Aura Second Stage
Halcyon Aura second stage regulators provide a simple, compact design that makes breathing underwater feel natural. This high-quality second stage delivers air in a smooth, dependable fashion.
Halcyon’s Aura second stage comes with a single adjustment control and a pre-set inhalation effort that suits most common diving situations; this feature makes it a common selection as a backup regulator.
The Aura is an ideal regulator for divers who want a simple, ready-to-dive second stage; it is also a common choice for training systems and rental units.
Halcyon Aura is a classic downstream
Classic downstream valve style second stages have an impressive safety record and are commonly accepted as an extremely reliable design.
Part of their reliability results because the downstream valve opens in the same direction as the incoming airflow; a spring counteracts the force of the incoming air.
This design requires a small inhalation to overcome the spring tension and open the valve. The spring pressure is adjusted at the factory and allows easy breathing and consistent performance.
Air Control Vane
Air Control Vane (ACV) offers a second diver adjustment for the ability to fine-tune breathing. The ACV uses vacuum-assist technology to reduce the work of breathing and increase diver comfort.
This level of refinement is available on all Halcyon second stages. ACV in “dive” position gives powerful breathing support, while ACV in “Halcyon” position helps prevent free flows; this can be helpful on the surface, when diving in currents, while scootering, or when the Aura is used as a backup regulator.
Comfortable mouthpiece
Comfort mouthpiece is standard in every second stage to reduce jaw fatigue and mouth irritation. This long-lasting mouthpiece requires only a minimum effort to hold comfortably in place.
Combined with the freedom of head movement provided by Halcyon’s primary long hose, you will enjoy dives free from the jaw fatigue common with certain mouthpieces and/or poorly balanced hose routing.
- Compatible with 40% Nitrox (outside EU)
- Non-adjustable downstream valve
- Air Control Vane
Halcyon H-50D First Stage
The Halcyon H-50D first stage is a high-performance diaphragm design is fully sealed and purpose-built for harsh conditions like ice or environmentally contaminated environments. Diaphragm first stages are historically popular with cold water divers, and the Halcyon H-50D was engineered for extreme conditions.
Dive into extraordinary places with your H-50D, and be confident you have a rugged regulator to meet all your demands.
Environmentally sealed
The balanced, environmentally sealed diaphragm first stage performs better in cold water than any other diaphragm regulator while supplying consistent performance at varying tank pressures and depths; you will enjoy smooth, easy breathing throughout your dive.
The dry, balance chamber diaphragm design prevents water entry into the first stage mechanism and enhances a trouble-free operation; this is true even in the coldest conditions.
First stage ports
Two opposing high-pressure ports allow you to choose where to route your SPG and allow the use of accessories.
Four low-pressure ports allow you to customise your hose routing for comfort and convenience. The H-50D features four stationary low-pressure ports with high flow options, ensuring the best air delivery with up to 15% more air than other LP ports.
- Balanced, sealed diaphragm
- Dry balance chamber
- 2 x High-pressure Ports
- 4 x Low-pressure Ports (3/8)
- 300-bar DIN, compatible with 40% Nitrox
