Balanced first stage with Auto Closure Device, Permanent Dry Chamber and de-ice features for improved freeze resistance. Second stage offers Venturi adjustment, cracking effort tuning, ComfoBite mouthpiece and a flexible Aqua Flex hose for comfortable breathing and easy maintenance.


First stage

  • Auto Closure Device (ACD): Keeps the inlet closed when not connected to a cylinder valve to protect internal parts from debris and corrosive water, preserve internal lubrication, and maintain oxygen compatibility.
  • Permanent Dry Chamber: Isolates internal parts from the outside environment to keep them clean and dry, improving freeze resistance in cold-water diving.
  • De-Ice: Deep ribs increase heat exchange area and the overmolded cap delays ice formation on the external diaphragm.
  • Over-balanced mechanism: Also called auto-balanced; overcompensates interstage pressure to reduce breathing effort across depths and tank pressures.
  • Balanced diaphragm: Provides consistent performance.
  • Blue high-pressure seat: Durable sealing seat designed to operate reliably with all gases and compensate for increased air density.
  • Dust cap protection: Attached dust cap protects the inlet fitting and ACD from impacts and seals the first stage when off the tank.
  • DIN and yoke screws: Ergonomic bi-material "soft grip" screws for improved handling, especially with cold hands; channeled yoke screw prevents water retention.
  • HP/MP ports: 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: Front cover channels let water flow sideways over the diaphragm to reduce freeflows in strong currents and lower cracking effort by approximately 20%.
  • Air channel deflector: Streamlined bi-material component that evens airflow and reduces exhalation effort.
  • Venturi adjustment switch: Adjustable lever with overmolded elastomer allows control of airflow; "MIN" reduces valve assistance to help prevent freeflow, "MAX" increases assistance to lower inhalation effort.
  • Cracking effort adjustment: Allows fine tuning of breathing performance for different diving conditions.
  • Pneumatically balanced: Ensures smooth, easy breathing at all depths.
  • Heat exchanger: Helps prevent ice formation on the valve inlet.
  • Overmolded air purge: Wide, easy-to-control purge area for simple clearing of the second stage.
  • Overmolded exhaust cover: Elastomer "soft touch" cover for protection.
  • Durable finish: Stainless-steel parts receive a black Titadur multi-layer treatment; polymer parts are overmolded with black and anthracite tones.
  • ComfoBite mouthpiece: Patented palate-bridge design reduces jaw fatigue and secures the second stage; made from hypoallergenic silicone.
  • Interchangeable, reusable mouthpiece clip: Tool-free detachable mouthpiece clamp and reusable clip for quick changes and reduced plastic waste.
  • Aqua Flex hose: Flexible, lightweight hose with dual protectors.
