A perfect complement to any of our regulator systems, the Z2 will make the perfect addition to any divers set up. All Zirconium plated brass and titanium metal components, making this second stage a real workhorse.
Most manufacturers produce just an economy and a performance octopus model. Yet, even their high-end octopus cannot come close to matching the performance of the Atomic safe seconds. Each Atomic Octopus is designed, and precision built to perform as perfectly as its primary model counterpart. So, when you need it, you know exactly what to expect.
The Z2 Safe Second Stage features critical metal components of the demand valve that are made of titanium or 316-stainless-steel and is completely corrosion proof. The demand valve housing is machined from brass and plated with an exotic zirconium plating that exponentially outlasts conventional chrome plating.
The Atomic Z2 Octopus diaphragm is made from high quality silicone rubber. This pneumatically balanced poppet second stage has Atomics patented seat saving dynamic orifice which unlike most second stage orifices is a floating valve design which reduces wear on the second stage poppet seat when the regulator is not pressurized adding life to this important seal.
The Z2 Second-Stage Regulator is equipped with Atomics patented Automatic Flow Control (AFC). This unique diaphragm activated vain automatically controls the flow and Venturi effect of the second stage for optimum breathing resistance at all depths. The second stage does have a rapid adjustment knob for manual second stage de-tuning in rare special situations. The Z2 Octopus has a bright yellow front cover for easy identification in an out-of-air-emergency and a 36" (91.4 cm) 3/8" threaded low-pressure (LP) hose. The regulator is also equipped with a dual silicone comfort fit mouthpiece with tear resistant bite tabs and weighs 12.3 oz. (349 g) with the hose.
