Regulators

Tough, reliable and economical, the MK2 EVO is the perfect choice for novice and experienced divers alike, looking for a simple, go-anywhere regulator that won't put too big a dent in your wallet. When teamed with the R095, this reg system is reliable, easy to maintain and even easier to use.

The MK2 EVO is the only downstream piston style first stage in its price range to offer systems and internal components specifically designed to resist freezing in extreme cold-water conditions. The patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort, regardless of how cold the water. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the current MK2. The MK2 EVO is also more compact than the standard MK2, yet has a bigger piston that pumps out 15 percent more airflow from a smaller package, resulting in impressive breathing performance wherever you dive. 

The R095 is a modern second stage design based on the heritage of the time-honored R190. The R095 combines a classic downstream valve with a large diaphragm, functional purge button for smooth and easy operation.

The AC2 + COMPACT is a simple regulator for dive centres and rental programmes.

Highlights:

• 1 Stage:
• The AC2 1st stage can be used in water temperatures above 10°C and features a straightforward unbalanced piston design that is easy to service. With just one HP port, it’s ideal for divers who don’t rely on an air-integrated computer. This traditional 1st stage delivers a no-frills, dependable breathing experience, perfect for high-frequency recreational dives.Unique to Cressi is the AC2’s external 1st stage IP adjustment system. This allows service centres to fine-tune the intermediate pressure while the regulator is on the cylinder, providing a quick fix to keep it in use until the next service. The high-capacity conical filter is designed to trap cylinder debris, before it damages the internal components of the 1st stage.Compatible with parts from the AC25 and AC5 models, the AC2 shares a single maintenance kit for INT and DIN versions, simplifying and reducing servicing costs.
• 2ND Stage:
• The COMPACT 2nd stage is lightweight and comfortable, helping to reduce jaw fatigue on longer dives. A large purge button is easy for new divers to locate and the adjustable Venturi system has two options, a pre-dive mode to minimise free-flows at the surface and a dive mode for optimising performance underwater.With its impact-resistant front cover, anti-scratch surface and easy-to-maintain design, the AC2 + COMPACT is a practical and cost-effective regulator for entry-level divers and dive centres.

The Cressi T10 SC CROMO MASTER CROMO is a high-performance regulator designed for recreational and diving professionals exploring extreme cold-water environments.

Highlights:

• 1st Stage:
• The T10-SC CROMO 1st stage has a hyperbalanced diaphragm that adjusts airflow to match the surrounding water pressure. Requiring minimal inhalation effort, this creates a smooth, natural breathing experience at any depth, outperforming most regulators on the market.  Its environmentally sealed design keeps water and contaminants out, preventing freezing and protecting against debris ingress in silty waters, while also preserving the lubricants. The conical filter provides a larger surface area for efficient filtration, trapping more impurities and requiring less frequent maintenance, making it ideal for technical and frequent divers. With its durable chrome finish, this 1st stage offers long-lasting performance. 
• 2nd Stage:
• The MASTER CROMO 2nd stage is the perfect cold-water partner, with an internal heat exchanger that prevents ice formation inside the regulator. The elliptical design of the 2nd stage increases the surface area of the diaphragm, further reducing the effort needed to inhale, particularly during high-demand dives or at depth.A large breathing effort adjuster allows divers to fine-tune their airflow and the adjustable Venturi helps avoid free-flows at the surface or in strong currents. The MASTER CROMO features our Safe-Flex hose, which is incredibly flexible compared with traditional hoses.

Become one with the water. Welcome to the Zen of diving.

Highlights:

• 1st Stage:
• The balanced diaphragm MC11 1st stage features Cressi’s PressureSync technology, which maintains consistent Intermediate Pressure (IP) throughout each breathing cycle. This innovative design reduces pressure fluctuations, delivering one of the smoothest and most comfortable breathing experiences available. A high-capacity conical filter traps more impurities from the cylinder than a standard flat filter, protecting internal components, providing cleaner air and reducing maintenance needs.
• 2nd Stage:
• The ZEN 2nd stage has special Radial Pressure Openings that evenly distribute water pressure across the diaphragm, reducing free-flows and ensuring the 2nd stage delivers air only when needed, even in strong currents. The risk of a free-flow is further reduced thanks to the adjustable Venturi system, pre-dive mode minimises free-flows at the surface and dive mode optimises performance underwater.
