MC9-SC/Compact Pro is designed to be used in cold water, making versatile to be used anywhere on any trip. Combine a 1st diaphragm stadium balanced with a cold water system (SC) sealed and a second light and compact stadium, which offers high performance in water with temperatures lower than 10 ° C | 50 F. The MC9-SC is the first phase with a very modern super compensated membrane but, at the same time, easy to maintain and very robust and reliable. The thickness of the walls of the body has been optimized to minimize the weight. A semi-reflected elastomer sheath protects the 1st stadium from bumps and erosions. The HP seat is made of AISI316 stainless steel. Apart from the possibility of replacement in the event of deterioration when performing maintenance, the composition of the seat, much harder than the traditional lens of the fixed seats, prolongs its useful life since it better resists the deforming action of the metal particles that can be introduced from the bottle. Polyurethane valve with high mechanical resistance, with hyperoxic oils and mixtures. The hypercompensation of the mechanism guarantees a slight increase in intermediate pressure when the pressure in the cylinder decreases. The regulator, therefore, provides its maximum level of performance in the final phase of the dive, without doubt the most critical. An advanced study of the circulation of the internal air and an exclusive distribution chamber that channels the volume of the air directly struggling LP has allowed the pressure fall in forced breaths to a minimum level (0.5 bar | 7.25 psi), ensuring use with high benefits in any situation. The sealing chamber is sealed to the environment, protecting it from icing in cold water and contamination from particulates in mild condition. Particularly effective hat filter inserted without the need for a brain. It has 2 high pressure doors and 4 low pressure. The wire of the DIN version was made of stainless steel instead of brass to ensure greater resistance in case of falls or shots. To obtain extremely high performance in low temperature environments, the 2nd Compact Pro stadium, in particular, is designed with a special thermo -social thermoplastic neopolimero capable of transferring heat such as metal by preserving the design flexibility, chemical resistance and physical and mechanical properties of a conventional thermoplastic. That is, it allows you to drastically reduce the weight by providing thermal conductivity on an equal with metal cases. Thanks to this material and a specially conceived safety valve, it can pass all tests for use in cold water with flying colors. It is compact (6 cm | 2.4 inches) and very light (153 g | 5.4 ounces) which makes it ideal for the trip. Service pressure: 232 bar | 3365 PSI. Calibration pressure: 10 bar | 145 psi. The regulator is completed with Octopus Compact Pro who has the same characteristics as the second stage but is yellow, like the tube, to be easily recognized under water. MC9-SC/Compact Pro + Octopus Compact Pro is designed and produced in Italy by Cressi, a pioneer of the Italian brand in underwater diving, snorkeling and swimming equipment since 1946. The product has been covered by a limited warranty of 2 years.
The underwater diving regulator is designed and certified to meet European standards for the consumption of cold water, guaranteeing versatility for any diving shipment in various locations. Light and high performance design for use in any condition and any position.
Combine a 1st diaphragm stadium balanced with a cold water system (SC) sealed and a second light and compact stadium, which offers high performance in water with temperatures lower than 10 ° C | 50 F.
The first stage of equipment has a light and compact structure in brass plated with chromium with internal components in stainless steel and thermoplastic resins. 2 HP – 4 doors LP.
It has a hypercompensation mechanism, ensuring a slight increase in intermediate pressure when the cylinder pressure decreases. This function provides maximum performance during the final critical phase of the dive.
