CO2 is generally marketed in a lower pressure, 850 to 1000 psi, depending on outside temperature, while a similarly sized air cylinder will contain anywhere from 1800 to 4500 psi, depnding on it's rating. Because of this, you will get significantly less cubic feet of pressurized air in a CO2 cylinder than a similarly sized air cylinder. Saw the damage once, from where a well-meaning person obtained the necessary adapters (CO2 and air have different valve configurations to prevent cross-filling) and filled a CO2 cylinder with 2216psi of air (the PSI rating for many fire service air cylinders). The damage wasn't pretty, but fortunately noone was hurt.....
