Atomic Z3 Regulator

Atomic Aquatics Z3 Regulator

Premium Atomic breathing performance in the brand's most compact and affordable regulator.

The Z3 gives you the smooth, natural breathing Atomic is known for at a mid-range price. It uses the same patented technology found higher in the line, wrapped in sleek all-black styling. At just 2.6 lbs (yoke version), it's light enough to be your go-anywhere travel regulator.

First Stage

• Balanced Jet Seat high-flow piston: Atomic's exclusive design uses a conical seat and blunt-end piston, so there are no sharp edges to wear the seat down. It delivers strong performance even at low tank pressure.
• Rugged build: Chrome-plated brass and 316 stainless steel.
• Nitrox ready: Approved for non-dedicated use with mixes up to 40%.
• Plenty of ports: 7 LP and 2 HP ports for flexible hose routing.
• Sealed option: A factory-sealed version keeps out silt and sand and adds cold-water protection.

Second Stage

• Automatic Flow Control (AFC): Atomic's patented system adjusts the venturi effect for you as you descend, so breathing feels consistent at any depth without constant knob-twiddling.
• Titanium Seat Saving Dynamic Orifice: Lifts the valve off its seat when not in use. This protects the regulator in storage and keeps its factory tuning crisp.
• Pneumatically balanced poppet: Paired with a high-flow case and lever for easy inhalation at every depth and tank pressure.
• Corrosion-resistant materials: Zirconium-plated brass with titanium components.
• Comfort Swivel: The black PVD-coated brass swivel gives 30° of rotation, so there's no hose pull or kinking when you turn your head.
• Rapid Adjustment Knob: Lets you detune manually for surf entries or octopus use.
• Full-face purge: Large purge surface for easy clearing.

Low Maintenance, Long Life
The Z3 has a 2-year / 300-dive service interval, where most regulators need annual service. It's backed by Atomic's limited lifetime warranty.

Available in: Yoke (232 bar) and DIN (300 bar). An optional color kit is available.
