The Atomic Aquatics Z3 Regulator delivers Atomic Aquatics’ signature breathing performance in a durable, travel-friendly design. Built with zirconium-plated brass and stainless-steel components, the Z3 offers excellent corrosion resistance and reliability while remaining one of the most affordable regulators in the Atomic lineup.

At the core of the Z3 is Atomic’s balanced Jet Seat high-flow piston first stage, engineered to provide smooth, consistent airflow regardless of depth or tank pressure. The regulator can also be ordered with a factory sealed first stage that protects internal components from sand, silt, and contaminants, ideal for divers who frequently dive in demanding environments. The pneumatically balanced second stage features precision-machined brass with zirconium plating and titanium internal components, delivering effortless breathing and long-term durability. Atomic’s patented Automatic Flow Control (AFC) automatically optimizes the Venturi effect as depth changes, reducing the need for manual adjustments while maintaining stable airflow throughout the dive. For added comfort, the regulator includes the patented Atomic Comfort Swivel hose, allowing up to 30° of rotation to prevent hose binding and reduce jaw fatigue during long dives. A soft rapid-adjustment knob allows divers to fine-tune breathing resistance in special situations such as surf entries or when using the regulator as an octopus.

Nitrox-ready up to 40% oxygen and has a service interval of 2 years/ 300 dives, the Z3 provides premium performance and reliability for both new and experienced divers.
