Atomic Aquatics Z3 has all the features of the Z2 and then some. 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 that also prevents contamination such as silt and sand from entering the valve mechanism. 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.

A dual material second stage cover enables entire front to be used for purging and a dual silicone comfort fit mouthpiece with tear resistant bite tabs. The Z3 has a metal accented front cover ring. The regulator comes equipped with a 3/8" threaded 32" (81.3 cm) low-pressure hose. The regulator weighs 2.6 lbs. (1,151 g) and comes with an owner's manual.
