The exceptionally compact MK21/C370 regulator set perfectly combines comfort and performance.
The MK21 is approximately 20% smaller than SCUBAPRO's flagship MK25 but uses the same technology. It has a modern look and is an excellent choice for traveling divers for its size and weight.
Simple, easy to use and reliable, the air-balanced C370 delivers consistent airflow. Ideal for recreational divers in general and traveling divers in particular. Its compact size and light weight also make it a great second stage for female and smaller divers. With one of these regulators in your diving bag you can go on the road with peace of mind.
Together, these first and second stages form a no-nonsense breathing system that delivers big performance in a small package.
Technical
first stage
- Air-balanced piston provides constant and effortless airflow regardless of depth, tank pressure and breathing rate.
- The shiny chrome-plated brass body is almost 20% smaller than that of the MK25 - ideal for travel.
- Due to the unique design with external ribs for optimal heat exchange, the first stage is optimally frost-resistant.
- The two high pressure ports on either side allow the first stage to be placed upright or upside down on the bottle.
- The standard 'smart' head has four low pressure ports that are angled for more flexible hose connection (+/- 20º).
- The optional head with four angled low-pressure ports (0°/30°) and a fifth high-flow low-pressure port makes the connection of the hoses even more flexible, ideal for technical divers.
- The new bracket makes connection to the cylinder easier and the new dust cap protects the internal components from water after the dive.
- Available for 232 bar INT or 300 bar DIN.
- Weight: INT 232: 780 grams; DIN 300: 570 grams.
- Airflow at 200 bar: 7500 l/min.
- Intermediate pressure: 9.0-9.8 bar.
second stage
- The air-balanced valve provides optimal breathing comfort at different depths and at varying tank pressures.
- The compact robust housing made of fiberglass reinforced nylon and the new compact exhalation piece take up little space in the diving luggage.
- SCUBAPRO logo in stainless steel on front hood.
- Thanks to the seat and lever mechanism, the second stage is no bigger than the C350.
- The exhalation piece is based on the design of the S620 Ti and contributes to making breathing even easier (10% better compared to the C350).
- The second stage has a button and a lever mechanism that allows the user to control the breathing resistance and VIVA (Venturi-Initiated Vacuum Assist) respectively.
- Large purge button that is easy to operate even with the thickest gloves on.
- The Superflow hose has an extra large diameter so that more air is supplied with each inhalation.
- Compact Hi-Flow mouthpiece provides better airflow and fits comfortably in large and small mouths.
- Weight: 171 grams.
- Airflow at 200 bar: 1600 l/min.
