t waste money on a $70 filter they require more maintenance and media changes, and don’t filter out liquids as well. One thing that surprised me is when you depressurize the fill line it does not completely depressurize the filter, so you can purge the liquid using the purge valve with the remaining pressure. It takes less time to pressurize than my slightly smaller cheap filter that came with my pump. It’s well built The mounting magnets are great

Life of filters. 8 months of use in Hawaii. Should have changed filter sooner.
I have filled my Rattler 357 4 times now and it seems to work well. My concern though is what is the actual life expectancy of the filters? and No information on the GX site regarding recommendations for when to change filters. Plus, no links to order replacement filters. Also on my CS1 the magnets don't prevent it from migrating or moving out of vertical position. Update; after 8 months I should have cked sooner as you can see in the pix. Normally would take 14 minutes to fill my Rattler but last time took 24, so I knew the was a problem.

Best pcp compressor water filter
Outstanding quality. It's built like a tank. Solid and heavy aluminum filter that has magnets to hold it on your pcp compressor. It will keep the water out of your pcp gun.

Ich habe gerade einen zweiten Luftkompressor für meine PCPs bekommen. Er ist wassergekühlt und viel besser und schneller als mein erster luftgekühlter Kompressor. Ich habe nach einem neuen Filter dafür gesucht, um sicherzustellen, dass die Luft trocken und ölfrei ist. Ich habe dieses Modell von GX PUMP bei Amazon mit anderen günstigeren Modellen aus Fernost verglichen. Dieses Modell schneidet in allen Kategorien besser ab und der Preis ist sehr ähnlich zu den anderen chinesischen Modellen von eher fragwürdiger Qualität. Highlights: + Erstaunliche Qualität und wunderschön verarbeitet! + Sehr solide Konstruktion + Tolle Funktionen wie die magnetische Befestigung am Kompressor + Ein Ersatzsatz Filtermedien ist im Lieferumfang enthalten Was mich wirklich von diesem Filtermodell überzeugt hat (es handelt sich eigentlich um einen Koaleszenz-Wasser- und Ölabscheider und einen Filter in einem Gerät), war ein YouTube-Video des Produktdesigners, in dem er die Funktionsweise erklärte (er schickte seinen Entwurf an GX, die das Gerät herstellen). Die Tatsache, dass sich der Wasserabscheider erst bei 2000 psi öffnet, bedeutet, dass Wasserdampf buchstäblich keine Möglichkeit hat, durch den Filter zu gelangen. (Da Wasserdampf bei diesem Druck nicht existieren kann.) Ich habe dieses Modell mit dem günstigeren chinesischen Modell verglichen, das ich an meinem ersten Kompressor habe, und es gibt wirklich keinen Vergleich – dieses Produkt ist in jeder Hinsicht weit überlegen. Ich werde es nun für alle zukünftigen Füllungen verwenden, und es wird auch dazu beitragen, jegliche Feuchtigkeit zu entfernen, die bisher in meine PCPs gelangt sein könnte. Ich kann diesen Filter von GX nur wärmstens empfehlen und würde ihm mehr Sterne geben, wenn ich könnte. 100 % Empfehlung.

I recieved the Air Compressor filter in good time and immediatly set it up on my compressor I was dissapointed to find the water drain release vave was leaking, when I took out the valve I found a piece of aluminium swarf in the valve and noticed more pieces inside the hole i took the filter apart and found a large amount of filings and pieces of fine aluminium inside I cleaned it out but the valve still leaked I believe the O ring and seat has been damaged by the aluminium pieces. This is a very well made and solid piece of equipement, but i would suggest taking apart and cleaning before use.
