Air Compressor to CO2 bottle

[Ric]

Ive heard or read somewhere that its possible to fill your CO2 at home, using your garage air compressor.

Is this possible ? Im thinking it would be, BUT you would only be able to fill the CO2 bottle to 120 PSI or what ever the air compressor is set at..
Is this even worth the trouble getting all the corect fitting ?

yea, i know NOOB :tongueout: :D

I'm sure it is possible.

Personally, i'd say way more trouble than its worth. But I am biased toward CO2, as i think it is the greatest thing since sliced bread.

What i would suggest is this:

Post up what size tires and rims you are running (width and height). Post up the size of your CO2 tank.
Post up what you usually air down to (as close as you can tell).

Then, we'll see if we can't figure out if you can air up four tires with the garage charged tank. If you can, then go for it and buy the fittings. If you can't, don't waste your time.

not worth the trouble............ CO2 when filled is in liquid form at 850 psi. Filling the tank with compressed air to 120 psi wouldn't even fill a single tire....

Thats what i was thinking, but wasn't sure, and figured we could calculate how much air you could get out of one tank.

Thanks Bruce, that will save time.

thankx for the replies.. and Bruce, thats what i was thinking, but didnt know for sure..

put it this way an average SCUBA tank hold 80 cu ft of air and they barely fill all 4 tires, that's 3000 psi.........

If your lucky you'd get maybe 2 psi into the tire.........

wooow, well now i know, lol i thought it was to good to be true..

bruce i know with my scuba i've filled at least 5 vehicles back up most scuba tanks have 3000 psi as far as i know most co2 tanks are about 2200

[BruceTS]

As long as there is liquid in the tank, the pressure in a CO2 tank is determined ONLY by the temperature. At room temperature (70 degrees F) its about 853 psi.

As for a SCUBA tank it depends on the size of the tire and how low the pressure was to start and what pressure your going to.

[wifesaysimadumbass]

i know for sure that my 33s that i would run between 8-10psi i could always fill my rig at least 3 times on one tank

Speculative SCUBA anecdotes are blurring the issue here.

A CO2 tank could only be filled to as high a pressure as your home compressor could put out which would not be enough to take care of tires.

SCUBA tanks are extremely high pressure air stores. Because they do not rely on the phase change, they are pretty inefficient.

There is CO2 and there is everything else.
