home co2 filling

[seo_squid]

hi
i need some help, i cant find anywhere near where i live that will fill my co2 bottle, so i have decided to try and fill bottles up at home from a large co2 welding gas bottle, i can get all the most of the bits to make a home filler but cant find an adaptor to go on the paintball bottle. i have seen them on american web sites ( http://www.000paintball.com/index.html?target=p_886.html&lang=en-us ) this is the adaptor i need, does any one know where i could get one?
thanks,
jon

You are posting of Fat Bob's Forum, Fat Bob's is Europes largest online paintball shop.

Here is a link directly to the fill station you need.

Just a quick note though. Welders Co2 is no good. You need a liquid withdrawal bottle. You can get small bottles from BOC

[sonic]

seo you need co2 liquid not co2 gas the c02 liquid bottles have a big white stripe down the side to indecate there is a siphon tube fitted to draw the liquid

thats mhy your bottle is a 20oz bottle because the max it can take is 20oz of liquid c02

hope this make sense and helps

p.s i get my c02 from boc it costs around £50 for a yearly rental and insurance and you get around 12 fills out of a small bottle off them:cool:

If your bottle dosent have a syphon tube just turn the bottle upside down;) .

Err disregard this. A welding co2 bottle is filled with compressed Co2, sure if you turn it upside down you will get a bit of liquid out of it but not much. You need a liquid fill bottle as said before

[Mike]

Hi, could you tell me where BOC is/ or what it is please :D
or how to contact them or Web site?

Sorry to sound stupid

Cheers Mike

[sonic]

boc are the cmpany that supply gases etc heres a link to there web site BOC (http://www.boc.com/index.cfm) :D :cool:

[Azureus]

I get my pub bottles filled at the local fire extinguisher refurb. company and they use liquid, and only £5 a refill:cool: ;) .

[Mike]

ahh thats what it is cheers sonic:p

So what type of Cylinder/tank would anyone recomend, just one with a siypon tube fitted?

would a fire extinguisher do the job?

What about pub bottles ?

Thanks
Mike:D

[beany]

wen you got to get ya C02 from BOC it comes in a cy;inder...then you still ya fill rig on top of the cylinder and way hay fill away...i know ya have to put a deposit down on the bottle for the year then its so much £ for each refill of the BOC bottle....... sonice knows more about it than me i bet she'll be able to explain it better for you........im only goin by what sonic does,,,shes got a fill rig set up :D ......i mean everyones got a bottle of c02 knocking round the house aint they................

[beany]

D'oh i realy need to go back to school for a few days and learn english again.....

[Mike]

If anyones interested heres the prices

Bottle filling economy to those who purge. Purging bottles in order to fill them is a total waste of time and gas. Leave bottles in a freezer ( -18 °C ) for a few hours and they will fill to capacity quickly without wastage. You will need thick gloves when handling but well worth the time and gas it saves. An 'O' ring in the bottom of the filling donkey will improve the seal. Put bottle on scales during filling as it is easy to overfill.

[Fusen]

is that last comment true? about leaving bottles in -18 to refill?

[Bill Bailey]

I have been using this method for many years to fill bottles efficiently. The physics behind the behaviour of CO2 is not simple but if you start at a low temperature the heat generated by the increasing pressure as the bottle fills goes into to heating the bottle itself as well as the gas. By the time the temperature has reached around zero ( when the bottle starts to defrost ) the bottle is pretty well full.

When you purge a bottle you are effectively quickly freezing the inside of the bottle to -20°C or less. Using a freezer does the same job and takes a bit longer but does not waste any gas. I have shown this trick to many sites sites locally who now adopt this method. It is prefectly safe as long as you take normal precautions when dealing with supercooled equipment.

Gas physics is not as dull and useless as you might think !

THE TRICK ABOUT PUTING THE BOTTLES IN THE FREEZER REALY DOES WORK AS THIS IS HOW WE FILL ON SITE WHERE I WORK

[FaDeH]

really ?

So what actually happens ? do you fill it up with gas n put it in the freezer or just leave empty cealed bottles in the freezer ?

Yeh thats right im a super newbie

[Bill Bailey]

Well, FaDeh, if you read the contents of all the messages you would know exactly what happens. So - to put it very simply you put the empty ( or part empty ) bottles in the freezer. Wait for a couple of hours to freeze fully, take them out and fill them.

I am not sure about your reference to cealed ( sealed ? ) bottles and common sense should tell you that there is little point in filling the bottle and then puting it in the freezer !!??

If I have missed anything please ask again.

[FaDeH]

miss key on sealed.

I understand about the freezing n why it could happen but i didn't realise that it is successful.

Common sense did tell me that there was no point filling it up totally and putting it in the freezer unless it was for a longer storage solution....

