SCUBAPRO MK25 Evo Din 300 – D420 Regulator

SCUBAPRO MK25 Evo Din 300 – D420 Regulator

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 DIN 300 First Stage Regulator.

The SCUBAPRO MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow regardless of how cold the water is.
Air-balanced flow-through piston design provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
SCUBAPRO’s exclusive patented Extended Thermal Insulating System (XTIS) makes this possible by fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.
Two high pressure and 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.

SCUBAPRO MK25 EVO DIN 300 First Stage Regulator Features

• 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.
• Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
• Weight: INT 232 (27.9 oz / 790g): or DIN 300 (20.1oz / 570g).
• Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.
