Does the C02 have to be beverage grade or can it be from a welding or paintball shop?

[naser]

i would imagine that all co2 setups are the same, and in the same sentance if im wrong that the beverage co2 might be cleaner for human consumption? might be a higher grade or cleaner co2.. not sure though.

I asked one of our CO2 delivery drivers about this a few months ago ( I work in a Coke lab) He said beverage grade and welding grade were the same, 99.9% pure....

I'll ask again to make sure.

Got mine from welding shop NP 10bux for a 5lb bottle fill

i was wondering about this myself.ive played paintball for years and its pretty common for the co2 to be "dirty",with alot of foreign debris.chunks of metal even get in the gas(i i guess from threads getting "chewed"when filling).im sure the gas is the same but what about how clean it is,i would think a beverage grade would be preferable(welding shop sounds dirtier than a paintball shop).

Same supplier using the same gas often supplies printers, welders, and fountain operations. This is true here in Nashville.

I read that same comment about it being better to use "beverage grade" CO2 in an article by one of the hobby authors. Most people get their tanks refilled at welding shops. In fact, you can get a 5-lb bottle refilled for only $5 in Baton Rouge at a local welding shop.

I think the trick is to get your own brand new bottle and then just keep getting it refilled instead of swapping out bottles every time. I believe the guy who wrote that article mentioned something about moisture and impurities being a concern with tanks from welding shops but I think he was thinking in terms of just swapping out tanks and using their old, beat up tanks instead of your own nice new tank.

I'm moving this thread to the Tanks, Filtration & Basic Equipment forum.

My buddy owns a shop. They fill welding tanks,beverage tank with the same co2. Dunno if there different but they also fill different gases for dental offices. I don't know what the differeces are but they fill many types of gases= all from the same supplier.

Dentists use N2O, nitrous oxide. I just had a pulmonary function test last month and they actually use a combination of carbon monoxide and helium to test diffusion. Fortunately they only use 0.3% carbon monoxide combined with 10% helium.

i dont have a ca reactor ,do you guys have a little screen to act as a filter on you co2 tank?i always use one for my shocker(paintball gun) to prevent debris from getting in the gun and causing a leak by displacing an o-ring.ive pulled numerous metal chips out of my gun.i wouldnt want those little metal chips to end up in my tank!oh and i always use my own tanks,and i even have a 50 lb co2 tank with a fill station(so me and my freinds can have private games)and dirty co2 is just a problem that all the players i know have always dealt with(since we started using refillable tanks that is).has anyone even considered dirty co2 ?

[Nanook01]

What happens when your tank is expired and due to be tested? Does anyone know how much this costs?

Ok, I talked to our local CO2 supplier today, he said the CO2 you buy at your local welding shop SHOULD be a better grade of CO2 then the bevarage grade. He also said it all comes off the same line.

This info came from BOC gases So Cal.

Just wanted to add that I tryed a new approach today and got a 50# cylinder for a rental fee of $60.00 + $19.00 to fill. Thats it. Should last atleast a year.

[organicreefer]

golfish,that may well be true,but what about those little metal chips?i doubt you'd find those in a beverage grade(maybe they use a filter/screen,or have some way of keeping foreign debris out).i guess no one hear has any exp with dirty co2.

any other paintballers wanna back me up ?
id like to get a ca reactor and i think ill use a beverage grade or at least filter it with a screen

[golfish]

organicreefer,
The metal chips have nothing to do with the quality of the Co2.. My guess is there coming from the tank. We use probably 50,000-100,000 lbs of Co2 a day at the Coke plant I work at, I don't recall seeing any kind of Co2 filters. There maybe some though. I'll asked around at work tonight and see if we have any. If we do I'll check to see if theres any kind of metal chips trapped in em,

Cool! Hey Coke Man is there anyway you could mess around, and have a lot more caffiene go into the mixture? Or prod around at the "big wigs" the idea of increasing the caffiene input? I'd love ya for it

Copst on hydrostatic testing will vary from state to state. But be warned that the bigger the tank, the bigger the cost!All welding shops and Fire Extinguisher companies should be able to perfom this test for you. Make sure they use .... forget the actual term...... the submerged water jacket test. This test should on average take 3 days. ! day to fill it with water, you do this to let the pressure and temp. to equalize inside and outside of the cylinder. day 2, or very end of day 1, submerged in to the jacket and pressure tested. once it is removed it should be placed on a dryer until completely dry on the inside. Then you can pick it up at end of day 2 or day 3.
If you go to a company and they say they can do it in less than 1 day, you are getting cheated out of your money and being put in possible danger. If they say it is good and havent tested it, when those valves and or necks decide to blow off, some one will get seriously hurt or worse.
Average price for a 5# co2 should run you around5-12 dollars, plus the cost of a refill, usually around the same price. But do not quote me on these prices for the companies that you may find.
BTW, if you have a Grinnell Fire Protection company in your area, they are a good quality company to use.,

Mark,
Jolt cola comes to mind It would be very easy to do but what about all those little kiddies.......

[organicreefer]

golfish i said that i agree the metal chips dont have anything to do with the "quality"(wasnt even aware there were different grades) of the co2.the metal chips come from the ENVIROMENT where the bottle was filled(there are plenty of metal chips in a welders shop ,i would imagine).i usa a simple metal screen(like for a faucet)to catch any debris,and trust me theres plenty.i think that co2 for beverages would be filled in a cleaner enviroment,and probably be alot cleaner.
