CO2 tank mounting ideas

[KeithS]

It seems peculiar to make the observation, but a CO2 tank can hold air at the same pressure, produce the same benefits in terms of airing up tire and running an impact driver, and do so without any of the drawbacks.

If there is an real benefit to CO2 over air I'd love to hear it.

I opted for an air compressor myself, but I know from past research that CO2 has a volume and speed advantage over air. Even if stored at the same pressure, a CO2 tank will contain a larger volume of gas because it is stored as a liquid in the tank. In order to match the speed of a CO2 tank you would have to use a scuba compressor and scuba tank or something similar (way beyond the pressure of a normal shop air compressor).

I have learned something. I did not know that CO2 would change state at 800 psi. I understand the advantage in terms of gas volume now.

However, I would still not make a practice of airing up tires with CO2.

You mention tracks in the bed. Are you talking about something like what I have installed?

I'm looking to mount tracks to the sides of the bed.
Hi-lift, Powertank, and Rotopax is what I plan to mount to them.
I'm just not sure how I want to do that yet.

the tracks you have in the floor are something I am considering in addition to what I end up running on the sides. I looked at your pics last night. nice mod for sure!

Hmm I'd be leery of tracks mounted to the sides who's job it is to support all the weight you're talking about. Maybe think about making your own mounts and using tie down spots instead? Something like this: http://www.fordraptorforum.com/f11/hilift-jack-mounted-bed-tons-o-pics-10102/

I have been doing this for years. It will not be corrosive to your tires.

dirrect from PowerTanks website:
"Yes. CO2 vapor is inert (non-toxic, non-corrosive). CO2 vapor is perfectly safe for your tires and wheels"

For those that do want to learn more on CO2 tanks, here is a dirrect link to PowerTanks website.

PERFECT for the Hi-lift!
I'll end up making a wider bracket and mount it like that. I think spreading the weight over a larger area will work well.

The PowerTank may need a bed rail to floor mount brace though. I'll play around with it more once I get the BAKflip rails in place.

Timco, you need to be conscious of the source. Powertank wants to sell you their product, so it is incumbent upon the consumer to beware of advertising hype. As the old saying goes, "Let the buyer beware."

At this site Carbon dioxide you will find this: "Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable."

Powertank's use of the word "inert" to describe CO2 is patently erroneous.

So mr Ruger, have you ever had a propane tank for house heat ? Propane is -44 degrees if I remember right. It is in a Liquid state at that tempature in your propane tank. It warms and Vaporizes, the propane Vapor is what you burn.
Co2 is compressed, then cooled, compressed, then cooled. So as a "cold liquid" more goes in a bottle. As it warms it expands filling a tire faster and with less Co2 "cold liquid" used. Air compressors create Heat. The Co2 bottle is filled at a plant where you will never see the process. I am about to learn Much more about all this hopefully very soon. I think I got my process/facts right.

^ No, I've never lived in a house with a propane tank.

So what? Gases have very different temperatures at which they change state. CO2 probably isn't comparable to propane or very many gases at all because of the rather mild temperatures at which it changes to a liquid and then to a solid (dry ice). I do understand the gas volume logic, and so indicated previously. I just don't think it's wise to put a mildly corrosive gas into the tire envelope where it could eventually compromise valve cores and/or the tires themselves. Tires, wheels and valves are designed to work in air, and I won't be changing that on my truck. Do what you will with your own truck.

Technically CO2 is not acidic as it contains no H+ atoms. However it will turn water slightly acidic when exposed. Don't take that as means it will be an acid, it's simply slightly acidic (just like almost all water that touches your tires). It won't have a reaction with your tires.

On another note CO2 is in the air that you regularly fill your tires with.

Just make sure you keep Dihydrogen Monoxide away

I was trying to use a gas more are familiar with to paint a picture.
How about a nitrogen bottle ? Not sure how many tires you could fill with. The same size bottle ?
