Atomic Z3 Scuba Diving Regulator

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

• Protective material finishes. The chrome-plated brass first stage is paired with a zirconium-coated brass second-stage valve body and titanium components in key parts of the mechanism.
• Balanced Jet Seat piston. The balanced first-stage mechanism regulates the gas supply as cylinder pressure falls, supporting a consistent breathing response.
• Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
• Automatic Flow Control. AFC changes the Venturi assistance as depth changes, reducing the need for manual flow adjustment. The Rapid Adjustment Knob provides additional control for handling and specific diving situations.
• Comfort Swivel. The second-stage hose connection moves with your head, helping reduce hose pull and strain at the mouthpiece.
• Seat-saving design. When the regulator is depressurised, the dynamic orifice lifts away from the low-pressure seat. This reduces prolonged loading on the seat during storage.
• Fixed-port hose layout. The first stage offers several low-pressure connection positions, allowing hoses to be arranged around the equipment without a rotating turret.
• Optional environmental sealing. Environmental sealing is available for this platform. Confirm the supplied configuration if protection against silt and sand is part of your equipment requirements.

Setup and compatibility

Care, rinsing and storage

After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.

For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.

Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.

Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised Atomic Aquatics technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
