MK25 EVO First Stage<br />
• Air balanced flow-through piston in a chrome-plated<br />
brass body provides constant and effortless airflow<br />
unaffected by depth, tank pressure, or breathing rate.<br />
• Patented XTIS (Extended thermal Insulating system)<br />
fully insulates the inner mechanism from the environment,<br />
improving cold-water resistance by 30% and<br />
delaying ice formation in extreme cold-water conditions<br />
without compromising breathing performance.<br />
Key insulation system components are visible in blue.<br />
• Anti-freeze protection radically increases breathing<br />
reliability when diving in the most extreme water temperatures.<br />
• Two opposing high pressure ports allow the first stage<br />
to be positioned either up or down.<br />
• Five high-flow and one axial super high-flow low pressure<br />
ports on a swivel turret maximize hose routing<br />
options.<br />
• External intermediate pressure adjustment enables<br />
technicians to fine-tune performance quickly and<br />
easily.<br />
• Weight (oz/g): INT 232, 27.9/790; DIN 300, 20.1/572.<br />
• Airflow at 2900psi/200bar: (l/min/SCFM):<br />
>8500/301.<br />
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.<br />
MK21 First Stage<br />
• Air-balanced flow-through piston provides constant<br />
and effortless airflow unaffected by depth, tank pressure,<br />
or breathing rate.<br />
• Polished chrome-plated marine grade brass body<br />
is close to 20% smaller than the MK25, making it an<br />
easy travel companion.<br />
• Unique thermal exchange design with external fins<br />
optimizes freezing resistance.<br />
• Two high pressure ports, one on each side of the<br />
body, allow the first stage to be positioned either up<br />
or down.<br />
• Standard “smart” hose routing cap offers four low<br />
pressure ports angled for more convenient hose<br />
routing (+/- 20º).<br />
• Optional hose routing cap increases routing configurations<br />
with four angled low pressure ports (0°/30°)<br />
plus a fifth centralized high-flow low pressure port,<br />
ideal for technical diving.<br />
• Redesigned yoke allows for easier mounting on a cylinder,<br />
and a redesigned cap protects internal components<br />
from water intrusion after the dive.<br />
• Weight (oz/g): INT 232, 27.5/780; DIN 300, 20.1/570.<br />
• Airflow at 2900psi/200bar: (l/min/SCFM):<br />
>7500/265.<br />
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.<br />
