MK25 EVO: an air-balanced piston for instant air on demand
The MK25 EVO first stage uses an air-balanced flow-through piston in a chrome-plated brass body. It delivers air instantly on demand, and the airflow stays constant and effortless whatever your depth, tank pressure or breathing rate. Two opposing HP ports let you mount it facing up or down, and five LP ports on a swivel turret (four high-flow, one axial super high-flow) give you more ways to route your hoses.
