Second Stage TEC1 O2 (Green)

Pneumatically balanced second stage in O2 version with high-visibility green cover, designed for use with pure Oxygen and hyperoxic mixtures. Classic, compact, and lightweight design, EN250A certified for the coldest waters. Equipped with breathing effort adjustment, Venturi effect, and integrated heat exchanger.

The Tecline TEC1 O2, available on DIR-STORE, is an elite second stage for managing decompression mixtures and Oxygen in any environmental condition, including diving in icy waters.

The high-visibility green cover allows for immediate visual recognition of the hyperoxic/oxygen mixture during gas changes. Thanks to its pneumatically balanced design and the presence of a heat exchanger, this regulator ensures minimal inspiratory effort and a constant airflow protected from freezing. It fully complies with EN250A regulations, guaranteeing maximum safety and ergonomics on both stage tanks and complex configurations.

Key Features:

• O2 Version with Green Cover: Immediate and unequivocal visual identification for safe use with pure Oxygen and hyperoxic Nitrox.
• Pneumatically Balanced: Ensures smooth and natural delivery regardless of depth and residual first stage pressure.
• Dual Customizable Adjustment: Equipped with both a knob for adjusting the initial inspiratory effort and a lever for controlling the Venturi effect to prevent free-flow.
• Antifreeze Protection with Heat Exchanger: External aluminum ring and additional thermal radiator to dissipate cold and allow use in icy waters (EN250A approved).
• Compact and Ergonomic: Weighs only 250 grams and features an anatomical mouthpiece to minimize mouth fatigue during prolonged decompression stops.
