MC 9 SC First Stage:

• Overcompensation diaphragm 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.
• HP saddle in AISI316 stainless steel. 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.
• Polyurethane valve, very mechanically resistant, both to oils and to hyperoxic mixtures.
• The mechanism¡¦s hyper-compensation guarantees a light increase in the intermediate pressure as the pressure in the tank decreases.
• Therefore the regulator delivers the maximum level of performance in the final phases of the dive, 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 standard 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.

Ellipse Balanced Second Stage:

• Many of the exclusive technical characteristics of Ellipse, covered by 4 international patents, have been transferred to this new second stage.
• Ellipse Balanced has a slightly larger casing which is made from a sound absorbing material, and a new diaphragm that further improves the already very low inhalation effort of Ellipse.
• The weight is very low (the lightest in the category).
• The pneumatic balancing system of the piston allows for constant performance at any depth and with any air pressure in the tanks.
• An easy grip knob allows for the instant adjustment of the inhalation effort, even when wearing gloves, thus regulating it as first regulator or as spare regulator depending on the preferences of the user and the required use.
• The regulation system is protected by a double seal and is fully protected from contact with water, thus maintaining smooth rotation even over time.
• A small lever, located in the upper part of the casing, acts as a flow deviator and allows the Venturi effect to be adjusted.
• When placed in position (-) it functions as pre-dive, for getting into the water and the first stages of the dive, whilst when moved to (+) it allows the regulator to develop its maximum performance.
• An internal heat exchanger optimises the performance of the regulator even in cold waters.
• The special study of air flows inside the casing has meant that absolutely natural, smooth and very silent breathing has been obtained.
• The standard release baffle can be directly replaced by the user for a larger model, which pushes the bubbles further way from the diver¡¦s face.
• The possibility of quickly removing the entire mechanical part from the casing significantly aids maintenance operations.

Description:

Pairing of balanced and adjustable second stage Ellipse Balanced with the hyper-balanced 1st stage MC9 SC. The user can adjust both the inhalation effort and the Venturi effect (dive / pre-dive) at any time during the dive. The 1st stage MC9 SC is identical to model MC9, but with a special Seal Chamber which completely isolates the diaphragm and spring from contact with water. Ideal for diving in waters that are rich in suspension and mineral salts, for archaeological work, for potholing and diving in cold waters.
