Atomic Z3 Scuba Diving Regulator
The Z3 brings Atomic’s balanced first-stage design to a regulator with a brass-based construction and protective finishes. Its second-stage adjustment and swivel hose connection provide practical comfort features for divers building a recreational setup around the Atomic platform.
Practical hose-routing choice
The Z3’s seven low-pressure ports are on a fixed cap. That gives you several connection positions while keeping the layout distinct from Atomic models with a rotating turret. Choose the port arrangement and optional sealing configuration to match the hoses and conditions you expect to use.
Features and benefits
- Balanced gas delivery. The balanced Jet Seat piston design helps manage the supply to the second stage as diving conditions change.
- Balanced second stage. The balanced valve helps maintain a consistent inhalation response.
- Mouthpiece comfort. The supplied dual-silicone comfort mouthpiece supports a comfortable hold at the second stage.
- Connection options. 2 HP ports and 7 on fixed cap LP ports support the stated gauge and hose configuration.
- Seven low-pressure ports. The fixed-cap first stage provides seven LP ports, giving you several hose-position choices without a rotating turret.
- Automatic Flow Control. AFC adjusts flow assistance with depth while the Rapid Adjustment Knob provides a manual handling adjustment.
- Protected second-stage components. The titanium and zirconium-coated components provide corrosion resistance in the Z3’s valve assembly.
- Comfort Swivel. The PVD-coated brass swivel helps the hose move at the second-stage connection, reducing pull at the mouth.
- Environmental sealing is optional. Select or confirm the sealed version if required; factory sealing is not assumed to be included in every Z3 configuration.
