Description

MK2 EVO First Stage:
– Classic downstream piston design features a chrome-plated brass body with one high pressure and four low pressure ports.
– Patent pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance by an average of 50 percent.
– 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.
– Oversized piston provides better breathing performance by increasing airflow by 15 percent.
– Smaller chrome-plated brass body results in a lighter, more compact first stage.
– Stainless steel removable orifice allows for easier maintenance while extending regulator life.
– Meets new EN250-2014 standards for cold-water breathing performance.
– Weight: INT 230 – 24.9oz/706g; /DIN 300 – 17.1oz/485g.
– Airflow at 2900psi: 2600 l/min – 92 SCFM.
