The Scubapro MK21 C370 Regulator is a compact, high performance, fully balanced regulator. It may be small but it benefits from core technologies taken from a number of other high performing models including the flagship MK25 EVO first stage.
At about 20% smaller than the MK25 EVO first stage, the MK21 uses a modern, cutting edge design to make it smaller and lighter, making it an ideal choice for the discerning travel diver that needs to stay within a weight limit but doesn't want to sacrifice performance. The pneumatically balanced flow-through piston design ensures a constant and effortless flow of air is delivered to the two high pressure ports and four low pressure ports.
The C370 second stage is fitted with a pneumatically balanced valve for consistent performance regardless of depth. The compact housing is perfectly suited for travel diving and despite it's size still features both diver adjustable venturi and inhalation controls.
Features
FIRST STAGE
- Air-balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure or breathing rate.
- Polished chrome-plated marine grade brass body is close to 20% smaller than the MK25, making it an easy travel companion.
- Unique thermal exchange design with external fins optimises freezing resistance.
- Two high pressure ports, one on each side of the body, allow the first stage to be positioned either up or down.
- Standard "smart" hose routing cap offers four low pressure ports angled for more convenient hose routing ( /- 20å¼).
- Optional hose routing cap increases routing configurations with four angled low pressure ports (0°/30°) plus a fifth centralised high-flow low pressure port, ideal for technical diving.
- Redesigned yoke allows for easier mounting on a cylinder, and a redesigned cap protects components from water intrusion after the dive.
- Weight: INT 232: 780G; DIN 300; 570g.
- Airflow at 200bar: (l/min): >7500.
- Intermediate pressure: 9.0-9.8 bar
- Air-balanced valve for smooth inhalation effort at varying depths and supply pressures.
- Compact rugged fibreglass reinforced nylon casing and exhaust tee take up little space in a dive bag.
- Stainless steel frame on the front cover adds the SCUBAPRO signature.
- The poppet and lever allows the design to maintain the same overall size as the C350.
- The exhaust tee is based on the S620 Ti's design and contributes to better work of breathing (a 10% improvement over the C350).
- User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA).
- Large purge button is easy to activate, even wearing thick gloves.
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
- Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
- Weight: 171g.
- Airflow at 200bar: (l/min): 1600 bar
