Atomic Z3 Swivel Diving Regulator

Atomic Z3 Swivel Diving Regulator

The Z3 offers the best cost-benefit ratio in the Atomic line. Its combination of performance, ergonomics, and materials is unmatched by more expensive competitors. Built on the B1/T1 platform, it shares the same breathing performance and patented features. The Z3 includes all the features of the Z2 plus more.

The Z3 is a balanced flow-through piston design using the Atomic Jet Seat high-flow stainless steel piston. The exclusive high-pressure piston sealing system is self-lubricating for low friction and low maintenance. The Atomic Jet Seat system has no sharp edges that could damage the seat over time, unlike most competitors’ first stages. Instead, Atomic uses a tapered seat and a blunt piston tip. Atomic valve seats are precision-machined from an extremely strong aerospace-grade material. This design combination results in the most reliable seat system in the industry and allows the seat to last 2 years or 300 dives without service. Diving performance is superior even at low tank pressure.

The Z3 is also freeze-protected with a factory-sealed first stage that prevents contaminants such as silt and sand from entering the valve mechanism. The regulator is Nitrox-ready for mixes up to 40% out of the box. The first stage has 2 high-pressure (HP) ports 7/16" and 7 low-pressure (LP) ports 3/8".

The Z-series second stage is a balanced linear flow design for extremely easy breathing at all depths and diving conditions. It is built to last with a zirconium-plated brass demand valve body, titanium lever, and sealing orifice. The diaphragm is made of high-quality silicone rubber. This pneumatically balanced second stage features Atomic’s patented dynamic seat-saving orifice, which—unlike most second-stage orifices—is a floating valve design that reduces wear on the second-stage seat when the regulator is not pressurized, extending the life of this important seal.

The Z-series second stage is equipped with Atomic’s patented Automatic Flow Control (AFC), which automatically controls airflow and the Venturi effect for optimal breathing resistance at all depths. The second stage features a soft quick-adjust knob for rare special situations. If you have ever experienced second-stage “pulling” when turning your head underwater, those days are gone with the fully rotating Atomic titanium PVD-coated swivel. One of the most admired features is the patented Comfort Swivel that allows 30° rotation without binding or twisting.

The Z3 also features a new high-flow second-stage case and Magnum lever design that significantly reduces breathing effort at any depth, from shallow water to beyond limits. A dual-material purge cover allows full front-face purging, and a double silicone mouthpiece with comfortable bite tabs. The Z3 features a metal-accented front cover ring. It comes with a 32 in (81.3 cm) 3/8" low-pressure hose. Weight: 2.6 lbs (1,151 g).
