when comparing tanks keep the units in mind.
Pressure is measured in PSI (or Bars, atmospheres) and a volume of air is measured in CF (or liters).
PSI's are not a measure of volume.
If i know a tank has a pressure of 1500 PSI it tells me nothing UNLESS i also know what volume of gas the tank holds at it's rated pressure.
for example:
(ideally);
a HP steel 102 @ 1400 psi, an AL80 @ 1500 psi and a LP 104 @ 923 psi all hold roughly 40 CF of gas.
where HP is 3500 psi, LP here is 2400 psi and the AL is rated at 3000 psi.
make sense?
