First Stage

• Balanced diaphragm provides superior and consistent performance.
• Blue high-pressure seat: the core of the first stage; it opens and closes with every breath to form a durable seal. The working pressure is automatically elevated to compensate for increased breathing air density.
• Dust cap protection: attached to the regulator body to protect the inlet fitting and Auto Closure Device and to seal the first stage when off the tank.
• Ports: two HP ports (7/16") and four MP ports (3/8") arranged in a T-shape for streamlined hose positioning.
• Availability: DIN (4,350 psi / 300 bar max.) and Yoke (3,300 psi / 232 bar max.).

Second Stage

• Cover opening channels: front cover channels allow water to flow sideways over the diaphragm; wide radial openings help prevent freeflow in strong currents and reduce cracking effort by 20%.
• Venturi adjustment switch: adjustable air flow with MIN (minimal valve assistance to avoid freeflow) and MAX (maximum assistance for lower inhalation effort). The overmolded elastomer lever is ergonomically designed for use with gloves.
• ComfoBite mouthpiece: patented palate-bridge design reduces jaw fatigue and securely holds the second stage; made from hypoallergenic silicone.
• Interchangeable mouthpiece and reusable clip: detachable, tool-free mouthpiece clamp and removable clip allow quick changes and reduce plastic waste.
• Braided hose: provides flexibility, comfort, and excellent transportability.
