Aqualung Regulator Helix Compact

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. Helps maintain oxygen compatibility, preserves internal lubrication, and keeps the inlet filter clean and dry, extending service life between services.

• PERMANENT DRY CHAMBER – Where there’s no moisture, there’s no ice. The Permanent Dry Chamber keeps internal parts clean and dry by isolating them from the outside environment, enhancing freeze resistance when diving in cold water.

• OVER-BALANCED MECHANISM (Auto-Balanced) – Overcompensates interstage pressure to reduce breathing effort. Provides effortless breathing from the beginning to the end of the dive, regardless of depth or tank pressure, resulting in superior performance at depth.

• BALANCED DIAPHRAGM – Provides superior and consistent performance.

• BLUE HIGH PRESSURE SEAT – The core of the first stage. Opens and closes with every breath, forming a perfect seal with durable materials suitable for all conditions and gases. Working pressure is automatically increased to counter higher breathing gas density.

• DUST CAP PROTECTION – Attached to the regulator body, protects the inlet fitting and ACD from impacts and damage, and seals 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 – Allows precise airflow control. In “MIN” position, valve assistance is minimized to avoid freeflow; in “MAX” position, assistance is maximized for lower inhalation effort. Ergonomic elastomer lever is easy to use even with gloves.

• CRACKING EFFORT ADJUSTMENT – Allows the diver to fine-tune 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 also reduces jaw fatigue during long dives.

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

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

• REUSABLE MOUTHPIECE CLIP – Enables quick and easy mouthpiece changes.

• BRAIDED HOSE – Provides flexibility, comfort, and excellent transportability.
