DIR Regulator Set – 1st Stage V1 + 2nd Stage TEC2

Complete twinset configuration compliant with DIR standards. Includes two monolithic V1 ICE diaphragm first stages with "V" hose routing and ultra-compact, top-of-the-range second stages.

The Tecline V1 ICE TEC2 DIR Style Regulator Set, available at DIR-STORE, represents the perfect synergy between the extreme hydrodynamics of an asymmetrical "V" first stage and the advanced fluid dynamics of a premium second stage. Developed to meet the demands of the most discerning technical divers and cave divers, this kit allows for precise and clean hose routing on twinsets. By eliminating hose crossovers behind the head, the system ensures maximum freedom of movement and optimal visibility during valve drills. Certified well beyond the strict European standard EN250A requirements, it offers impeccable delivery even in icy waters or under high respiratory stress.

Technical Specifications:

• Dual V1 ICE First Stage ("V" Geometry and Arctic Protection): Constructed from high-quality chrome-plated marine bronze, the V1 ICE first stages feature a balanced diaphragm mechanism assisted by a sealed dry chamber and an integrated Cold Kit. This total insulation protects the springs and internal components from freezing and sediment. The "V"-oriented outlet layout routes the hoses straight along the BCD bag profile, drastically reducing the risk of entanglement. Each first stage offers 4 LP and 2 HP ports.
• Dual TEC2 Second Stage (DFS Technology and Ultra-Comfort): The pneumatically balanced second stages implement the innovative DFS (Direct Flow System) direct flow system. This architecture optimizes the internal gas fluid dynamics, minimizing the overall work of breathing (WOB) at any depth, regardless of the residual pressure in the cylinders.
• Anti-Freeze and Mechanical Shielding: The structural polymer casing is frontally shielded by a solid stainless steel ring to resist strong mechanical stress or impacts in caves. The internal metal parts benefit from a dedicated heat exchanger and a protective non-stick Teflon coating.
• Dual Adjustment and Safety: Both second stages feature a lever for Venturi management (essential for inhibiting accidental continuous flows on the second stage positioned at the neck) and a micrometric knob for manually calibrating the inspiratory effort.
• Custom DIR Style Hose Geometry: The set includes high-quality black LP hoses precisely sized 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 backup.
