Regulator Set – R4 1st Stage + REC1 2nd Stage

Single regulator set with 1st stage balanced diaphragm dry chamber R4 TEC and lightweight 2nd stage REC1, supplied with choice of hose, regulator bag, and EN250A certification for cold water.

The Tecline R4 REC1 regulator set, available on DIR-STORE, is an essential, reliable, and ultra-compact solution designed for recreational diving and use on stage and decompression tanks. The combination of the robust isolated R4 TEC diaphragm first stage with the REC1 second stage ensures high-level breathing performance that significantly exceeds the requirements of the European standard EN250A, even in particularly cold water.

The REC1 second stage stands out for its maximum ease of use and lightness, avoiding complex adjustments during diving while ensuring Venturi flow management. The kit comes complete with a red Tecline bag and total freedom in choosing the type and length of the hose.

Key Features:

• Balanced Diaphragm First Stage: Constant performance and smooth delivery at any depth and tank pressure.
• Antifreeze Isolation (Dry Chamber): Sealed dry chamber with additional cooling kit for maximum protection against freezing in cold water (<10°C).
• Essential and Lightweight Second Stage: Polyamide construction weighing only 195 g, designed to minimize jaw fatigue.
• Intuitive Venturi Lever: Smooth control of the Venturi effect to prevent free flow on the surface without the need for additional adjustments.
• Wide Exhaust Port: Enlarged exhaust deflector to effectively direct bubbles away from the diver's field of view.
• Configuration Versatility: Ideal configuration for decompression/stage tanks and excellent for single tanks.
• Hose Customization: Choice between high-resistance traditional rubber and ultra-flexible Proflex Tecline braided hose with custom length.
