On-board CO2 tank

[akwheelin78]

So I finialy have all of the parts for the 20lb CO2 tank that I picked up last week. I only know of one other guy that has one but he claims that he can fill his 44" AGs 20 to 30 times off of one tank... The tanks themselves are very easy to find, any welding shop (weld air, airgas, air liqued ect) will have them in stock. A CO2 regulator that meets the needs of the off road driver was a little more difficult. After spending a day driving around Wasilla and getting nothing but blank stairs from most people I ended up in Anchorage at Airgas. We spent a while looking thru the books and the only one that fit the bill was made by Victor and the only ones were in Indania an there plant. So with UPS blue it got here in 3 days. The regulator will handel the 850psi on the tank side (I was told that a 20lb tank holds 120 cubic feet) on the low pressure side it goes from 10 to 400 lbs! Way more than needed but whatever. I aired down one of my 35" boggers and set the tank at 200lbs on the output side. The tire was back up to 35lbs in less than 15 sec...wow! An exchange for the tank is around 30 bucks in Wasilla.

wow... lets do one of my boggers for good measure. I already have one off :smash:

A few pics of the set-up.

I'd love to have the specifics on on the preasure regulator. Mainly brand and model number. I have a feeling this is what is going to end up on my rig for the time being.

It is made by Victor, they make all sorts of gas regulators. This one is called "Victor Edge series high flow CO2 regulator" and if I am reading my recipt correctly the part number is "0781-5147"

I have a divers tank and regulator which I had hydro ed, if any body is interested. it holds 2300 psi of air. can get refilled at the dive shop in wasilla.

I have filled an ag up probably 15 times before I switched out my tank. Have yet to completely empty it, I just refill it every year before Eureka. Its awesome just to have around the house too. I just used a generic 90 psi regulator, but definitely want a high flow. Powertank has a 150PSI non adjustable one with no gauges for about 100 bucks. Suppose to be pretty high flow, and durable.

How much did that regulator set you back?

I can only fill my 38s up twice with my 20 LBS CO2 tank... Damned Street tires.

Oh well I got a York thats goin in this year. Or maybe I'll just mount Sarah Palin under the truck, then I'll have an unlimited amount of air...

X2 i have a 20lb tank sitting around out of a kegorator i need to repair would be cool to setup one co2 tank to fill the tires and dispense the beer!

when wheeling in fairbanks few years ago i could not get mine to work in the cold .. it would have no pressure and valve would freeze trying to rebead a tire .

in the warm weather they work great no so much when freezing .

It was 245.00 at airgas... dont know how good of a deal it was but all the specs were right. Varyable output pressure and very high flow. I found others in Wasilla for around 80 bucks but the pressure only went to 60psi and the flow was very low... also all made in china.

[akwheelin78]

As far as the dive shop tanks yes you may be able to get 2300psi of breathable air in the tank but how many cubic feet is in that tank. Breathable air like that is a gas where CO2 is a liquid like propane. Yes there are some cold weather issues but you can get a lot more into the same space. I was first looking at nitrogen, a gas that has more of the desireable traits for use with tires but could only get 40 cubic feet at over 2000lbs into the space of 120 cubic feet of CO2 at 850lbs.

[ryantowry_81]

a lower flow regulator would still work just not at the speed of the higher flow versions. what is the CFM on your regulator?

[akwheelin78]

Victor only shows a graph chart with flow vs. tank pressure. you can find it on the website...

I did 30 years in the fire dept. Those fire ext. you see around buildings about 2 feet or so, are 15 lb ext. meaning they hold 15 lbs of co2, if i remember right its stored at 0 degrees in side tank, comes out at 110 below. In a warm building it has more pressure, out side it will have less pressure. If left in a hot sun, it can blow the safety disk and bleed the co2 off. Those ext. used on the flight line held 50 lbs of co2. I think we used to put nitrogen in the ext. to winterize the valve and stabilize the co2, also to give pressure to expel the co2. Next time you have it filled ask about having nitrogen added.
The military did away with co2 exts many years ago. probably may find a few down town still. Back in the 50s we had a crash truck that carried 12,000 lbs of co2, the top boom put out 1200 lbs a min. the bumper ply pipe 650 lbs, and the 2 ply pipes which fireman carried put out 650 lbs each. In the early 60s, this vehicle was replaced with a faster and lighter one that carried 6,000 lbs of co2. It had the same boom and play pipes, didn't put out as much co2. It didn't take very long to empty either vehicle.
I'm going to check with the dive shop on SQ-feet in this large tank.
