The Helix Compact Pro regulator combines a compact, travel-ready first stage with a comfortable, adjustable second stage designed for reliable breathing performance in varied diving conditions.

First stage

  • Travel-ready: Reduced size and weight for convenient travel.
  • Auto Closure Device (ACD): Protects the inlet when not connected to a cylinder valve, helping maintain oxygen compatibility, preserve lubrication, and keep the inlet filter clean and dry.
  • Permanent Dry Chamber: Isolates internal parts from the outside environment to reduce moisture and improve freeze resistance.
  • Over-balanced (Auto-Balanced) mechanism: Compensates interstage pressure to reduce breathing effort consistently at all depths and tank pressures.
  • Balanced diaphragm: Provides consistent performance.
  • Blue high pressure seat: Durable HP seat designed to seal reliably with all gases; working pressure is automatically elevated to counter increased breathing air density.
  • Dust cap protection: Attached dust cap protects the inlet fitting and ACD and seals the first stage when off the tank.
  • Ports: 2 HP ports (7/16") and 4 MP ports (3/8") oriented in a "T" shape for streamlined hose positioning.

Second stage

  • Cover opening channels: Wide radial openings direct water sideways over the diaphragm to reduce cracking effort and prevent freeflows in strong currents (reduces cracking effort by 20%).
  • Venturi adjustment switch: Overmolded lever with MIN and MAX positions to precisely control airflow and minimize freeflow or inhalation effort; usable with gloves.
  • Cracking effort adjustment: Fine-tune breathing performance for different diving conditions.
  • Pneumatically balanced: Smooth, easy breathing at all depths.
  • Heat exchanger: Helps prevent ice formation on the valve inlet.
  • Compact design: Suited for smaller faces and reduces jaw fatigue during long dives.
  • ComfoBite mouthpiece: Patented orthodontic silicone mouthpiece with palate bridge to reduce jaw fatigue and secure the second stage; hypoallergenic.
  • Interchangeable, reusable mouthpiece clip: Tool-free mouthpiece changes to reduce plastic waste.
  • Braided hose: Provides flexibility, comfort, and improved transportability.

Availability: DIN (4,350 psi / 300 bar max.) and YOKE (3,300 psi / 232 bar max.).
