The Atomic Aquatics B2 Regulator combines premium materials, effortless breathing performance, and rugged durability to create one of the most respected regulators in recreational and professional diving. Designed with technology derived from Atomic’s flagship models, the B2 delivers elite performance while remaining accessible to a wide range of divers.

At the heart of the system is a balanced high-flow piston first stage constructed from chrome-plated brass and 316 stainless steel. This design ensures consistent airflow and dependable performance at any depth, while optional environmental sealing helps protect internal components from sand, silt, and contaminants. The all-titanium second stage provides exceptional corrosion resistance and extremely smooth breathing thanks to its pneumatically balanced poppet design. Atomic’s patented Automatic Flow Control (AFC) automatically adjusts the Venturi effect as depth changes, allowing divers to breathe naturally without constant manual adjustments.

For added comfort, the B2 features Atomic’s patented Comfort Swivel Hose, which allows a 30° range of movement to reduce jaw fatigue and hose pulling during a dive. The lightweight system also incorporates a high-flow case and elliptical exhaust valve to minimize breathing resistance even at depth.

Built for longevity, the B2 regulator is Nitrox compatible up to 40% out of the box, as well as offering a 2 year or 300 dive service interval.
