Description
Cressi MC9 1st Stage is a lightweight balanced diaphragm regulator designed for reliable high performance diving in demanding conditions. Made in Italy, it combines advanced hyper balancing with optimised internal airflow to maintain consistent intermediate pressure throughout the dive, particularly during the most critical final phase.
Key Features:
Balanced Diaphragm First Stage: Ensures stable and consistent performance across varying tank pressures.
Hyper Balancing System: Provides a slight increase in intermediate pressure as cylinder pressure decreases to maintain peak performance at the end of the dive.
Optimised Airflow Chamber: Directs air volume straight to the LP outlets to minimise pressure drop during forced breathing to 0.5 BAR.
High Pressure And Low Pressure Ports: Configured with 2 HP outlets seven sixteenth UNF and 4 LP outlets three eighth UNF for flexible hose routing.
Lightweight Optimised Brass Body: Wall thicknesses are engineered to reduce overall weight without compromising strength.
Electroless Nickel Plated Brass Construction: Enhances durability and corrosion resistance in demanding marine environments.
Stainless Steel AISI316 HP Seat: Harder than traditional brass seats to resist deformation from metallic microparticles and extend service life.
Replaceable High Pressure Seat: Allows substitution during servicing to maintain long term reliability.
High Capacity Conical Filter: Electroless nickel plated filter improves air delivery and protects internal components.
Anti Pressure Drop Pneumatic Spring: Maintains airflow stability during high demand breathing.
Stainless Steel Setting Spring: Features micropeening treatment for improved fatigue resistance.
Replaceable Cylinder With AC16 Properties: Provides anti friction and anti corrosion performance.
Elastomer Protective Case: Semi flexible elastomer cover protects the first stage from impacts and erosion.
High Flow Capacity: Delivers a flow rate of 4500 litres per minute for demanding dive conditions.
Yoke Version Specifications: Service pressure of 232 BAR and calibration pressure of 10 BAR with a yoke version weight of 590 g or 20.81 oz.
Cressi MC9 1st Stage is engineered for divers who demand dependable airflow, reduced breathing effort and long term durability. Its refined internal design and robust materials make it a reliable choice for consistent performance in a wide range of diving situations.
