Description
Cressi MC9 SC 1st Stage is designed for cold water diving while remaining versatile for use in a wide range of environments. It combines a balanced diaphragm first stage with a Sealed Chamber cold water system to deliver consistent high performance in water temperatures below 10 degrees Celsius. The design focuses on reliability ease of maintenance and reduced weight without compromising durability.
Key Features:
Balanced Diaphragm First Stage: Delivers stable and reliable performance across varying depths and cylinder pressures.
Sealed Chamber Cold Water System: Environmentally sealed design protects against icing in cold water and contamination in silty conditions.
Hyper Balanced Membrane: Increases intermediate pressure slightly as cylinder pressure decreases to maintain peak performance at the most critical phase of the dive.
Optimised Lightweight Body Design: Engineered wall thicknesses minimise weight while maintaining strength and durability.
Chromium Plated Brass Construction: Light compact structure with internal components in stainless steel chromium plated brass and advanced thermoplastic resins.
Semi Flexible Elastomer Sheath: Protects the first stage from impacts and erosion during use and transport.
Stainless Steel AISI316 HP Seat: Harder than traditional brass seats to resist deformation from metallic particles and extend service life.
Replaceable High Pressure Seat: Allows straightforward replacement during servicing to maintain long term reliability.
Polyurethane Valve Construction: Offers high mechanical resistance and compatibility with oils and hyperoxic mixtures.
Optimised Internal Airflow System: Exclusive distribution chamber channels air directly to LP outlets to minimise pressure drop during forced breathing to 0.5 BAR.
High Capacity Conical Filter: Hat shaped filter design provides effective filtration without the need for a circlip.
High Pressure And Low Pressure Ports: Equipped with 2 HP outlets seven sixteenth UNF and 4 LP outlets three eighth UNF for flexible configuration.
Anti Pressure Drop Pneumatic Spring: Maintains consistent airflow during high demand breathing.
DIN And INT Compatibility: DIN threaded connection manufactured in stainless steel for increased resistance to impacts and compliance with EN ISO 1209 and EN 250 2014 standards.
Service And Calibration Pressure: INT version service pressure rated to 232 BAR with calibration pressure set to 10 BAR.
Weight Options By Connection Type: INT version weight is 650 g and DIN version weight is 510 g.
Cressi MC9 SC 1st Stage is a robust and dependable regulator designed for divers who require consistent performance in cold water and challenging conditions. Its sealed construction advanced airflow management and durable materials make it a reliable choice for demanding dive environments.
