High-Performance Design with Flexible Hose Routing
This pneumatically balanced diaphragm first stage is built for divers who need both reliability and versatility underwater. It uses a 360 Degree rotating turret with 5 low-pressure ports allowing hose routing that adapts to any configuration. All LP ports are equipped with Dynamic Flow Control (DFC), delivering high and consistent airflow at every depth. 2 high-pressure ports with Optimized Port Design (O.P.D.) are angled on opposite sides for ideal transmitter and gauge placement.
Durable Build with Dry-Seal Protection
Constructed from chrome-plated brass and finished with a pearl-effect coating, the regulator body offers excellent resistance to abrasion and corrosion. The Auto-Sealing Technology (AST) activates automatically when airflow begins, creating a dry-seal barrier that keeps water out of the first stage. This system operates without mechanical parts, improving reliability in harsh diving conditions such as cold water or silty environments.
Versatile Configuration for Demanding Dive Profiles
The turret can be positioned facing upward or downward, giving divers full control over gear layout. The INT connection offers compatibility with standard tank valves, making it suitable for both recreational and advanced applications. Whether diving with multiple second stages or a transmitter setup, the balanced first stage regulator is engineered to support efficient gas delivery and customized hose routing on any dive.
