The 1st stage is ultra modern, but at the same time easy to manage, very reliable and durable. The thickness of the walls has been optimized to greatly reduce its total weight (380 g). A semi-flexible elastomer sheath protects the 1st stage from erosion, wear and tear.. In addition to being able to substitute it in case of deterioration during maintenance, the composition of the saddle, much harder than the traditional fixed brass saddles, prolongs its life as it is more resistant to the deformation caused by metal particles that can infiltrate from the tank., both to oils and to hyperoxic mixtures. The mechanisms hyper-compensation guarantees a light increase in the intermediate pressure as the pressure in the tank decreases. Therefore the regulator delivers the , which are undoubtedly the most critical. Advanced research on internal air circulation and an exclusive distribution chamber that channels the air volume directly to the LP ports has reduced the minimum pressure drop levels in labored breathing (0.5 bar), guaranteeing high performance in any situation. The optional isolation and anti-freeze SC (Sealed Chamber) kit completely isolates the diaphragm and the spring from contact with the water, making it ideal for use in extremely low temperatures and dirty waters. Highly effective flanged filter inserted without circlip. 2 HP and 4 LP ports. Provided in INT (yoke) and DIN 300 bar. The threading of the DIN version is in stainless steel instead of brass to guarantee better resistance against drops or bumps.
