ATX Stage 3 – Dive Regulator DIN + Octopus

The Apeks ATX Stage 3 Regulator is a reliable, high-performance diving regulator designed to deliver smooth and effortless breathing at all depths. Based on the proven ATX range, it features a fully balanced first and second stage with cold-water capability, making it suitable for diving in all water temperatures, including below 10°C / 50°F.

First Stage Features

• DS4 Over-Balanced Diaphragm Design: The over-balanced design allows intermediate pressure to increase faster than ambient pressure during descent, ensuring excellent breathing performance at greater depths.
• Port Configuration: Equipped with 1 high-pressure (HP) port and 4 medium-pressure (MP) ports.
• Environmental Dry System: Prevents water from entering the main spring chamber, reducing the risk of ice buildup and protecting against silt and contamination.
• Connection Options: Available in DIN and Yoke configurations.

Second Stage Features

• Pneumatically Balanced Design: Provides smooth, easy, and comfortable breathing.
• Large Purge Button: Easy to operate, even when wearing thick diving gloves.
• Integrated Venturi Control: Enhances breathing performance at depth while helping prevent unwanted freeflow at the surface.
• Efficient Exhaust Valve: Improves overall breathing performance.
• Comfo-bite™ Mouthpiece: Designed to minimize jaw fatigue and provide a comfortable fit.
• Patented Heat Exchanger: Surrounds the valve mechanism, dissipating cold caused by gas expansion while absorbing warmth from the surrounding water.
• Compact Exhaust Tee: Features an integrated, compact exhaust tee for a streamlined design.
