The noble gas Argon (Ar) can be filled to pressures up to 180 – 200 bar (2,610 – 2,900 psi). Because Argon inside iSi Components Gas Cylinders exists in its gaseous state, it is a suitable gas for cold-weather applications or where high pressurization may be necessary. Users can expect less expanded gas from an Argon-filled cylinder compared to that of a similar size Carbon Dioxide- or Nitrous Oxide-filled cylinder.
