CYLINDER GAS FILLS
Need gas for your next diving adventure? Vobster Quay is home to a state of the art compressor station capable of delivering air, nitrox, oxygen and trimix fills to a maximum of 230-bar pressure.
All our air is filtered and tested regularly for impurities so you can be sure you'll always get a fill of the highest quality. With a plentiful supply of filling whips available, waiting times are kept to a minimum.
For nitrox and trimix divers, Vobster is home to a state of the art partial pressure blending system. Our skilled blending technicians are on hand at all times to ensure you get the gas mix you want. For rebreather divers, air or trimix diluent and high pressure oxygen to a maximum of 230-bar is also available.
PLEASE NOTE: All gas prices listed below are correct at time of publication but may be subject to change without notice.
Important Information
- All cylinders must have a valid and in-date IDEST blue or green quadrant INSPECTION TEST STICKER in line with current HSE guidance.
- Please note that in order to purchase nitrox or trimix cylinder fills, all divers must produce a VALID CERTIFICATION issued by a recognised diver training agency that is appropriate for the requested gas.
- As we use a partial pressure blending system for nitrox and trimix fills, your cylinders must be both OXYGEN CLEAN and in OXYGEN SERVICE if you require us to fill them with any gases other than clean air. They must also feature a valid and in-date OXYGEN CLEANING & INSPECTION sticker issued by an IDEST test centre.
