Omega Help me figure this out

[Solo1]

Just bought a 18 cu ft bottle from aoa. Its the same size as my 100 cu in bottle i got from air venturi. Aoa says it should fill a 580 cc bottle from 150 bar to 250 bar 1.8 times yet when i fill the bottle to 300 bar it only filled a 480 cc bottle from 150 bar to 240 bar? When i ask on the internet a conversion chart comes up and says 18 cu ft is 31,000 cu in ?

Edited to correct size

I need to get my high school physics book, review Boyles Law and then find where I put my slide rule. Are you sure that it's the same size as your "10 cc" bottle? Did you mean to write 10 cu ft?

No its supposed to be 100 cu in bottle and an 18 cu ft bottle

Here’s the 2 side by side it certainly is not 18 cu ft measured diameter both the same

That throws me for a loop also

Equivalent to a 1.6L bottle.

18 cu ft is the max uncompressed volume of air
100 cu in is the actual volume of the bottle

18cu ft is a marketing value that is theoretical. Actually meaningless since it varies with air pressure.

2l Tuxing/Alsafe with a regulated fill valve and boots was under $200.

1 cubic foot is 1728 cubic inches
so 18 cubic feet would be 31,104 cubic inches
so I am confused as to how a 100 cubic inch bottle is that same size?

1 cubic centimeter Is 0.0610237 cubic inches
so a 480 cubic centimeter tank would be 29.29 ( rounding here ) cubic inches

so I am wundereng is the 18 cubic foot tank really 18 cubic feet or is it 1.8 cubic feet that would be 3,110 cubic inches but thats still tree times the size of the 100 cubic inch tank?

I must be missing something on this one?

Theoretical maximum uncompressed volume of air. Just a marketing ploy to make a small cylinder sound bigger than it is.

the math just doesnt add up : ) LOL
