DIR Regulator Set – R4WW 1st Stage + TEC1 2nd Stage

Complete twinset configuration compliant with DIR standards, featuring two monolithic R4WW first stages with pre-oriented outlets and high-performance adjustable second stages.

The Tecline R4WW TEC1 DIR Style Regulator Set, available at DIR-STORE, is a technical breathing system specifically designed for divers in temperate or tropical waters who seek maximum geometric cleanliness combined with no-frills mechanical robustness. The two R4WW first stages feature a fixed monolithic body without a swivel turret, with pre-inclined LP and HP outlets to guide the twinset hoses perfectly parallel to the cylinders, reducing bulk behind the head. The WW (Warm Water) version eliminates heavy dry-chamber anti-freeze kits, making it ideal for summer marine layouts, travel, and warm technical dives.

Technical Features:

• Dual R4WW First Stages (Fixed Body Warm Water Edition): Constructed from robust chrome-plated marine bronze, the R4WW first stages utilize a balanced diaphragm mechanism optimized to maximize gas flow in non-freezing waters. The fixed inclined radial geometric arrangement of the outlets allows for impeccable DIR routing, guiding the hoses smoothly along the BCD's profile without forced bends or structural tension. Each first stage offers 4 LP and 2 HP ports.
• Dual TEC1 Second Stages (Simplicity and High-Flow): The two pneumatically balanced second stages instantly compensate for pressure variations within the cylinder, minimizing inhalation effort at any depth. The shockproof technopolymer casing is reinforced by a protective aluminum perimeter ring, and the classic design ensures extremely simple field maintenance.
• Flow Control and Safety: Both second stages integrate a lever for manual adjustment of the Venturi effect (essential for inhibiting accidental free-flows on the neck-mounted backup second stage) and a micrometric knob to calibrate breathing effort.
• Custom DIR Style Hose Geometry: The set includes high-quality LP hoses dimensioned precisely for their respective technical roles: a long hose (1.93 m, 2.00 m, or 2.10 m) for the primary second stage (the donor) and a short hose (0.61 m) for the neck-mounted backup.
