California Air Tools 317 Water and Oil Air Filter

Should work great easy to install and use

The Bad:1. The filter was supposed to be BLUE, not GREEN.2. Be sure to fully dismantle the filter so you can clean/inspect every part. The main airway on mine was blocked by a piece of metal, which was thankfully easy to remove with a long wooden q-tip (see pics).3. Be sure to lightly oil the o-rings before reassembly or it will leak air. They don't come oiled.4. The threads on the green part are horribly cut, such that several pieces of metal broke off when I first installed a brass fitting. This wasn't excess metal, but rather, actual chunks of thread that broke off.5. The filter can't be installed before the regulator because it's only rated for 90 psi.The Good:1. The clear polycarbonate piece is MUCH thicker and MUCH nicer than I expected. It's easily the nicest part of the entire filter.2. The filter has a solid metal core, from end to end, so the polycarbonate is not a stressed/structural member. In other words, you don't have to worry about the polycarbonate cracking.Overall, this isn't the type of filter I needed. It's meant to mount directly to a handheld tool, which will keep it vertical and at a low pressure (because the pressure drops 30 psi over the length of a 50' 1/4" air hose). It's too bad the listing didn't explain any of this. It also would've been nice if the box contained SOME sort of instructions. It took several hours of online research before I figured out the correct polarity (the BLUE/GREEN end is the OUTPUT!). The way the filter works is that dirty air enters the male fitting, fills the inside volume of the polycarbonate housing, filters inward through the bronze filter element, and then exits cleanly through the blue/green (female) end. There is much arguing online about the correct polarity, but if you do a Google image search for "kobalt inline moisture filter," you'll see that OTHER brands were smart enough to include a polarity indicating sticker on the outside of the housing.This isn't a filter I can use for a compressor-mounted install, but it's still a decent item for the price. I deducted 1 star from the rating because it's the wrong color, and another star because the female threads are shoddy (which caused metal slivers and green chips to enter the air stream).

I actually went into this not understanding it was meant to be run at the tool end due to it's relatively low PSI maximum rating.With this in mind, I just gave it it's own quick disconnect, as some things need it more than others.Same as someone else mentioned. It's a green version, not the blue pictured, and machining is a little rough around the edges. On the painted end, My coupler actually bottomed out before tightening fully. Can't say that's ever happened before.It doesn't leak, so it's fine.. Just odd and worth a mention.Cheap and likely works fine. Perhaps it's stronger than it appears. I'll leave it in place and see :)*EDIT*I got to searching around for other options.There's considerably higher quality ones from Neiko. Less for their 90PSI version, and about the same cost as the CA air tools version for their much nicer made all metal higher rate filter.If you do an Amazon search for 'Jewboer Water Oil Separator' you'll see, again at about half price, the identical same air separator, again for about half the cost as this one.

This does what it says it will do. I thought this inline model would be a good choice but I'm not sure it is. When you put it on the tool side it adds extra length to the tool's attachment and it tends to bump into things leaving me fearing it will break off. On the compressor side it sticks out from the side of the compressor and I'm afraid someone, or I, will walk by and bash into it breaking it off. Maybe my fears are unfounded, I don't know. Only time will tell.

If the air is dry to start with this Water separator works very well on the water caused by the compression of the air held in the compressor air tank. However on a rainy day or humid conditions it struggles a bit. I Airbrush on T-Shirts and any water spitting can ruin a shirt.The clear casing is great, as it lets me know when to take a break, it fogs up when it is being over worked.Using it with quick disconnects is helpful as well, I remove it after each project and let it dry out.

The one got seems fine, we haven't had any water get to it to test, but so far so good. A little bit on the small side and the pressure release valve (which looks like an inner tube valve) is easy to hit when wrenching the thing into place so watch out for that.

exactly what I was looking for.. Now, I feel that the air is clean and dry.

Seems to help with moisture.
