Cressi MC9 XS Compact Regulator

0.00

Cressi MC9 XS Compact Regulator is the premier travel regulator, packing maximum performance into minimum space. A true featherweight second stage, the XS Compact is built from lightweight techno-polymers to eliminate jaw fatigue. Easy to pack and easy to dive, the XS Compact includes dive/pre-dive Venturi switch for managing freeflow and maximizing performance at depth.

  • Asymmetrical frontal perforation. The flow of the water starts to push the membrane counter-clockwise so that its retraction is perfectly flat and the cam progressively descends perpendicularly, independent of conditions (currents, brisk movements, facial position, etc.)

  • Patented cam tilt. One of the main reasons for initial inspiratory effort is friction between the cam and the diaphragm. Xs Compact incorporates a new Cressi patent that reduces the friction coefficient from 0.2 to 0.001. The diaphragm's cam-disc friction is practically nonexistent thanks to the disc's polished Teflon covering and the cam’s pivot system which works entirely perpendicularly

  • Sliding bow. Safe and reliable system that completely voids the need for anchoring elements

  • Bayonet closure with a 30º turn without thread, no tools needed, ideal for dive centers and schools to facilitate small emergency cleaning operations

  • Broad cap safety lock, removable with no tools needed. Insertion-extraction movement in two different phases and angles to avoid accidental freeing in case of bumps or hits

  • The casing finish is achieved by applying a new technology in the mold that creates a variegated look on a micro-texture of rounded profiles, which reduces the appearance of ageing due to friction

  • Exhalation effort particularly reduced without having to reduce the thickness of the membrane. The design of the membrane retention system directs the 100% channeled flow towards the nozzles of the bow, taking advantage of a strong Venturi effect. Also, it works to direct the bubbles away from the diver’s field of vision. Embedded membrane to avoid water infiltration in case of brisk turns or jumps to enter the water

  • New ultra flexible hose covered in thermoplastic rubber to guarantee resistance to erosion

  • The polyurethane valve, very mechanically resistant, both to oils and to hyperoxic mixtures. 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 micro particles that can infiltrate from the tank

  • The thickness of the walls has been optimized to greatly reduce its total size and weight (380 g). A semi-flexible elastomer sheath protects the 1st stage from erosion, wear and tear

Cressi MC9 XS Compact Regulator

Cressi MC9 XS Compact Regulator is the perfect regulator for avid divers who love to travel. With the 2nd stage weighing in at only 145g, you'll have more luggage space for your travels.

1st STAGE MC9:

The 1st 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 optional 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. Provided in INT (yoke) and DIN 300 bar. The threading of the DIN version is in stainless steel instead of brass to guarantee better resistance against drops or bumps.

2nd STAGE XS COMPACT:

New ultra simplified monocoque second stage in ABS + elastomer, small (6 cm in diameter), very light (145 g) and robust, designed and built to have a minimum number of components. It is a smart buy due to its combination of performance, reliability, price and cost of maintenance. It is perfect for uses requiring maximum reliability and is an ideal travel regulator, given its lightness together with the the 1st stage MC5. It is also perfect for dive centers, as a work regulator with AC2, and as an addition to the high range MC9. The specific calibration of the inhalation mechanism slightly changes the air delivery as compared to the Ellipse series; the feel and sensitivity of these models is exquisite, with an abundant flow without needing to exploit the Venturi effect. This feature adds a scant tendency to freeflow on the surface and when positioning the equipment in the water, ideal for schools and rentals, octopus and double regulator. Nevertheless, the performance results put it at the top of the highest range of regulators. Asymmetrical perforation in the front cap. The flow of the water starts to push the diaphragm counter-clockwise so that its retraction is perfectly flat and the cam progressively descends perpendicularly, independent of conditions (currents, brisk movements, facial position, etc.). Exhalation effort particularly reduced without having to reduce the thickness of the diaphragm. The design of the membrane retention system directs the 100% channeled flow towards the nozzles of the bow, taking advantage of a strong Venturi effect. Also, it works to direct the bubbles away from the diver’s field of vision. Embedded membrane to avoid water infiltration in case of brisk turns or jumps to enter the water. Practically integrated purge button, between 80-400% larger than that of any other regulator on the market to facilitate purging, especially for beginning divers. Cap system assembly by a 30º bayonet turn, assuring very safe and simple assembly-disassembly, also while cleaning out sand on the beach, without the need of tools. Reduced ageing due to usage thanks to the casing finish, achieved by applying a new technology in the mold that creates a variegated look on a micro-texture of rounded profiles.
