The Atomic Z3 Regulator offers a unique combination of performance, ergonomics, features and materials. All in Atomics’ most cost-efficient regulator system without compromising performance or durability. Pair it with Atomic Z2 Octopus.

Z3 Zirconium Regulator

Divers on a budget can experience virtually the same easy, natural breathing and corrosion resistance as the entire Atomic regulator line. The performance is delivered from patented Atomic exclusives, including the Jet Seat piston and AFC. The economy is achieved from the exclusive use of Zirconium-plated Brass materials.

Automatic Flow Control

You shouldn’t have to think about breathing when you dive. The exclusive Atomic AFC helps you breathe naturally at any depth without thinking about making adjustments.

The Atomic AFC eliminates the manual adjustment normally needed to regulate Venturi effect as you dive deeper. No dials to turn or buttons to push. A Rapid Adjustment Knob is included for special situations like surf entry or octo use.

Comfort Swivel

When you turn your head to look at something interesting, you’ll look great doing it with the uniquely all-black Atomic Comfort Swivel. This exclusive Atomic design allows 30° rotational movement without hose pulling, binding or kinking. The Z3 version is precision-machined Brass with black PVD coating.

Jet Seat Piston

The Atomic Jet Seat system has no sharp edges that can damage the seat over time. Instead, Atomic employs a conical seat and blunt-end piston.

Atomic valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.
