N/A Moisture in PCP airguns

[coastal drifter]

Most scuba divers have probably noticed having dry mouth after (from the dried filtered air) scuba diving there is even a company that makes a regulator with a metal piece in it kinda like a reed in a wind instrument to catch the moisture from your breath to keep your mouth moist.

New to pcps early last year. Living southwest VA, direct filling with a GX CS4 by itself got water in my gun. Regulator went wonky after a few months and had a table spoon or more of water in air tube when disassembled. Following everything on here I've slowly built to overkill, if there's really such a thing. Condolencing filters, big blue with absorbent then color changing silica beads, then big gold with molecular sieve, with air path feeding against gravity. Fast forward a year, just had to replace valve pin and gun was bone dry.
You'll know far more than me, I've simply followed the advice and can a test that it works.

so by that logic there is no reason compressor need filters to fill scuba tanks

I don't understand the strawman "by that logic". I am simply reporting my experience with compressors and service.


By what logic did I claim that no filters are needed or are not needed? That question appears to be open at this point, appears to be quite subjective, do you agree?

I did not fill SCUBA tanks with any of my (5) Yong Heng/clones, my New Warrior, CS3 or Nouge. I did fill SCBA tanks with my Yong Hengs and clones, for clarity.

"Regulator went wonky after a few months and had a table spoon or more of water in air tube when disassembled.".

That would grab my attention and would likely follow a similar path. I'm not certain that it is germaine but what is the typical temperature and ambient humidity where you are filling? It's simply a question out of interest.

This area is typically 70 F and 50% RH, FWIW.

I'm most likely to be out at my range in the early mornings when the dew is still on the ground and dew points are high. No neighbors anywhere close, so I can be shooting at sunrise. But in the Blue Ridge mountains of Virginia, so there's a haze in the air all summer. Not really one to pay attention to actually numbers.

tampn - GX filter - tampon. Last one is so i can check for moisture.

First fill on 12v pump I had water in the 1.5l tank with only a tampon filter, not sustainable!
