Technical Information

MK2 EVO First Stage:

• Classic downstream piston design features a chrome-plated brass body with one high pressure and four low pressure ports.
• Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance by an average of 50 percent over its predecessor without compromising breathing performance.
• Additional internal technical improvements include a new spring insulating bushing and coating, a new insulating piston bushing, a new insulating sleeve and a new antifreeze cap, all of which contribute to the increase in freezing resistance. Key insulation system components are visible in blue.
• Chrome-plated brass body is 3.5mm smaller than its predecessor but houses an oversized piston by 1.6mm that provides better breat ing performance by increasing airflow by 15 percent.
• Stainless steel removable orifice allows for easier maintenance while extending regulator life.
• Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
• Meets new EN250-2014 standards for cold-water breathing performance.
• Weight: INT 232 - 23.6oz/670g; /DIN 300 -15.9oz/450g.
• Airflow at 2900psi/200bar (l/m/SCFM): 3000/106.
• Intermediate pressure (psi/bar): 138-145/9.5-10.
