[ThomasT]

Hello everyone,

98ci/1.6L DOT Carbon Fiber Tank filled to 4,500psi

How many times will this tank refill a 100cc , 3,000psi airgun cylinder.

Thanks for the help,

Hello @Firewalker

I tried that and if I entered the values correctly, this is what I got as an answer? It just didn't look right and that is why I posed the question

Thanks you,

That is correct, that tank is too small.

Hmmm, this seems off. I have a .5L bottle I fill to 4500psi and I top off my Airacuda 5 times from 3000psi to 3600psi.

I see what you mean, I tried doing yours and it did not show what it was supposed to.

Hello again @Firewalker

Well that is what I thought, a bigger tank with more pressure ...... . Oh well.

Thanks,

Hello everyone,

OK here is a "copy and paste" from Pyramyd Air web site. The above formula from AOA must be incorrect. Look at the list with 3000psi max fill times size of cylinder, ( example look at Air Force Al Cylinder / 5 Fills ).

Formula is correct. .056 cubic foot should be 16

 

[Sergey1972]

Or some similar number. Cubic inches and liters are water holding volume. Cubic feet are air at atmospheric pressure compressed to the tank volume. From memory 1.5 liter tank has 18 cubic feet at 4500psi, there is a chart somewhere.

 

[Sergey1972]

6.8L tank has 88 cubic feet of air.

Hello everyone,

I went ahead an placed an order for one of these 1.6L Tanks complete with fill valve and dual gauges. This should be perfect for my indoor shooting with my pistols.

Thanks to all who took the time to help with this question
