Scuba cylinder breathing air quality for divers

Air (Oxygen) is the single most important thing to a diver when scuba diving. Whether you are SCUBA diving for fun or its your profession, the last thing you want to worry about is your compressed air quality. Our brand new Bauer Mini Verticus MV250 high pressure compressor is a newly designed field-proven system that sets the very highest standards in technology and air quality and purity.

We also ensure breathing gas quality by using a Bauer B-Securus filter monitoring system.

The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the residual humidity of the compressed air in the molecular sieve of the P-filter system and outputs an "advance warning" on the compressor control display,  indicating when the filter cartridge(s) should next be changed. 
The service life of the cartridge(s) cannot be exceeded because the advance warning signal draws attention to the saturation of the filter cartridge(s) in plenty of time. The B-SECURUS filter monitoring system ensures that the compressed breathing air is as clean as possible and in accordance with DIN EN 12021 and Worksafe/Air Purity NZ.

All our high pressure breathing air is tested/analysed every three months. We analise levels of Oxygen in our breathing gas and test for levels of carbon monoxide, carbon dioxide, water vapour, oil mist and odour. Our air quality test certificate is displayed in store for your perusal.

TIP - Make sure you use a reputable Fill Station that proudly displays their current Gas Purity Test Report (As we do).

Safety is in the air!
