Aqualung Pack Helix Compact Pro + Octo

First Stage

• TRAVEL-READY: Reduced size and weight make the Helix Compact Pro the ideal choice for travelers.

• AUTO CLOSURE DEVICE (ACD): Keeps the inlet shut to protect internal parts from debris and corrosive water when not connected to a cylinder valve. Maintains oxygen compatibility, preserves internal lubrication, and keeps the inlet filter clean and dry, extending service life.

• PERMANENT DRY CHAMBER: Where there’s no moisture, there’s no ice. Isolates internal components from the external environment, enhancing freeze resistance in cold-water diving.

• OVER-BALANCED MECHANISM (Auto-Balanced): Overcompensates interstage pressure to reduce breathing effort, delivering effortless breathing regardless of depth or tank pressure. Ensures superior performance at depth.

• BALANCED DIAPHRAGM: Provides superior and consistent performance.

• BLUE HIGH PRESSURE SEAT: Core of the first stage. Opens and closes with every breath, forming a perfect seal with durable materials suitable for all conditions and gases. Automatically increases working pressure to counter higher gas density.

• DUST CAP PROTECTION: Attached to the regulator body to protect the inlet fitting and ACD from impacts and damage, sealing the first stage when off the tank.

• HP / MP PORTS: 2 HP ports (7/16”) and 4 MP ports (3/8”) arranged in a “T” shape for streamlined hose routing.

• AVAILABILITY: DIN (4,350 psi / 300 bar max.) and YOKE (3,300 psi / 232 bar max.).

Second Stage

• COVER OPENING CHANNELS: Allow water to flow sideways over the diaphragm. Wide radial openings prevent freeflows in strong currents and reduce cracking effort by 20%.

• VENTURI ADJUSTMENT SWITCH: Enables precise airflow control. “MIN” position reduces valve assistance to avoid freeflow; “MAX” position maximizes assistance for lower inhalation effort. Ergonomic elastomer lever is easy to operate even with gloves.

• CRACKING EFFORT ADJUSTMENT: Allows fine tuning of breathing performance according to different diving conditions.

• PNEUMATICALLY BALANCED: Ensures smooth and easy breathing at all depths.

• HEAT EXCHANGER: Prevents ice formation at the valve inlet.

• COMPACT DESIGN: Ideal for smaller faces, such as women and younger divers, ensuring it does not obstruct the underwater field of vision. Lightweight design reduces jaw fatigue during long dives.

• COMFOBITE MOUTHPIECE: Patented mouthpiece with a unique palate bridge that reduces jaw fatigue and keeps the second stage securely in place. Made from hypoallergenic silicone.

• INTERCHANGEABLE MOUTHPIECE: Detachable, reusable clamp allows quick, tool-free replacement, reducing plastic waste.

• REUSABLE MOUTHPIECE CLIP: Enables fast and easy mouthpiece changes.

• BRAIDED HOSE: Flexible, comfortable, and highly transportable.
