Aqualung Regulator Leg3nd

First Stage

• Auto Closure Device (ACD) – Keeps the inlet closed to protect internal components 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 – With no moisture, there is no ice. The Permanent Dry Chamber isolates internal components from the external environment, keeping them clean and dry and increasing freeze resistance in cold water.
• De-Ice – Deep ribs create a large heat exchange surface to help prevent ice formation on the mechanism. The overmolded cap delays ice buildup on the external diaphragm.
• Over-Balanced Mechanism (Auto-Balanced) – Overcompensates interstage pressure to reduce breathing effort. Provides effortless breathing regardless of depth or tank pressure, from start to finish of the dive.
• Balanced Diaphragm – Ensures 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. Automatically increases working pressure to counter increased 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.
• Din and Yoke Screws – Ergonomically shaped bi-material screws with Soft Grip surface for better handling when installing or removing the first stage, even with cold hands.
• Channeled Yoke Screw – Prevents water retention.
• Hp/Mp Ports – Perfectly positioned for optimal 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%.
• Air Channel Deflector – Streamlined bi-material component evenly directs airflow through the second stage and reduces exhalation effort.
• Venturi Adjustment Switch – Allows precise airflow control. In “MIN” position, valve assistance is reduced to avoid freeflow; in “MAX”, assistance is maximized for lower inhalation effort. Ergonomic elastomer lever is easy to use even with gloves.
• Cracking Effort Adjustment – Enables fine tuning of breathing performance according to diving conditions.
• Pneumatically Balanced - Ensures smooth and easy breathing at all depths.
• Heat Exchanger – Prevents ice formation at the valve inlet.
• Overmolded Air Purge – Large purge area makes clearing the regulator easy and controlled.
• Overmolded Exhaust Cover – Soft-touch elastomer cover provides added protection.
• Black Coating – Durable stainless-steel parts feature a black Titadur® multi-layer coating for superior durability. Polymer parts are overmolded in black and anthracite tones for an exclusive look.
• Comfobite Mouthpiece  – Patented, comfortable 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 mouthpiece clamp allows quick, tool-free replacement, reducing plastic waste.
• Reusable Mouthpiece Clip – Enables fast and easy mouthpiece changes.
• Aqua Flex Hose – Lightweight, flexible hose with dual protectors.
