According to Cooper-T, they run out of stock of 3.5 oz while back ago - right across US, and then I found out from Tim at Mac1. They're discontinued and now they have 4 oz.

Airsource = 88gr. = 3.14 oz

Yeah...there are still a few floating around on eBay but I don't think they will ship to Canada. But then again, Airsource is lighter which suits me well.

Are they labelled as 'Refillable'?
What overpressure protection do they have? Where is the burst disk?
Chilled and then filled? Potential for overfilling and you have made a bomb. Still think you should refrain from advising others to do this!
Sounds dangerous and hope no-one finds out how much shrapnel one of those containers becomes.
Bad deal in my sometimes not so humble opinion.
Be safe.

It's definately DIY, don't think you'll find a store that will do a refill for the reasons you stated...however, they are refillable in theory....AT YOUR OWN RISK.

That is exactly what scares the heck out of me.
This forum has a wide range of understanding and ability. I think it wrong to advise the general airgun enthusiasts of a practice that is decidedly dangerous and subject to huge fines. There is a reason why these things are throw-away. the reason they get away with the light construction is the life cycle = once period.
Throw them away. Get a paintball tank and play safe for a long time!

I'd be more than happy to....please find me a 3.5oz paintball tank and I'll swear I'll never touch another Airsource for as long as I may live....so help me god.

Hey no trouble,
Get out the cash and order them up from Tim Mac1.
The last one I got was from him with shutoff valve.
Good deal too IIRC.

How much did the 4oz bottle cost you in $CDN with shipping, taxes, brokerage fees etc etc?

#24 Post by **Voltar1** » Fri Oct 07, 2005 11:14 am

I'll see if I can find it. Rule of thumb $$US x two equals deliverd Can$$

Yes, you must know how about refilling co2, especially the safety part comes first. It would be very dangerous for someone who doesn't know the safety precaution. Mind you it's not as bad as PCP rifle that goes up to 3000 psi in the little tube. There was an incident where one of those HPA cylinder blew up in U.K. while pumping and it didn't even reach the spec. capacity yet.
The container or bottle were made mostly to exceed 5000 psi with layers of diff. type alloy that won't split to little pieces if break apart. and co2 only use 900 psi.
I think you're thinking about HAND GRENADE with tiny bits of sharpnel flying in the air and burst out punturing people skin and blood flowing everywhere and building collapsing with explosion and implosion shaking the ground for a couple blocks of the street. ......WELL ALMOST .... j/k.
There is a danger with paintball bottle if the valve head ever let go, it will shoot like a bullet, so far 2 death in US because of that.. I think NO Body here is educated on this, so be careful when next time you're taking the paintball bottle of your gun. Also there is a danger using CO2 POWERLET, if the nipple is ever puncture accidently and knock on the face with it.
Well I guess there is a danger using AIRGUNS.
Nevertheless, there is label on those 88gr. from walmart says NON-REFILABLE, ONE-TIME-USE-ONLY ......AND BUY MORE .....lol...

Safety tips on CO2 bottle.

Always keep your CO2 bottle away from sunlight or any hot object.
Don't leave it in the car on hot day, EVEN Though your bottle equip with SAFETY VALVE.
DO NOT refill your own bottle unless you are certified person .... like me I guess ....lol....but if you really want to, then have a scale that can measure small weight accurately, CT has it. Measure the weight of the bottle before and after. The weight of the co2 fill should not be more than 70% of the bottle spec. but most pro. would fill it upto 80% at paintball store. Filling 88gr. bottle from paintball bottle will only fills 40 to 50%, it's NOT as high pressure you will get as out of the paintball bottle i.e. 9oz. therefore you might notice velocity is not as high as if you would use 9oz, 12oz etc.
No body ever mention this before but PAY ATTENTION when taking your CO2 bottle off your gun or adaptor make sure the paintball adaptor on your bottle does NOT turn loose too as I mention before your paintball bottle adaptor can shoot out like a bullet and can cause death.

DO NOT USE YOUR PAINTBALL BOTTLE IN THE BURNING BUILDING THE FIRE MIGHT KILL YOU.
IF CO2 LIQUID IS PRESSURIZE AT HIGH PSI, IT MIGHT TURN TO ICE.

Are you you certain you know how a liquid refrigerant works?
Some comments concern me.
partial fill of 88 gram won't give as hig pressure??????? wrong. pressure is dependant on temperature and there being any liquid in the container.
As long as there is any liquid and at the same temp. both vessels will have the identical pressure and performance.

DO NOT USE YOUR PAINTBALL BOTTLE IN THE BURNING BUILDING PERHAPS IT MAY JUST REACH 12000 PSI BUT THE FIRE MIGHT KILL YOU.
IF CO2 LIQUID IS PRESSURIZE TO 12000 PSI, IT MIGHT TURN TO ICE.

You mocking me?.......
A full/overfilled vessel of CO2 that has no room for expansion and is heated with no relief provision will escalate pressure to the moon.
You may be certified but it is unclear to me how that happened.
Be careful, Be safe, Be alive.

Sorry Walter, I wasn't intent to mock you, it was only a joke, I guess I should've give a sign ....lol....j/k.

Actually I just got off the phone from the company that supply me with 50 lbs co2 and also talk to paintball city co2 tech. guy..... and I ask them about how much heat does it need for the bottle to go up to 12000 psi and I ask them as if the question comes from me and all I heard is a big laugh on the other side of the phone ...... damn .... they were mocking me...... NOT you.
nuf said I will edit ...my apology ...

Check out the www.warpig.com paintball site with the technical page. Go to the CO2 chart. Look at what happens with a overfilled bottle at elevated temps. The lines on the right 'go to the moon' and I bet the airsource becomes a bomb!!!
You have me wanting to test this theory.
Walter...
BTW no aplogies needed I'm okay, just very serious when it comes to supposed experts passing bogus esp dangerous info. Airguns range in interest from 8 to 80 yrs and so we need to keep this safe.

Phone that company back and ask what pressure will be in a tank full of liquid at 30F when the temp rises to 120F.
Report back how funny they think that is. Lets see if they know their stuff

My 50 LBS CO2 tank has a dip tube and they told me not to worry because my concern would at the back of my warehouse where the co2 tank is, in the hot summer as like a month ago, the room temp. would go up up as high as 38.5 degree celcius = 101 deg. F. I've been doing refill for almost a year now refilling all kinds co2 bottle as well as 88gr. bottle. The trick is always weight the co2 in the whatever bottle and make sure no to fill more than 80% or capacity and I have NOT blown any yet.

My rough guess at 120F IN the PAINTBALL BOTTLE would be somewhere at 2200 psi and safety valve would about to burst between 2200 to 2800 but some safety valve would fail and burst at much lower rate of pressure.
