Description:Patent pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance by an average of 50 percent.
The new MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort -- regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the current MK2.
The MK2 EVO is the only downstream piston style first stage in its price range to offer systems and internal components specifically designed to resist freezing in extreme cold-water conditions. When teamed with the R195, this reg system is reliable, easy to maintain and even easier to use.
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.
Available in INT or DIN configurations.
Classic downstream valve comes with VIVA switch to control free flows at the surface.
Metal valve housing is built rugged and increases overall reliability.
Super-flow hose features oversized bore to increase airflow.
