The Aqualung LEG3ND PARTNER DIN Scuba Diving Regulator is a high-performance, third-generation regulator designed for demanding divers seeking reliability and comfort. Tailored for assistance and rescue operations, it features enhanced visibility and the LEG3ND-AIRE breathing comfort system.
- First Stage:
- Auto Closure Device (ACD): Automatically shuts the inlet when not connected to a cylinder valve, protecting internal components from contaminants and corrosive water. This feature helps maintain internal lubrication and keeps the inlet filter clean and dry.
- Permanent Dry Chamber: Isolates internal parts from the external environment, preventing moisture and ice formation, which is particularly beneficial in cold water conditions.
- Over-Balanced Mechanism: Automatically increases the working pressure to counteract the increased density of inhaled air at greater depths, ensuring optimal breathing effort throughout the dive.
- Ergonomic Design: DIN screws and bracket feature a bi-material "Soft Grip" surface, providing better grip during assembly and disassembly, especially with cold hands.
- ACD Dust Cap: Attached to the regulator body, it protects the inlet connection and ACD system from impacts and damage.
- Port Configuration: Two High-Pressure (HP) and four Medium-Pressure (MP) ports are strategically positioned for optimal hose routing.
- Second Stage:
- Pneumatically Balanced: Ensures smooth and effortless breathing at all depths.
- Heat Exchanger: Surrounds the valve mechanism to dissipate cold caused by gas expansion, drawing heat from the ambient water to prevent ice formation.
- Venturi Adjustment Lever: Prevents unwanted free flow at the surface while enhancing performance at depth.
- ComfoBite Mouthpiece: A patented design featuring a unique palate bridge that reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone, it is both soft and sturdy.
- Overmolded Air Purge: A wide surface area makes purging the regulator easier, and the depth controller optimizes airflow with minimal effort.
- Overmolded Exhaust Cover: Made of elastomer with a "soft touch" effect, it provides protection and comfort.
- Aqua Flex Hose: Flexible and lightweight with dual protectors, reducing drag and enhancing maneuverability.
