GX CS4?

OK - So back to my last question.

Did you mean to ask what filter should you use between your compressor and your SCBA tank? If so, the large gold filters with built in replaceable/repackable cartridges are a reasonably priced effective option. If I read your question literally, I've never heard of installing a filter between a fill tank and an air rifle.

I guess I mean both. If I already have water introduced to my 45 min. tank from filling without a filter I need a filter between gun when I use it to fill my gun.

I assume one of these is what your referring to.

I you suspect you have water inside your tank, I would empty the tank, removing the valve, inspect the tank, drain any water, reassemble. Then ideally refill using a either a suitable filter between the compressor and tank. Water left inside that tank over time will damage the aluminum liner.

That or the blue one. But you don't need all that charcoal, I'd dump 2/3-3/4 of it and replace it with more 3A molecular sieve.

Now when talking dissectants, you will some dwell time, as it is not and instant type of absorption.

@BlackICE , @F6Hawk was just having some fun - I know he agrees with what I wrote.

I agree with your points - I have read comments like all seven of the ones you listed and I just shake my head . . .

Sadly, it is just like so much of what is going on in our society right now - people want to believe what they want to believe, and actual facts have no place in their life. Facts matter. And in our hobby, if somebody compresses air with a powered compressor, water will be condensing out into liquid in the destination reservoir if the air charge is not actively "dried" with an appropriate desiccant filter (or a chiller that cools the air charge below ambient use and then passes it through a coalescing filter - but a desiccant is easier and probably cheaper too). That's a fact, derived from the actual physics of the situation (I know that you both know this . . . written for others that read this).

Is that the right order to connect the filters? Compressor-->desiccant filter-->coalescing filter-->dive bottle/gun cylinder.

I thought to put the coalescing filter first, to get more/ longer use out of the desiccant.

I was not talking about the order of using filters, but of the choice of only two paths that would be certain to prevent condensation from occurring in reservoirs: either 1) a desiccant filter to adsorb the water vapor, or 2) a chiller to cool the air charge below ambient with a coalescing filter as part of the set up.

That said, using a coalescing filter before a desiccant it a very good idea, because it should help it last longer - of course the trade off is more "wasted" compressed air that evenetually gets vented rather than used. An even better idea would be to put that coalescing filter in a bucket of ice water to further cool and condense even more water vapor into liquid before the desiccant does its thing . . .
