  • Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous  MK25 without compromising breathing performance. Key insulation system components are visible in blue.
  • New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
  • Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
  • Two opposing high pressure ports allow the first stage to be positioned either up or down.
  • Five high-flow low pressure ports on a swivel turret maximize hose routing options.
  • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
  • Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/570.
  • Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
  • Intermediate pressure (psi/bar): 133-142/9.2-9.8.

THE PISTON TECHNOLOGY

The general advantage of a piston-based 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 of 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 both warm and cold water environments. The SCUBAPRO MK25 first stage uses this technology.
