Need help building/understanding a proper filtration system

[Lynx]

I will preface this by saying that my needs are a bit different as I am an airsoft user that transitioned to an HPA platform; the amount of mostly educated knowledge on here convinced me it's the best place to ask (especially a user by the name of "Humdinger")

My plan of action:

1. Buy a Tuxing compressor, specifically the TXET062.

2. Purchase a Tuxing Golden Filter.

3. Properly assemble the filter with the best medium.

I will need the above mentioned set-up to fill 0.8l, 3000 PSI bottles so, with these in mind details, here are my questions:

1. On the compressor's page it says it works without oil, so why should I bother with filtering mediums targeting that as well? Isn't water from compression the singular issue?

2. From my understanding, mediums such as activated charcoal are "gimmicky" in the sense that you don't care about odor or similar aspects, just moisture, meaning you'd only need molecular sieves, as they are more efficient than silica gel beads, especially at high pressures, right?

3. The user I've mentioned says you need a good "water separating tower" before this filter, but what even is that? Just another filter full of cotton, so that the bulk of the moisture is stopped before the second filter?

If you are filling small bottles from a low humidity place, inside with AC, then those small cotton things are plenty. I think you are over thinking this.
You don't say where you live so? Is there another connection from the bottle to the gun? What does it look like? you never did post a picture of the whole top. If you can turn the bottle you are filling upside down, then after 5-10 refills let it sit upside down (30 min) and open the valve to the gun and see if any water comes out, hold some tissue near the valve.

I live in Italy, center of it, really, guess Southern would be accurate; the connection from the tank to the rifle is as follows (photo attached as well): the HPA tank has its own regulator, but it's not enough, so on top of that I applied another regulator, then from that one it connects to the rifle with a line.

Another thing to note is that my rifle (HPA airsoft rifle) does not have any valve that you can open, the line from the tank connects to a line inside the rifle which in turn connects to an engine, which shoots out the BBs out.

I will be filling the tanks inside, correct, but no AC.

Edit: I get a server error when trying to upload a screenshot so here is a link that will show you a set-up very similar to what I have (tank>regulator>regulator>line>engine)

OK then. Your gun doesn't have it's own tank. I do not think you are going to have problems. Just go for it.

With the basic cotton filter (or I could add a secondary small one and just run 2) or the big golden one with desiccant inside?

With such a small fill i expect that 1 small with cotton will be enough as long as you dry before each fill. 2 filrers will be plenty and if you sandwich a few beads of indicator silica you would be able to see how much moisture is getting into the 2nd.

Aight, I ordered it, it only has its filter and that's that, I was getting way too wound up about the different paths I could take so I just went with this one... I'll keep you posted once it arrives and I can have the first fill. At this point, whatever happens is better than mulling over it again and again haha.

If you live where air conditioning is a necessity. Show some love to your HPA pump by operating it in an air conditioned space. Helpful for cooling, but primarily moisture is greatly reduced.

Thankfully it is not the case, mountain region here so it's cold most of the time, even during blazing summers.
