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.

- Experience smooth, natural breathing and signature Atomic Aquatics technology at an accessible price with the Atomic Aquatics Z3 Scuba Diving Regulator. Combining a balanced high-flow first stage, pneumatically balanced second stage and exclusive Automatic Flow Control, the Z3 delivers dependable airflow and excellent comfort throughout every dive.
- The Z3 features distinctive all-black styling, a corrosion-resistant Zirconium-plated second-stage valve body and a patented Comfort Swivel that allows the regulator hose to move naturally as you turn your head. Available with a Yoke or 300-bar DIN connection, it is a versatile regulator for recreational diving, travel and everyday use.
- The Z3 second stage uses a pneumatically balanced poppet with a high-flow case and lever. This design helps maintain consistent breathing effort as depth and cylinder pressure change.
- Whether you are beginning a dive with a full cylinder or returning to the surface at lower pressure, the Z3 is engineered to provide smooth, predictable airflow.
- The Atomic Aquatics Comfort Swivel provides approximately 30 degrees of movement at the second-stage hose connection.
- The Z3 Comfort Swivel is precision-machined from brass and protected by a black PVD coating for enhanced corrosion resistance and a streamlined all-black appearance.
- The patented Titanium Seat Saving Dynamic Orifice retracts when the regulator is not pressurised. This prevents the sealing edge from continuously pressing against the low-pressure seat during storage.
- Protecting the seat from prolonged pressure helps
- The Z3 first stage provides seven low-pressure ports on a compact fixed cap—more than many conventional recreational regulators.
- Additional low-pressure accessories
- Two fixed high-pressure ports provide mounting options for a pressure gauge, transmitter or instrument console.
- The dual-silicone comfort mouthpiece combines a soft, comfortable bite with strong, tear-resistant tabs. It helps maintain a secure fit without requiring excessive jaw pressure.
- Balanced Jet Seat high-flow piston provides stable airflow
- Pneumatically balanced second stage delivers smooth breathing at varying depths
- Automatic Flow Control manages the venturi effect throughout the dive
- Patented Comfort Swivel offers approximately 30 degrees of movement

- Nitrox-ready for non-dedicated mixtures containing up to 40% oxygen
- Available with Yoke or 300-bar DIN connection
- The Z3 is an excellent choice for divers who want Atomic Aquatics breathing technology, excellent comfort and flexible equipment configuration without moving into the brand’s premium titanium regulator range.
- Its balanced airflow, Automatic Flow Control, Comfort Swivel and protective Dynamic Orifice make it a capable regulator for new divers, experienced recreational divers and frequent travellers. With seven low-pressure ports and both Yoke and DIN options available, it can be configured for a wide variety of diving setups.
Balanced Jet Seat High-Flow First Stage

- The Z3 first stage is manufactured from chrome-plated brass with 316 stainless-steel components, providing dependable durability for regular saltwater and freshwater diving.
