Oxygen can be supplied up to 230 bar providing the cylinders are in current test and oxygen clean. Either a suitable diving qualification or oxygen administration certificate will be needed to obtain these fills.

Please bring your certification with you for your first fill. This will allow us to add you to our database for future reference. Nitrox and Oxygen can only be signed out if an appropriate certification is provided. We reserve the right to charge for any Nitrox or Oxygen which has to be drained due to customers not being able to provide suitable documentation. Failure to pay for Nitrox or Oxygen  drained will mean cylinders will be retained until the matter is resolved.
