Series-O Nitrous Regulator

The Series-O Nitrous regulator has been the industry leading regulator in Australia for years. The simple but effective design and ease of use make this single stage regulator a very low maintenance yet high performing product: one that can be used in dental environments.


  • Large diameter diaphragm gives a performance that is normally only found in double stage regulators
  • Triple filter system increases the regulator performance by preventing foreign particles from getting in contact with the high pressure gas or the regulator seat
  • No tools are required to routinely disconnect the regulator from the cylinder valve
  • A safety relief valve is built in to the regulator to protect staff and patients in the event of high pressure failures
  • Tamper resistant design to ensure only qualified personnel can access the regulator
  • Colour coded pressure gauges and identification labels for quick recognition of the gas used by the regulator
  • Gas specific inlet fittings and outlet fittings to prevent fitting to the wrong gas type
