The Aqualung Helix DIN Regulator is a balanced diaphragm first and second stage regulator designed for divers seeking reliable performance at a mid-range price point. Manufactured in France, it embodies the core DNA of Aqualung regulators.
- Balanced Diaphragm First Stage: Ensures consistent and superior performance across varying depths and tank pressures.
- T-Shaped Body Design: Optimizes hose positioning, reducing exhalation effort and keeping bubbles out of the diver's field of view.
- Ergonomic Venturi Lever: Allows precise adjustments to prevent unwanted free-flow at the surface and provides a performance boost at depth, even when wearing gloves.
- Nitrox Compatibility: Ready for use with up to 40% oxygen (EAN 40) right out of the box.
- Maintenance Interval: Recommended service every 2 years.
