what water filters are you using on your GX (cs4) compressor ?

I'm getting ready to set up a new cs4. Tentative plan for this is to use one of the Tuauto centrifugal filters with a water drain on the bottom, ($138. on amazon) and then a smaller tampon type before sending air to the guns. Not sure if that is adequate, or how to find out other that trial and error.
This is my first airgun compressor, and I'd like to get it right the first time. Thanks for any input.
 
Congrats on finally receiving your GX4- I did too Friday. I just did a couple of test runs on it this weekend and averaged 34 seconds for the deadhead test. To get back to your question...I am currently using the same filter as you described plus a Tuxing gold with desiccant hooked to my Yong Heng. I added a check valve in between my first stage filter and the 2 "drying" filters. These cylinders take some time to fill up and you don't want to completely drain all the air especially if you're filling larger cylinders in stages. If your just filling guns then you probably don't need a check valve. If you're just doing guns, you probably get away with one external "tampon filter". I will post some pics of my set up when I get home tonight. I plan on hooking these filters up to the GSX4 this weekend...If you do get these filters, definitely check all the pressure fittings-cause mine were not completely fastened and leaked.

Glad to hear that you got your compressor! What desiccant is in your Tuxing gold filter? They've got one with cotton only that's about 13 " long, and at least one with molecular sieve beads, plus at least one other that has charcoal + other content.

I'd like to hear the opinion of others but a centrifugal filter on the output side of a cs4 seems impractical for this type of compressor. The compressed air output of the cs4 is a miniscule 11 liters per minute. This means that the air output is producing very little centrifugal force inside that filter and little or no moisture removal. These types of filters work well in high output 3 or 4 stage compressors before the air enters the high pressure piston. You'll get more benefit from a gold filter with a desiccant cartridge. The cs4 has a moisture trap which removes nearly all of the moisture. A desiccant filter would capture the miniscule amount that gets past the cs4's built in moisture trap.

Can you supply a link to the Tuauto filter? I’ve not heard of that filter.

That's what I'm trying to learn.... thanks for your input. :)

Looks a little messy, but it doesn’t leak…;). I have some fittings coming so I can rid of one of the HP lines…

I use a small one from Amazon. Don't remember the brand. I do know it's blue and comes with a bag of foam discs and cartridges to replace when they get wet. I've used it since I first got my CS4 and to tell you the truth the CS4 factory water separator must be doing a really good job because I have yet to find ANY moisture in the little blue aftermarket filter....none. I leave the little blue filter on just for safeties sake. I read somewhere around here to always have whatever your filling higher than the level of the compressor. Keeps water low in the lines and out of your bottles and guns.

I was under the impression that the molecular sieve beads needed to be able to drain off their captured moisture, and operate in vertical position to allow the water to drop out of the filter into an area with a bleeder. Is that incorrect?

two separate compartments, look up above at Dfp23 rig. One has bleed valve one is sieve
