Outstanding Breathing Performance Thanks to DS4 First Stage

The Apeks DS4 first stage impresses with its over-balanced, diaphragm-controlled design. This means the air delivery remains constant regardless of depth or cylinder pressure. Even on demanding dives in greater depths or with low cylinder pressure, you benefit from a consistently comfortable breathing resistance. Thanks to its fully sealed construction with dry chamber, the stage is not only cold water compatible but also optimally protected against contamination. The DS4 provides one high-pressure and four medium-pressure ports, allowing for comfortable and flexible hose routing. The DIN 200/300 bar connection ensures compatibility with standard diving cylinders.

Comfort and Safety with the ATX40 Second Stage

The ATX40 second stage is pneumatically balanced and ensures a consistently pleasant breathing experience. The efficient exhalation membrane optimises breathing performance, while the Venturi lever prevents accidental free flow at the surface. The large purge button is easy to operate, even with thick gloves. The comfortable Comfo-Bite mouthpiece helps prevent jaw fatigue. The compact exhaust deflector reliably directs exhaled air away from your field of vision. A patented heat exchanger provides protection against freezing by effectively dissipating cold.

Octopus ATX40Reliable Alternate Air Source with High Visibility

The Octopus ATX40 matches the second stage in both performance and features, offering optimal cold water protection thanks to its thermal transfer unit. The Venturi adjustment can be set to prevent accidental free flow. The Octopus is especially visible due to its bright yellow cover and LP hosean added safety benefit.
