KS/MO CO2 or Power Tank Fill Up

[2fpower]

Found this thread....

here is the skinny.....

Like you said, you can't convert them to CO2. They are designed differently. The difference between CO2 and air tanks is the pressure inside. CO2 will only get about 900lbs (IIRC) of pressure as opposed to the 4500 that the air cylinder will. A puncture on a CO2 tank will not catastrophically explode like an air tank will. For this reason, many people shy away from high pressure air. The other down side is, an air tank will only fill up 3-4 tires depending on tire size. A CO2 tank can fill as many as 12-15 tires.

Like you, I can get surplus cylinders at work, and I can fill them for free. But, the downsides just aren't worth it for me. If you haven't seen the video of the Detroit fire engine that had a cylinder explode (probably 4-5 years ago), you should look for it. The damage was pretty impressive. Luckily, the rig was sitting in the truck bay and no firefighters were in it at the time of the explosion. For $150 or so I can get a CO2 setup from the local Airgas (I got the quote, I just haven't pulled the trigger yet).

Good luck!

I pulled out one of the scott air system delivery regulator things last night. wondering if we can take these apart and somehow use them to regulate the airflow. Just need it to push 40psi for inflating tires.

Any word from the SCBA tech?

I go back tomorrow and hopefully he will be stopping by our station so I can pick his brain. It looks like you already have the tank valve in place ( bonus ) and I know for a fact you can adapt down to an air chuck from that, just have to find out threads and what not.

Sorry to be a jerk. I don't get the math. I know we all like to modify stuff here but why not get a legal co2 tank and call it done. Equipbid has two listed right now going for $15. A $20 fill and a regulator and your done.

Is this for everything needed? Tank? If so I would be interested in one of those setups for that price.

There's no math involved. The Scott SCBA cylinders are extremely top quality, they have to be because people literally stake there lives on them. The original question was, can we convert one to a CO2 tank since it seems we have a supply of readily available, top quality pressure vessels. I'm still not sure I understand why these can't be used. The system pressure shouldn't matter. If its 900psi in a bottle designed for 4500psi its still going to come out. The only difference I see between these and the powertanks are the size, with the Scott looking to be quite a bit larger which I think would be a bonus.

@2fpower I will have to ask the tech if he ever comes back, but I'm not sure if exploding would be an issue with the newer carbon fiber bottles. Not that they wouldn't rupture, but even if they did, at full air, I think they would just turn to fiber. Now the old aluminum and steel bottles could go off violently. Any of them would have to take a heck of a hit though. We scratch and bang them off of everything at work and never had one let go. Some of them get pretty big chunks knocked out and they just get taken out of service.

Yeah, but I am with Erik on this. Dollars spent for real thing is not much vs. the risk and hastle. For under $50 get a real CO2 bottle, no questions asked when you swap them out or get them filled.

I will use my scott tanks for on board air tanks when I find a mount for the york compressor.

I remember hearing the story of a guy taking some acetylene from a friend, and put it in his tank, not specifically made for acetylene. BOOM on the way home.

Can't find that story, but here is a pic of the power.....

Just realized the price was from the other thread. I can go to Airgas while at work. I might have to stop by there and see what the current cost would be for a setup.

Needing something before CO next month. If you guys find something reasonable let me know.

Just fyi. There are many sizes of co2 tanks. From paintball. To ten lb to twenty and up. Chef used to run a ten lb in his truck to fill ties and run arb. Smaller than the twenty I use on my welder. U can swap sizes easily

 

[half k cruiser]

Are these basically just welding bottles that you can pick up from Praxair ?

 

[tornadoalleycruiser]

Yep. Welding and kegerator. Same stuff. That's why I have spares

I have a 20lb from one of the big name gas suppliers my friend works for. they set up mine with a 100psi constant pressure brass and quality valve/regulator. I have gone from 18 to 35 psi in 285/16's about 24 tires worth plenty of gas left. You need to be sure and use green freeze tolerant line and then into a 150 psi yellow coil and you can reach a long way. I could possibly set up a bulk purchase of tanks/valves/reguators, and gas for the club.
