First Stage F50 - Viton

Balanced diaphragm regulator with lamellar radiator head, ideal for cold water, advanced octopus configurations, and available with a 232 bar or 300 bar DIN connection.

The Scubatec F50 First Stage, available on DIR-STORE, is a high-quality balanced diaphragm regulator designed to offer maximum safety and reliability even at great depths. Entirely made in Italy, this model stands out for its integrated lamellar radiator on the main body head, a fundamental engineering solution to optimize thermal exchange and counteract internal temperature drops due to gas expansion. It is the perfect choice for advanced recreational diving and for those seeking an ultra-efficient independent air source system (Octopus).

Key Features and Benefits:

• Balanced Diaphragm Technology: Ensures excellent breathing performance with a perfectly constant intermediate pressure calibrated at approximately 10 bar (working with upstream pressures up to 300 bar). Guarantees an abundant, smooth, and effortless airflow at any stage of the dive.
• Lamellar Radiator Head: Specifically designed for use in cold or contaminated water. The lamellar radiator increases the metallic contact surface with the external environment to prevent freezing. For extreme winter or under-ice conditions, it is pre-arranged for the optional installation of the sealed Anti-Freeze Kit.
• Rational Outlet Layout (4 LP / 2 HP): Features 4 low-pressure (LP 3/8” X 24 UNF) outlets calibrated to cleanly and ergonomically supply the primary second stage, octopus, BCD, and dry suit, and 2 high-pressure (HP 7/16” X 20 UNF) outlets for the simultaneous connection of analog gauges and computer transmitters.
• Dual DIN Connection Option (232 / 300 bar): In full compliance with European standard EN 250:2014 and ISO 12209, the regulator can be purchased with either a DIN 232 bar threaded connection or a high-pressure DIN 300 bar version, ensuring exceptional mechanical sealing free of micro-leaks.
• O-Ring Compound Choice (NBR / Viton): For maximum customization based on the breathing mixture used, the first stage can be configured as standard with NBR compound O-rings or in the elite version with Viton O-rings and oxygen-compatible grease.

Why buy the Scubatec F50 first stage?

• Excellent for advanced Octopus configurations: Thanks to the precision of the balanced diaphragm system and the 4 symmetrically arranged LP outlets, it effortlessly handles the simultaneous air demand of two second stages, offering maximum stability in emergency flows.
• Ideal solution for cold water and thermoclines: The native thermal protection of the head radiator represents a huge step forward for the safety of divers who regularly dive in lakes, springs, or cold seas.
• 100% Made in Italy reliability and spare parts: Excellent structural robustness, precise machining tolerances, and quick and economical routine maintenance thanks to the full availability of Scubatec spare parts kits.
