DIR Regulator Set – F32 Anti-freeze 1st Stage + FX3 2nd Stage + Pressure Gauge

Complete DIR-standard configuration for twinset. Includes two F32 balanced diaphragm first stages with integrated anti-freeze kit, 360° swivel turret and 5th axial port, pneumatically balanced FX3 second stages, metal pressure gauge, and technopolymer hoses.

The Scubatec F32 Anti-freeze FX3 + SPG DIR Set Regulator Kit, available at DIR-STORE, is a professional-grade breathing system, entirely Made in Italy, specifically developed for technical divers who face the harshest conditions, such as cold water or ice diving. The heart of this set is the F32 first stage, a balanced diaphragm regulator equipped with a structural Anti-freeze Kit that completely isolates the internal mechanisms, preventing the risk of accidental free-flow. Thanks to the 360° swivel turret and the 5th axial LP port, this package ensures precise, clean, and hydrodynamic hose routing on twinset configurations, allowing the hoses to run perfectly parallel to the cylinders.

Technical Specifications:

• Dual F32 Anti-freeze First Stage (Insulated Diaphragm and Arctic Protection): Constructed from high-quality chrome-plated marine brass, the F32 first stages utilize a balanced diaphragm mechanism assisted by a sealed dry chamber with high thermal insulation. This special Anti-freeze Kit prevents the formation of ice crystals on the springs and internal moving parts, ensuring a constant intermediate pressure (approx. 10 Bar) even at temperatures below 4°C. The 360° rotating turret integrates 5 LP ports (one of which is axial on the regulator head), eliminating any hose twisting behind the neck and ensuring freedom of head movement. Each first stage offers 5 LP and 2 symmetric HP ports.
• Dual FX3 Second Stage (Pneumatic Balance and Smooth Delivery): The FX3 second stages are pneumatically balanced to ensure minimal, soft, and constant inspiratory effort, independent of depth or residual tank pressure. Built with a high-resistance thermoplastic technopolymer casing (lightweight, shockproof, and corrosion-resistant), they house internal valves and mechanisms made of high-quality chrome-plated brass to ensure maximum longevity and operational precision.
• Dual Precision Adjustment: Both FX3 second stages feature a lever for manual adjustment of the Venturi effect (Dive/Pre-Dive), essential for preventing continuous free-flow when the regulator is not in the mouth (such as on the backup hanging around the neck). They also integrate an oversized micrometric external knob for calibrating the initial breathing effort, easily operable even with very thick dry gloves.
• 52 mm Metal SPG Technical Pressure Gauge: The kit includes a professional dive pressure gauge with a chrome-plated brass case, tempered glass, and a highly legible luminescent dial, supplied complete with a swivel pin.
• Heavy-Duty Technopolymer Hose Kit: In line with a pure DIR configuration, the set uses robust black rubber/thermoplastic hoses with high thickness (standard 9/16" connection), ideal for ensuring hydrodynamic stability and a natural vertical descent of the layout along the body:
• Primary Regulator LP Hose (Long Hose): 1.93 m
• Backup Regulator LP Hose: 0.56 m / 0.61 m
• Pressure Gauge HP Hose: 0.57 m / 0.60 m
