Cressi MC9 SC/Compact Pro Regulator DIN300
2nd STAGE XS COMPACT
New greatly simplified single-hull second stage made of ABS + elastomer of really compact size (diameter of 6 cm) and extremely light (153 g). Its mechanism and development are perfectly planned to obtain the minimum number of components and great strength. It's a smart shopping option because of its combination of features - reliability - price - maintenance cost. It's suitable for maximum reliability uses and also as a travel regulator due to its lightness.
In the Pro version, the material of the body of 2nd stage integrates particles in its composition to improve the thermal conductivity and to avoid the freezing in cold environments. Homologation CE for use in cold waters (> 4 º) EN250/2000.
The specific calibration of the inhalation mechanism changes slightly the personality on air output according to Ellipse series, rewarding an abundant flow without the need to exploit Venturi effect, beyond the exquisite touch and sensitivity of these kinds of regulators. This feature provides a limited tendency to continuous flow on surface or during the placement of equipment into the water, excellent for schools and renting (both the octopus and the double regulator). However, the results of the features place it beyond regulators of highest range.
Asymmetrical frontal cap drilling. The water flow starts to push the diaphragm anti-clockwise direction to create its retraction perfectly in flat position and to make the lever decrease gradually in precise perpendicularity, regardless of conditions (flow, sudden moves, any face position…).
Exhalation effort particularly reduced without the need to minimize the diaphragm thickness. The restraint system design of the diaphragm guides the flow 100% channelled towards the nozzles of the exhaust tee, which benefits from a powerful Venturi effect that, in addition, helps to guide bubbles far from the diver visual field. The diaphragm it’s stuffed to avoid water filtrations when sharp turns happen or when jumping from the boat into the water.
Practically integral purge pusher, bigger between 80 and 400% than any other regulator in the market to facilitate purge manoeuvre, especially to inexperienced divers.
The cap assembly system by a 30º bayonet turn ensures a simple and safe mounting and dismounting, even to perform cleaning sand tasks beside the beach requiring no tools.
Reduced usage aging due to the finish of the casing, as a result of applying in the mold a new technology that obtains a nuanced appearance made of a microtexture of rounded profiles.
1st STAGE MC9 SC
1st stage to overbalanced membrane MC9, the most modern but, at the same time, of simple maintenance and very robust and trustworthy.
The thicknesses of the walls of the body have been optimized to reduce to the minimum its weight (380 g). A case of semiflexible elastomer protects the 1st stage of blows and erosions.
Seat HP of stainless steel AISI316. Apart from the possibility of substitution in case of deterioration on having realized the maintenance, the composition of the seat, much harder than the traditional brass of the fixed seats, it prolongs its useful life since it resists better the deforming action of the metallic microparticles than could introduce proceeding from the bottle.
Valve of polyurethane of high mechanical resistance, to the oils and to the hiperoxic mixtures.
The hypercompensation of the mechanism guarantees a slight increase of the intermediate pressure as it gets down the pressure of the bottle. The regulator supplies therefore its maximum level of services in the final phase of the dip, undoubtedly the most critical.
An advanced study of the traffic of the air and a chamber of exclusive distribution that canalizes the air volume directly to the exits LP has allowed to reduce to minimal levels the fall of pressure in forced breathings (0,5 bar), guaranteeing a use with high services in any situation.
Isolation and antifreeze SC (Sealed Chamber) kit that isolates completely the diaphragm and the spring from water contact, turning it into the perfect option to work in extremely low temperature conditions because it reduces the possibility of freezing in extreme conditions.
Specially effective filter with form of hat inserted without need of circlip.
2 HP and 4 LP outputs.
They're supplied in version INT (stirrup) and DIN 300 bar. The toe of the coil of the version DIN has been realized in stainless steel instead of brass to guarantee a major resistance in case of falls or blows.
