Air, Nitrox and Trimix

Air fills 

Air is available to 300 bar. Our air exceeds current requirements for recreational and technical diving. A certification of analysis is displayed in the shop at all times. The filling of cylinders is done so under the guidelines of HSE and only cylinders conforming to these standards can be filled on site.


We are also offering our Loyalty Air Card which gives you two free fills with every Air Card.

Nitrox fills

Nitrox is available from 22% through to 99%. Cylinders have to conform to HSE specifications. Customers will also need to bring their certification for their first nitrox fill. Nitrox can only be issued to those people who have proof of certification and only fills to that level can be taken.


Please remember to bring your certification with you for your first fill. This will allow us to add you to our database for future reference. Gas can only be signed out if an appropriate certification is provided. We reserve the right to charge for any gas which has to be drained due to customers not being able to provide suitable documentation. 


Failure to pay for gas drained will mean cylinders being retained until the matter is resolved, the gas has been paid for or proof of certification is provided. Cylinders may be sold to recoup costs.
