I doubt it. I think more along the lines of a Paslode's fuel cells(small cylindrical cans of compressed air).Then it would need a battery as well to provide the ignition mechanism.
The second ones Olaf posted look to me like they work more like a powder actuated tool-using a blank cartridge to propel the pin or in this case bolt.
From what I read while researching most pneumatic spear guns just use regular compressed air and are charged by either a hand pump or a scuba tank mainly which ever you felt like using.
