Designed as a value for money regulator in the Atomic range, the Z3 is recognised by many as the best bang for buck regulator on the market.

The Z3 first stage is built from zirconium plated brass which gives excellent corrosion resistance.

Due to this corrosive resistance and the hardwearing material, Atomic offer the industry’s leading recommended service interval of 2 Years or 200 Dives, this regulator is built to go year after year without a drop in performance.

Internally the Z3 utilises a high flow piston which efficiently regulates the tank pressure exactly dive after dive.

The low-pressure ports are housed on the main body which makes for a compact streamlined first stage.

The Z3 second stage houses a fully balanced valve and lever that has a super smooth air delivery regardless of depth, the same high-quality valve body that is found in the world leading T3 regulator.

The second stage has a fantastic 360-degree swivel which ensures the regulator is always in the right place, reducing jaw fatigue and making your dive more comfortable for longer.

Like all Atomic second stages it also features the patented “AFC” Automatic Flow Control that eliminates the need for an external pre-dive switch and automatically adjusts with depth to ensure your regulator doesn’t free flow.

Another unique Atomic second stage patent is the “seat saving orifice” that allows for the seat to pull away from the sealing knife edge when not in use, significantly reducing the wear on this important component and therefore increasing longevity of the regulator’s performance.

The Z3 is available in both yoke and DIN options and is ready for 40% Nitrox use.

The “Z” designation is represented by the use of Zirconium as plating material for the precision machined Brass valve body. Atomic developed a Zirconium over Chrome over Brass plating process to deliver corrosion-resistance 3-4 times that of conventional chrome plating.


Designing affordability doesn’t mean using shortcuts.
The Z Series is our most compact and economical regulator system. But its rare combination of performance, ergonomics and materials is unmatched by competitors at any price.
