Been looking, but the old-school paintball type ASA filters seem to be history. Basically a circle of metal mesh, reported to be a 5 micron filter, that fit between the co2 ank the the marker…work fine on co2 “tankers” as ell, but they damned things don’t seem to be offered for sale any more. Happed to have a few from paintball markers, and they got out to use on tanker co2 rifles (including the Talon SS)
If I find them for sale again, will post a heads up…seems like cheap insurance.
Have to say, have found a few odd pieces of funk” caught in the screeen when changing bottles…could be disintrigrating bottle 0-rings or could be crap in the co2, haven;t got any way of telling.
For the ones tanks set up to fill with a fill nipple (or HPA tanks) Bob Long has filtered fill nipples (they have a little filter in the fill nipple itself) which seems like a good idea. Do not know their pressure rating for HPA or PCP, but they get used on some bulk fill co2 guns.
geez guys…. I’m sorry I used the ‘dirty’ word! 😀
All of the valve leaks I’ve had co2 and air have been from not enough spring pressure on the delrin valve seat or, the valve seat isnt seated properly on the v.stem. The new valve design has a very tight v.seat /v.stem fit. I have had the delrin on and off the stem 2 and 3 times and reseat with no leaks but, the old design is a one shot deal unless you can kick up some metal to grab the delrin again. The CO2 adapters seem to all have the old style valves. I guess A.F. had to use their remaining stock somewhere 🙁
Tag,
I tell you what r60us send me a p/m and get my info to send it too me and I’ll take a look at it, figure out what is going on and fix it some how, that is if a/f won’t stand behind it and replace it for you 😉
Voltar_1 Bigbore dude, this is the definition of helping incase you had
no clue…
I am pretty sure Corey contributed more to this site in one post than
you have in the 900+ posts you have waisted here…
Please, keep your negative comments and brow beating attitude out
of my post in the future. I find it disrespectful of you to interupt what
was meant to be a productive discussion in hopes of finding a
solution…
If you just can’t control the urge to babble,
start your own post and see how many chime in….
Thanking you in advance for your cooperation….
Have a great evening….. 🙄
Glad to hear you will be contributing content we will look forward to it.
So now you claim CO2 was probably dirty in the past….? And that is why one of the best CO2 airguns had a filter?
Bottles corrode and particulates can foul your CO2 valve. Are you claiming bottles can not corrode and leave particulates in the CO2?
To tell you the truth you really are no help and seem to be channeling your buddy SteveNC.
And as a side note if you really are here to help then start by returning those PM’s people send you asking questions about the gun you built.
and who might that be?
no help eh? right…
and here I thought my fights get dirty, I’m starting to think I’m a school boy at it 😆

Wow Walter…..You have been compared to Don G and SteveNC and
yet you still don’t get the hint….
If you’re not going to help or add anything positive to the post, go
build on another gun….People that are trying to get something
fixed don’t need you looking down your nose telling them how wrong they
are….
BTW…You still haven’t supplied any of that great information you say
you have on clean co2…I think you’re full of dirty co2 and hot HPA…..
Next time you want to hijack my post with your pointless drooling, go to the SoftChrono General where you can argue with yourself freely….
Have a delusional life….
You want to see Dirty CO2 then do what I say.

Why does the QB-78 airgun have a screen and filter in the valve?
Why does Tim McMurray get pissed when people remove the screen and filter? He has said many times but maybe you need to ask him.
Give it up big boy and cut an airsource container, when empty, in half and see what you see.
QB78 has one because they are a copy of the Crosman 160
Does the Disco have one? Does the 1077, 2250xt? 850? Gamo?
Any other CO2 guns with a filter?
If I was a betting man the screen and filter date from an era when bulk CO2 was in fact dirty and the seal design could not tolerate any particles.
What exactly does an airsource container have to do with an Airforce CO2 adapter valve leak?
Show me the the dirt I’m still piqued…..

And here link to what a inline CO2 HPA filter looks like that is used in paintball.
Mam, are you not the OP? what has this got to do with the guy with dirty CO2 causing his valve to leak?
Adam, think of teh size of the particles that would be causing a problem in your example… they are ‘bubbling’ CO2. Do you have a guess how small those dirty particles are???? microns. Do you actually believe that that would cause a problem with a valve that opens 1,000s of times more than a bubbler?
guy with the leaking CO2 adapter due to dirty CO2: could you supply pics of your valve seal? and seat?
Mam, take note of Adams tagline before you decide who/what I am.
So I don’t buy the dirty idea.
the leak is most likely due to poor valve plug finish, lack of concentricity or too low a valve spring pressure.
Walter….

CO2 is dirty? first I heard that as we used it in the last plant I worked
at for cleaning high voltage switchgear and the large syncronous
4,000hp motors. 4160 Volts cannot tolerate ‘dirty’ and so we used
CO2 for its cleanliness and no residue.
curious why anyone would think CO2 dirty????
All of the sudden you are an International Quality Control Food
inspector, a welding regulator tolerance engineer, a welder, and a
co2 expert….You must be one of those guys I have heard talk about…
“A know it all”.
I am truly honored to be in your presents…
If you can make the leap that ALL co2 is clean then I don’t know
why assuming there may be some dirty co2 is such a far
leap…
There is one thing for sure, you haven’t helped these guys solve
thier problem..
WHERE IS THAT CLEAN REPUTABLE CO2 SUPPLIER YOU KNOW SO
WELL.
Post some facts and information that we can use Voltar…You say you
will but never do….Sounds a lot like Don G.
Put down the alcohol and step away from the compruter…You are starting to argue with yourself Voltar….
These guys talk a bit on “Diry CO2”

MA957 Clogged Needle Valve Repair Procedure
Over time dirty CO2 gas flowing through the regulator will start to deposit dust and dirt in the small gas line located inside the needle valve. When these deposits become large enough the gas flow becomes restricted and eventually will stop. When you add more gas pressure, forcing the gas pass the inline restriction, the flow will start back but as the backpressure subsides the gas flow and bubble count will also diminish and will again eventually stop. This yo-yo effect causes the operator to apply even more pressure from the large black main regulator knob (Macro adjustment) until the backpressure is so high that the solenoid will not close, even when power to the solenoid is turned off. This high backpressure in the solenoid piston chamber will allow gas to continue to flow through the regulator dropping the pH to 5.5 causing a catastrophic effect on all biological life in a tank.
Field repair procedure – Turn the tank off and take the regulator off the tank. Take the bubble counter off the regulator needle valve. Open the needle valve all the way open by turning the knob counter-clockwise until it stops.
Use a 1/16” drill and go through the top hole of the needle valve and drill through the base of that hole until you feel the drill pass through into the main chamber. Drill time is only about 2 seconds at full drill speed. Turn the regulator over and tap the needle valve on a table to knock out the drill filings. Remount the regulator. Note: If 1/16” drill is not available then go to next size which is a 5/64” drill bit.

During my scuba instructor days, I would routinely fill scuba tanks with our shop compressor. CO2 is compressed as well. Compression of any gas requires several steps and parts to arrive at the end product.
All compressors have filters to get air-borne contaminants out, and use hydraulic fluids in their mechanisms. Our filters were not changed according to the recommended intervals and got dirty, the hydraulic fluids became contaminated, seals became compromised, and oil began to leech into the air pumped into the tanks.
We ended up emptying dozens of tanks, changing the compressor filter, hydraulic fluid, seals, and refilling everything from scratch. Took days to remedy.
This was my experience. I have no dog in this discussion. It just shows that somewhere down the production line from a full CO2 tank, there are a lot of things to go wrong. While it may be very rare, shit still happens.
