MAYA — Unbalanced Piston First Stage
Compact Design. Proven Reliability.

The MAYA is a compact unbalanced piston first stage engineered to deliver dependable performance in an exceptionally small package. Fully compliant with EN250A requirements, it combines the simplicity and reliability of a piston design with a footprint significantly smaller than traditional first stages.

A stable intermediate pressure of 9–9.5 bar (130–135 psi) ensures smooth and consistent gas delivery throughout the dive, while the straightforward piston architecture offers durability, ease of maintenance, and long-term reliability.

Manufactured from marine-grade brass and protected by a military-spec chrome finish, the MAYA is built to withstand the harsh marine environment. For divers seeking enhanced durability and a distinctive appearance, an optional Zirconia PVD ceramic coating provides exceptional resistance to wear, scratching, and corrosion.

Safety remains central to the design. The fail-safe pressure-loss system is engineered to maintain a predictable response in the event of a malfunction, providing an additional layer of confidence in demanding diving conditions.

Available in both 300 bar DIN and 232 bar Yoke configurations, the MAYA features four low-pressure ports (3/8″) and one high-pressure port (7/16″), allowing flexible hose routing for a wide range of equipment setups.
