- Owning a SCUBAPRO dedicated Nitrox regulator means you can
safely dive using oxygen enriched air with over 21% and up to
100%
oxygen concentration at a maximum working pressure of 200bar, in full compliance with EU norms EN 13949:2004 & EN 144-3:2004 for breathing devices. - SCUBAPRO Nitrox dedicated first stages have specifically designed connections for Nitrox cylinder valves, which differ from the connections for standard compressed air cylinders.

- Our Nitrox systems only use approved and specific oxygen compatible components (HP seat, O-rings, washers and grease) required for high pressure oxygen systems for guaranteed safe diving.
- SCUBAPRO Nitrox regulators are assembled in a dedicated environment with the required level of cleanliness for oxygen compatibility.
- Nitrox regulator systems are easily identifiable with green color accents.
- WARNING: if a Nitrox dedicated SCUBAPRO regulator has been used with standard compressed air it is then compulsory to perform a new maintenance and comply with the cleaning procedure specifically designed for the use of nitrox mixes and carried out by an Authorized SCUAPRO technician, before using them again with Nitrox.
