Re: SCBA Tank for On board air?
I am a certified diver also, so filling the tanks was not a problem. I used a fresh 80 cubic inch steel tank, while wheelin with a bunch of guys from 4 Wheel Parts Wholesalers in Reno, Nv, last summer. We were all curiouse to see how well the set up would work. We used it on the trail to re set a bead on a 33" tire(the re set went very smooth, with maybe 15 seconds of full pressure blasts with the valve stem removed from the tire), and filled it back up to 10 psi. There was not enough air left to fill my (4) 35" tires from 4 psi to 25 psi, on my rig.
Its not like I havent tried using a scuba tank, we tried it a couple more times, but again, 1 tank could not fill a full set of 36" tires, when the tank was used for about 10 minutes of impact wrench and air rachet, repairs on the trail.
If your OK with that type of capacity on the trail, and have a PADI card, its very convenient method and only costs a few bucks per tank. But it is probably not 1/4, of the stored energy you get in a similar sized CO2 tank. There have been several comparison tests (although biased towards the "Power Tank" CO2 systems they are trying to hard sell), in the variouse off road rags, with similar results, Im sure someone could post.
