MK25 / S555 Regulator Set
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.
MK25 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.
MK25 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.
