Set Oxygen 100% R4 + TEC2 - DIN 26x2

Stage/Decompression regulator set for Pure Oxygen (100% O2) with DIN M26x2 connection, equipped with an R4 O2 diaphragm first stage with integrated antifreeze, a pneumatically balanced TEC2 O2 Green second stage, a 100 cm LP hose, and a carrying bag.

The Tecline R4 TEC2 100% O2 regulator set, available at DIR-STORE, is a high-end decompression configuration designed for technical divers seeking breathing performance superior to EN250A standards and extreme thermal reliability during decompression stops with pure Oxygen or hyperoxic mixtures.

The R4 O2 balanced diaphragm first stage (with built-in anti-freeze system) works in perfect synergy with the TEC2 O2 Green second stage. Weighing only 260 grams, the TEC2 is a high-performance pneumatically balanced second stage, featuring an additional heat exchanger, Teflon coating on metal components, and dual adjustment (Venturi effect and inspiratory effort) via a DFS (Direct Flow System).

Key Features:

• R4 O2 Diaphragm First Stage with Antifreeze: O2-cleaned balanced diaphragm mechanism, equipped with integrated thermal anti-freeze protection for maximum safety in cold waters.
• Tecline TEC2 O2 Green Second Stage: Pneumatically balanced design with DFS (Direct Flow System), stainless steel outer ring, and a body with high thermal, mechanical, and chemical resistance.
• Advanced Anti-Ice Technology: Metal components of the second stage coated with Teflon to prevent ice formation, combined with an additional heat exchanger for cold waters.
• Customizable Dual Adjustment: Knob for inspiratory resistance adjustment and lever for Venturi control, for impeccable breathing comfort.
• Standard M26x2 Connection (EN 144-3): Standardized and exclusive threading to prevent connection errors with cylinders filled with air or other mixtures.
• Flexible LP Hose (100 cm): Optimal 1-meter length for perfect routing of the second stage on the decompression cylinder.
• Carrying Bag Included: Original Tecline green protective case for safe storage and transport.
