I'm not really getting why his present setup won't work? It has the dessicant beads etc. But maybe I didn't read your post carefully enough to understand the difference. Is the type of beads used the problem needing to be replaced by the kind you gave the link for?
Sorry for my ignorance on understanding what the problem is other than the price.

wesb2007, did you mean me?
My understanding is the OP's filter has no filter inside, just like the bogus ones I've tried (and have at work) plus he said the mfg claims "no maintenance...no consumables" which tells me it's just an empty container. I'm also wondering how much this filters volume adds to the guns fill time... Looks pretty big, so with a typical gun I'd guess double the fill time?
The pix Avianmanor posted is an actual filter. Not sure what it goes in but it no doubt works great (I assume the white beads are for water) plus the cotton and charcoal. Not sure why the charcoal but why not ;) As long as the water and debris are filtered out I'm happy, that is as long as it can be dried and reused... I have a friend that buys non-reusable water filters for painting cars, so ~$30 per paint job down the drain. He considers it an operating expense, I consider it what it is; $30 off his net profit... I offered to make him one of mine if he bought the parts, but ironically he won't spend the $!

ddv2005: That cooler dealie is interesting but I don't buy it at all. I'll assume it's the mfg/sellers claim, and seeing you have only one post I'll assume you're the seller. The pix looks like it was photoshopped by a 4yr old, and no way that "filter" will be cooler than ambient during actual use. Is that 3.5 in the pix actually suggesting the tank is 3.5 degrees C? Really??

My bad Chevota and my apology. I thought Avianmanor's three stage alpha filter was describing the OPs filter. Shows how well I pay attention.
I thought your comments were about the filter Avianmanor showed.

Anyway, after all my foolishness I find myself agreeing with you now that I have clued in!

How hard was to make it?

Twinflower: If you meant me, it's super easy. The in/out ports are 1/4NPT so I plugged the inlet and put an air fitting on the outlet. The out port will now be the in port. In the bottom of the housing I drilled/tapped for 1/4NPT and put an air fitting for the outlet. Now air enters the center inside the lid, passes thru all the desiccant and exits the bottom. I do it that way b/c the first packs catch most all the moisture so optionally I can just swap out the wet ones on top. When I'd sandblast I used a LOT of air so I sometimes did that, but with an airgun or tank I can't imagine the need.
>>>>> This is NOT for the high pressure side!! <<<<< This container is only rated for 125psi and despite my belief that it'll easily handle that, I still don't feel comfortable having it next to me considering the power it would unleash if it did blow so I put it behind my pump just in case. So to be clear; if you put this on the high pressure side of your pump it WILL explode and no doubt be a big one! It would easily have the power to take out an eye(s), teeth, maybe even kill you! Likely the threads holding the body on will fail which means both pieces will launch violently! Either way = bad. I hate to sound like a products safety label (which I hate) but this is outside the box stuff so you gotta be wary. Since the 125psi fittings are larger than the high pressure ones there's little risk of plumbing mistakes, but I'd hate for someone to find a way...
Also note that since the container was modded with the 1/4NPT hole in the bottom, it would void any oem pressure rating. This one, as most do, has a very strong/reinforced area where I drilled/tapped and I believe it did not compromise the strength at all. Someone else doing it, or using a different make/model container it may not be as strong.
If you have a diff comp and can only access inlet air then I'd make an inlet filter. I'd make it from a soda bottle, tube, cardboard box etc filled w/ the desiccant packs so it draws air thru them. That will be less effective but it may work well enough. I dunno, never tried it but desiccant is cheap so worth a try imo.

wesb2007: zero apology req'd. I skimmed thru this post at first and also thought that cartrige was for the op's container until I saw it couldn't fit.

desiccant has to be packed tightly... you can't have bags with voids between them...air will just channel through...

I agree it would seem like that's the case but it works. Remember I was deperate when I made this some 15+yrs ago, and this was the first attempt using dessicant and it was all I needed. This is my third one...
When I used this for my sand blaster the bags were even looser b/c they were larger and harder to pack well, yet the air was nice the dry. Plus consider the speed and volume of air i was pumping thru vs the little bit a pcp pump does, so you'd assume even less chance to catch the moisture. As mentioned the bags on top would get soaked before the bottom ones were affected so it was clearly very effective.
