Atomic Aquatics Z3 Sealed Swivel Regulator by Atomic

The Z3 is a is a balanced flow-thru piston design using Atomics jet seat high flow stainless steel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic employs a conical seat and blunt end piston. Atomics' 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. The Z3 is also freeze protected with a factory sealed first stage. The regulator is Nitrox ready for mixtures Up to 40% out-of-the-box. The first-Stage has 2 high-pressure (HP) 7/16" and 7 low-pressure (LP) 3/8" ports.

• 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.
• The Z Series second stage lever, orifice and spring are Titanium.
