"ZEN" is a state of calm attentiveness where actions are guided by intuition rather than conscious effort." This is our ZEN of diving—you become one with the water, calm, attentive, breathing in and out intuitively without effort.
This regulator offers an ultra-lightweight and compact design to minimize jaw strain even during long dives.
Paired with our AC5, a piston-controlled first stage, it represents simplicity, robustness, and reliability. Maintenance is straightforward, fast, and cost-effective thanks to an ergonomic design that allows quick disassembly
and reassembly without specialized tools, reducing downtime and maintenance costs.
The AC5/ZEN features an optimized design for maximum airflow and an extra-large conical filter for improved filtration in both DIN and INT versions. Enlarged water passage slots ensure efficient rinsing, providing smooth, clean functionality and a true ZEN state of mind.
