High performance thanks to the V.A.D. system, in a simple and reliable second stage.
MR12 Axis
A new second stage made from reinforced technopolymer, featuring the integrated V.A.D. (Vortex Assisted Design) system, ensuring an exceptionally low breathing effort that is unprecedented for regulators of this class. Coverplate with “mesh grid” system to reduce the likelihood of free-flow even when swimming in strong currents. Exhaust tee with wide outlet ports, to minimize effort also during the exhalation phase. The MR12 first stage guarantees high performance and total reliability.
