MK25 NITROX

MK25 in a Nitrox compatible configuration satisfies both advanced and recreational divers.

• 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. This ensures utmost safety and no risk contaminating Nitrox with potentially hazardous hydrocarbons or residues.

• 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 & yellow color accents.

• WARNING: You must be fully trained and certified by a recognized diving training agency in order to dive with oxygen enriched air (Nitrox breathing mixtures). Diving with Nitrox without such certification could lead to death or serious injury.

• 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.

SECOND STAGE REGULATORS

A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.

The designation balanced and classic downstream are also distinguishing marks for second stages and again imply ultimate flow performance and stability in addition to reliability, simplicity and solid performance.ir-balanced valve technology.

S555 NITROX SECOND STAGE-ALL ROUNDER

Air balanced technology for high breathing performance, yet simple to operatefor fun and relaxation on every dive.  Initiates air flow effortlessly and instantly on demand.  Remarkably durable and reliable, compact and lightweight.

• Nitrox compatible configurations satisfy both advanced and recreational divers.  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 tank valves, which differ from the connections for compressed air tanks. This ensures utmost safety and no risk contaminating Nitrox with potentially hazardous hydrocarbons or residues.

• 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 & yellow color accents.

• WARNING: You must be fully trained and certified by a recognized diving training agency in order to dive with oxygen enriched air (Nitrox breathing mixtures). Diving with Nitrox without such certification could lead to death or serious injury

• Air-balanced valve technology. The air-balanced valve technology of SCUBAPRO’s second stages features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage. This allows reduced spring tension and decreases the inhalation resistance to the lowest possible level. The result is super smooth breathing in all conditions. The air-balanced valve technology is featured in the X and S-Series second stages. For best results they should be combined with balanced first stages, like the MK25 or MK17.

• Venturi Initiated Vacuum Assist (VIVA). Another SCUBAPRO patented feature, the VIVA is available on all SCUBAPRO second stages. VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver adjustable on all current SCUBAPRO second stages except the R295, since it is a second stage intentionally designed for diver training courses, rental facilities, and divers demanding ready to use equipment. A VIVA in MAX position gives powerful breathing support on every single breath; a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus.

• Orthodontic mouthpiece. SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.

• Precision moulded carbon fiber & technopolymer housing:  low friction, light weight, corrosion and cold water resistant for long life & sturdiness. 

• Sturdy high flow hose with kevlar lining for extra durability and flawless air delivery.

• 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 technician, before using them again with Nitrox.
