The Atomic Z2 Regulator features a completely new second stage housing that includes a re-designed, hi-flow case. The attractive two-tone design is available in gray or blue. But while a visually-appealing product, the Z2’s strength comes from its performance and interior design.

The “Z” designation represents 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 to 4 times that of conventional chrome plating.

Divers will appreciate how easy the Z2 breathes thanks to Atomic innovations like the patented Automatic Flow Control (AFC), seat-saving orifice and “Jet Seat” first stage piston design.
