If I where to get a 68/3000 for my wrath and use my 80cuft 3000psi scuba tank to fill it, How many fills could I get out of the scuba tank before having to refill it?

Thanks

only a few full 3000 psi fills. you should have gotten a 6000 psi tank.

 

[hankyfied]

it should work out like this: 12 ci in 1 cubic foot, so 80 cubic feet times 12 = 960 ci

so 960 / 68 = about 14 fills , the math is rite but i dont know if it works like that

Does anyone use a scuba tank to fill their hpa that can say for sure?

 

[THE DRG]

Hankyfied, I think there are 1728ci in a cubic foot (12x12x12). 1728ci x 80(cubic ft) = 138,240 ci in 80 cubic feet. But I don't think you can figure it like that. Like George said, if the tank has 3000psi in it and you fill your tank, it won't have 3000psi in it anymore. only allowing a few fills. So, George, a 6000psi tank is better? How many fills would you say you could get from that? Can anyone else help. Does anyone use scuba tanks?

I use an 80ci/3000psi SCUBA tank. I usually get 1 or 2 good fills to 3000psi. After that it starts tapering off with each fill. I usually get about 15-20 decent fills. When it gets down to about 1500psi or so I usually refill it. And for $4 to fill the SCUBA tank you can't beat it.

Be sure to see if you can even find someone that can fill to 6000psi before you toss the extra money into the tank that can hold it.

Hey, Xmagman. Did you mean you use a 80cf/3000psi scuba tank? What size is you marker tank?

Yea, my bad, I meant an 80cf/3000psi SCUBA tank. The two tanks I have are 68/3000 and 68/4500. I get pretty much an equal amount of fills in both.

Thanks xmagman, It sounds like buying a scuba tank would be a good investment, and I am a certified diver so getting fills would be no problem. Thanks.

if you get a 6000psi scuba tank you will need a different fill sation on that tank instead of a 3000psi tank, so that you arent risking blowing your tank when you try to shove 5000psi into a 4500psi tank

 

[intotheflats]

I am going to get a standard 3000psi scuba tank, I looked for 4000psi or higher but they are really hard to find. Plus I could actually use a 3000psi tank for diving without having to buy a new dive reg.

who mentioned 6000psi anyway, I never did

Actually you are off a little. A cubic foot is 12x12x12= 1728 cubic inches in a cubic foot. So there are 138,240 cubic inches of air in a 80cf scuba tank at 3000psi. 1 cubic inch equal 16.387064 cc so a 80cf scuba tank holds 2,265,347.7 cc's of air at 3000psi.
But I still don't know how many time you can fill an 180cc tank to say 2800-3000psi before you would want to have it refilled.
