Oceanic ZEO + FDXi Regulator Set – Premium Breathing Performance at Any Depth

Experience unmatched breathing comfort and reliability with the Oceanic ZEO + FDXi, a regulator system engineered for divers who demand the best in performance, control, and durability. Combining the advanced, pneumatically-balanced ZEO second stage with the ultra-efficient FDXi first stage, this system delivers smooth airflow, superb cold-water capability, and an ultra-comfortable breathing feel at every depth.

Engineered for Depth, Designed for Comfort

The ZEO second stage is built around a chrome-plated marine brass valve, offering enhanced cold-water performance and exceptional durability. This all-metal valve naturally condenses water vapor from exhaled breath, helping reduce dry mouth—a common problem during long dives. The result? A smoother, more comfortable breathing experience in any environment.

With Dynamic Adjustment Technology, divers get a consistent inhalation effort throughout the dive, while the diver-adjustable inhalation knob allows instant fine-tuning of airflow. Paired with the Adjustable Venturi Switch (A.V.S.), the ZEO ensures easy breathing during descent and controlled airflow on the surface.

First Stage Excellence – FDXi

The FDXi features an efficient in-line diaphragm design that improves airflow and reduces weight compared to traditional L-shaped first stages. Cold-forged for strength and durability, it is fully environmentally sealed, making it highly reliable for cold-water and contaminated-water diving.

With 4 LP ports and 2 HP ports, hose routing is clean, streamlined, and perfect for both recreational and technical setups.

Comfort & Ergonomics

For all-day use, the ZEO comes with an inline ball swivel, significantly reducing jaw fatigue. The orthodontic mouthpiece adds extra comfort, making long dives more enjoyable and reducing strain on the diver.
