Scubapro Set Mk25AF / S555 / R395

THE S-SERIES

These systems cater to passionate divers who demand flawless performance and total relaxation. The SCUBAPRO S-Series regulators feature air-balanced valve technology providing ultra-high airflow that remains exceptionally stable under all breathing conditions.

MK25AF / S555 REGULATOR SYSTEM

A powerful all-rounder.

Our top performing balanced piston first stage, paired with our S555 air balanced second stage, is the ideal choice for a diver wanting a high performance yet simple to operate system, remarkably durable and reliable.

S555 is a compact and lightweight air balanced second stage marrying advanced breathing performance with a captivating design. It increases fun and relaxation on every dive because it initiates air flow effortlessly and instantly on demand, independent of the tank pressure. As with all of the X and S series second stages, S555 features a super-flow hose for smooth air delivery.

MK25AF FIRST STAGE
SCUBAPRO has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 is a balanced piston first stage, our absolute top performer. It is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air. This means instant airflow at any tank pressure and water temperature for a real carefree dive.

THE PISTON TECHNOLOGY. The general advantage of a piston first stage lies in its reliability and reduced maintenance requirements, due to an effective but simpler mechanism with less moving parts. More importantly, no other design can reach the high air delivery rate of a balanced piston controlled first stage.

· Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra fast breathing response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold water environments.

· Two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck.

· Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports.

· DIN/INT first stage configurations- To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 232bar INT version as well as 300bar DIN versions.

· Externally adjustable intermediate pressure- Allows authorized SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage.

· Chrome plated brass body- machined marine grade, for excellent resistance to corrosion and long lasting robustness.

· Cold Water Diving With SCUBAPRO- Diving conditions can be drastically different, including extreme cold water and ambient air temperatures, posing the possibility of a regulator "freezing". Therefore, resistance to freezing is imperative for the diver. All SCUBAPRO regulator systems are CE approved for 300bar cold water diving. Some models go even beyond this super stringent qualification and have successfully been tested in extreme cold diving conditions at less than 2°C. As a specific anti-freezing measure, SCUBAPRO engineers have designed special anti-freeze components and features for the MK25 first stages for optimal cold water diving. The ribs act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop. For cold water diving, SCUBAPRO-s second stages feature precision molded carbon fiber and technopolymer valve housing and components. They even exceed the CE cold water norm. In addition, these components contribute to their lightweight features and corrosion resistance.

S555 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 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.

R395 SECOND STAGE REGULATOR

- Classic downstream valve. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming air flow. To close the valve and stop the air flow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.

- Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane. Fixed in the pre-tuned ideal position for safe and uncomplicated use.

- Extremely lightweight and compact. Comfortable for all divers, including junior divers newly initiated in the sport.

- 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.

The Set includes: 1. Stage MK25AF, DIN, Scubaprohoses, S555 2. Stage, Oktopus R395, and Scubapro Console TWIN Compact.