I understand fully on this technique now, cheers.

[nick ryal]

remember when you fill the bottles not to over fill the bottles. try to weigh the bottle empty and then as you fill

[Bill Bailey]

Sound advice Nick. This is my method. Get a completely empty bottle ( cold ) and connect it to the fill station. Place it on a suitable set of scales on a cloth to stop it sliding around. Fill the bottle until the required amount of ounces have been pumped in. Make a note of the final weight.

From now on all bottles ( of the same size ) when full will reach this weight. So any bottles whether empty or part full can be quickly filled simply by filling them to the same weight. As a typical guide all my 12oz bottles weigh 25oz when completely full. Note this is 12oz of gas plus the bottle plus the fill station pipe and donkey.

True there are slight variations in bottle style and shape but this method will be sufficiently accurate within an ounce or two which will not pose a hazard. I have filled bottles to 15 oz inadvertantly without problems but I don't make a habit of it and I would not suggest doing it to get extra capacity. Burst discs do work !!!

[nick ryal]

this is a good method of filling .it also means that you can make a note of the full bottle weight and if like us on the site you simplly weigh the bottle to see how full the bottle is.
just remember if you are using an antisyphone tube in your bottle(a pipe that lets you fill with liquide but only draw off gas)that you cannt fill with the correct weight. we use 20oz bottles with antisyphone tubes and you should only fill with 16oz, i am not shure about the fill weight of a 16oz bottle with a antisyphone tube if you know let me know thanks.

[Bill Bailey]

I don't use bottles with antisiphon tubes but I can see the snag. The tube effectively only allows the bottle to be 1/2 to 3/4 filled. Any more and the liquid gas level is above the level of the tube so liquid will be drawn. There is a solution to this problem but it is specific to each gun/bottle and probably not practical for general site use.

The method I used was to put a bend in the siphon tube so that when the bottle was fitted to the gun the tube was effectively up against the upper surface of the bottle. Unless the gun is pointed upside down the liquid gas level will tend to stay under the end of the tube. True, this is not totally fool proof but if you can avoid tipping the gun down when firing the system works. What you need to do is unscrew the valve from the bottle and screw it into the donkey on the gun. With the gun upright bend the tube upwards as far as possible so the bottle will still fit on. Shortening the tube will help or fit a short piece of plastic tube that can be bent. Refit the bottle to the valve. From now on with this bottle on this gun the antisiphon tube will be above the liquid level thus allowing more gas to be filled. It would be worth marking the bottle with the position of the siphon tube so that when it is fitted to any other gun you can tell where the tube is pointing.

It is preferable to use a bottle with an on/off valve for this. If you use a pin valve valve there is a good chance that some liquid will be drawn during the fitting of the bottle. This may or may not be a problem.

As far as bottle weights go as long as all the siphons are the same, trial and error is the only way to establish a "full" weight.

Very Old...:D

One day someone will give me the rest of the song - maybe. ;)

[Eric]

doesnt use that much gas! less expensive than buying a huge industrial freezer to freeze all the bottles for filling, and using the next day! or do you just do it for 1 or 2 bottles for yourself or what?

[Bill Bailey]

Well Eric, you seem to have a rather distorted perspective.

Purging requires at least 2-3 oz of gas for 12oz bottles to be effective and more for a 20oz. That equates to at least 25% of its capacity being thrown away. The average price of a large K bottle is around £20.00 so you are throwing away £5.00 for each bottle you buy ( or refill ). A freezer costs less than £5.00 a month to run. If you are a site operator using a serious quantity of gas £5.00 per bottle is a lot of money. A second hand chest freezer will hold up to 40 12oz bottles and they are not expensive. ( they are not that expensive new ! ) Why bother with an industrial freezer ? At worst I might have to do my filling in two batches but that's still better than chucking money down the drain. You will soon recover the cost of a freezer and from then on its all money saved and money in your pocket.

Obviously for a private individual purging is more convenient and I certainly wouldn't waste time freezing one or two bottles. When you are dealing with 40 bottles or more at a time the cost and time become quite significant.

I suspect all of us learned to fill by purging. Those of us who have to do it for a business have to consider the implications of the costs of such procedures. Anything that saves money and makes life easier has to be worthwhile. - unless I am missing something.

[nick ryal]

i total agree. we can be filling up to 120 20oz bottles a day at thew weekend so purging is very expensive way of filling for us.
we run a large chest freezer for keeping the bottles in for next to nothing.
i now it may seam like penny pinching but it saves on gas cutting overheads and keeping it as cheap as possible for you to come and play on our site.where the money that we can save is put in to developing new game zones.

Does anyone still use Co2 any more?

Yes, i use it in my welder.
