Regulator Set – R4WW 1st Stage + TEC2 2nd Stage

High-performance balanced single regulator set with R4 TEC WW wet chamber diaphragm 1st stage and TEC2 2nd stage, supplied with choice of hose, regulator bag, and EN250A certification for temperate waters (>10°C).

The Tecline R4WW TEC2 regulator set, available at DIR-STORE, is a lightweight, compact, and versatile system designed to provide superior breathing comfort for diving in temperate waters (>10°C). Combining the practicality of the R4 TEC WW wet chamber diaphragm first stage with the precision of the pneumatically balanced TEC2 second stage, this kit meets the strict standards of European regulation EN250A.

The unique wet chamber architecture, without an environmental membrane, avoids the "overbalancing" effect (gas cut-off at high altitudes), making the R4 TEC WW the perfect option for feeding rebreathers, stage cylinders, classic recreational configurations, and for travelers. The set comes ready-to-use with a red Tecline carrying bag and maximum customization options for hose type and length.

Main Features:

• Wet Chamber Diaphragm First Stage: Ultra-compact and lightweight structure. The absence of an external environmental membrane prevents over-balancing at deep depths.
• Ideal for Travel and Rebreathers: Perfect for travel configurations, stage cylinders, and feeding CCR systems.
• Pneumatically Balanced Second Stage: Smooth delivery and minimal breathing effort adjustable via micrometric knob and Venturi lever.
• DFS (Direct Flow System): Direct flow for immediate breathing response.
• Heat Exchanger and Teflon: Metal components of the second stage with internal Teflon coating and a heat exchanger for maximum operational comfort.
• Complete Customization: Choice of hose between high-resistance rubber or Proflex Tecline braided hose with custom length.
