Help me debug / optimize this charging station

I'm attempting to supply clean dry air to my Zelos. Initially, this seemed like a good idea at the time, but after placing this up it appears that I have created a couple of water traps.

From my pump, I have a pressure line to a check valve and bleeder screw.

From that, it runs into a small desiccant chamber. there is a small amount of free space at the bottom of this chamber. I have considered removing the desiccant and leaving this chamber empty as a condensing chamber only.

The next larger gold tube is a desiccant / charcoal filter tube. I thought about removing the charcoal, but wondered if it would assist in removing oil.

Anyway... seems as though I need to figure out a way to rid those hose-traps as I'm guessing water can collect in those low spots.

I could place the pump, bleeder and the smaller filter *below* the countertop, and leave the larger tube above. I could mate two foster fittings directly between the two tubes and lose the middle hose entirely, remove the bleeder / check valve and run the hose below the counter to the pump.

Thoughts?

this is my rig but a double gold filter is coming tomorrow. You’re saying I gotta worry about water possibly in the hoses too?

You are thinking well to not get air in your gun! But, I think just that single larger gold filter should be more than sufficient to filter out moisture. The more volume of space and media you use between your compressor and gun, the harder it is on your compressor to pressurize those along the way to the gun which can cause more heat which then can produce more moisture.....

You got that right, what a wait to pressurize that stuff. I’ll reconsider

Ideally, compressor lowest with upward progression of filters to highest location for tanks/guns to be filled. Big loop in mine but since its after the copper-colored water coalescing bulk water removing filter, not an issue. Didn't start out with water coalescing filter (same one pictured by Blackdog) but everything got soaked so picked one up on eBay for $125, all good now. WM

First, you really don't need to worry about any potential "water trap" after the desiccant filter - if that is doing it's job with desiccant that is not saturated, then there will be no condensation happening at any point in the flow path after the drier. Once the water vapor is removed, it is gone and then simply can't condense unless the temperature falls below the dew point.

If both of those filters are desiccant driers (which is what I understand from what you wrote) then you are clearly over doing it. That might be appropriate for long fills of mutiple tanks, but for filling a gun that is simply overkill, as @Ranchibi siad. Pick one and save or sell the other. If you are only filling guns then the smaller one should be more than adequate; if filling tanks I'd probably just use the bigger one as it will last longer between recharges.

Also, put a dead head or a cap on the fill port at the end when not in use. If you don't water vapor will slowly work up the hose via osmosis and be adsorbed by your desiccant in the filter, shortening its useful life. Just cap it and it will last longer.

If you have a low spot in your hoses which make what is effectively a p-trap, you can't count on gravity to drain those spots completely out. You'll get some clearing of the line when you back-vent through your compressor bleed screw, but it won't empty those hoses over time as well as allowing them to fully drain.
