Scubapro MK25 EVO/D420 System
Combining the iconic design of the original D-Series regulators with the latest advances in breathing performance technology, Scubapro engineers have created a 21st century regulator in terms of quality, reliability, performance and style. The new D420 features a brand new balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve. The highly efficient purge button is a technical jewel based on a new concept that gives the D420 its unique face. Teamed with the venerable MK25 EVO balanced piston first stage, this is a regulator system purpose-designed for today’s avid divers and Scubapro brand enthusiasts everywhere.
Scubapro MK25 EVO first stage:
- Air balanced flow-through piston
In a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Patented XTIS (Extended Thermal Insulating System)
Fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. Key insulation system components are visible in blue.
- New spring insulating coating
Body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
- Anti-freeze protection
Radically increases breathing reliability when diving in the most extreme water temperatures.
- Two opposing high pressure ports
Allow the first stage to be positioned either up or down.
- Five high-flow low pressure ports
On a swivel turret maximize hose routing options.
- External intermediate pressure adjustment
Enables technicians to fine-tune performance quickly and easily.
- International or DIN Confirguration
Available in either 232bar INT or 300bar DIN configurations.
- Weight
INT 232: 790g. / DIN 300: 572 g.
- Airflow
At 200bar: (l/min/SCFM): >8500/301
- Work of breathing
Results are below 0.49 J/L.
