Scubapro MK25 EVO / D420 Regulator

The MK25 EVO is Scubapro's thoroughbred race horse. Years of careful breeding has led to this seriously high performance version of the MK25 and features new anti-freeze coatings and components to further improve it's cold water performance and reliability. The MK25 EVO is fitted with two high pressure ports on either side on the main body and five high-flow low pressure ports mounted on a swivelling turret.

The D420 features 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 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.

Features

First Stage:

• Air balanced flow-through piston in a chrome-plated brass body
• Patented XTIS (Extended Thermal Insulating System)
• 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
• Two opposing high pressure ports
• Five high-flow low pressure ports on a swivel turret
• Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572.
• Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 130-142/9.0-9.8.

Second Stage:

• Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology.
• Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface.
• Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve.
• Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
• Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier.
• Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility.
• Large purge button is easy to reach and depress, with or without gloves.
• Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation.
• 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.
