Atomic Z2 Balanced Piston Regulator High Performance and Value for Discerning Divers The Atomic Z2 Balanced Piston Regulator offers divers a compelling blend of high-performance breathing, robust construction, and exceptional value. While it shares many of the advanced design features of its sealed counterpart, this version provides a more accessible entry point into the world of Atomic Aquatics' renowned regulator technology. It’s an excellent choice for divers who prioritize smooth, effortless breathing and appreciate the quality engineering that Atomic is known for. At the heart of the Z2 lies a balanced flow-through piston first stage. This fundamental design ensures consistent intermediate pressure delivery to the second stage, regardless of the pressure remaining in your tank. This translates to a smooth and natural breathing experience throughout your dive, contributing significantly to diver comfort and safety. The first stage also incorporates Atomic's exclusive Jet Seat high-flow piston, celebrated for its reliability and minimal wear over time. This key component contributes to the regulator's consistent performance dive after dive. The second stage of the Z2 mirrors the high-quality construction found in Atomic's premium regulators. It features a balanced linear flow design, which works in harmony with the balanced first stage to deliver remarkably easy inhalation and exhalation. The demand valve body is crafted from zirconium-plated brass, providing excellent corrosion resistance in a critical component. Furthermore, the use of a titanium lever and sealing orifice enhances durability and ensures smooth, reliable operation of the valve mechanism. A durable, high-quality silicone rubber diaphragm further contributes to the second stage's responsiveness and longevity. The Z2 incorporates Atomic's patented Automatic Flow Control (AFC). This ingenious system automatically adjusts the airflow through the second stage to provide the optimal breathing resistance at any given depth. This eliminates the need for manual adjustments during your dive, allowing you to focus entirely on the underwater environment and your dive plan. For situations requiring manual control, such as strong currents or buddy breathing scenarios, a conveniently located soft over-molded rapid adjustment knob allows for quick and easy fine-tuning of the breathing resistance. The Atomic Z2 Balanced Piston Regulator is also Nitrox ready for mixtures up to 40% right out of the box, offering versatility for divers who utilize enriched air for extended bottom times or reduced nitrogen narcosis. The first stage is equipped with two high-pressure (HP) 7/16" ports and seven low-pressure (LP) 3/8" ports, providing ample connection points for your pressure gauge, dive computer transmitter, and other essential accessories.
