Scubapro MK19 EVO/D420

With the introduction of the new D420, Scubapro engineers have combined the iconic design of the original D-Series second stages with the latest advances in breathing performance technology. They then teamed it with the new MK19 EVO balanced diaphragm first stage to create a 21st century smooth, natural breathing regulator. 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 compact, lightweight MK19 EVO, with its environmentally sealed system, dry ambient pressure chamber plus user-friendly LP port swivel turret, this regulator system is uniquely well-suited to handling cold water and the harsh diving conditions often encountered by technical divers. This makes the MK19 EVO/D420 more tech-driven than the MK25 EVO/D420, while serving avid divers and Scubapro brand enthusiasts everywhere.

Scubapro MK19 EVO first stage:

• Air Balanced Diaphragm
  Delivers effortless airflow unaffected by depth, tank pressure or breathing rate.
• Environmentally sealed system
  Prevent Water and pollutants from fouling the inner mechanism.
• More Compact & Lighter design
  Updated design is substantially smaller and lighter than the orginal MK19 first stage regeulator.
• Externally adjustable intermediate pressure
  Allows authorized Scubapro service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage.
• Anti-Freeze Protection (AF)
  
• New Dry ambient pressure chamber
  Equipped with double spring, making it more compact and reliable.
• Chrome plated Brass Body
• Full metal body 
  Components assure the best thermal exchange.
• Compact dimensions for lightweight comfort
• Two opposite high pressure ports
  The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck.
• LP Port Swivel Turret
  Four High Flow Swivelling low pressure ports plus one axial Super High Flow Port maximize hose routing options.
  High flow ports deliver about 15% more air than conventional ports.
• DIN/INT first stage configurations
  To ensure worldwide compatibility, all Scubapro regulator systems are available in a 200bar INT version as well as 300bar DIN versions.
• Weight
  INT 232 Bar: 885g.
  DIN 300 Bar: 665g
• Airflow
  At 200bar: 6900 l/ min - 244 SCFM.
• Approvals
  EN250: 2014 - CE Certification according to European directive 89/686/EEC. More information, See Scubapro Manual.

Scubapro D420 Second Stage:

The perfect blend of rich diving history and cutting edge regulator technology, the D420 delevers top breathing performence with classic styling. It features a brand new balanced valve called the Progressive Flow Control Valve that delivers abundant airflow for the best breathing performence, with a natural smoothness not unlike what you might experience breathing on the surface. This technical jewel is a must-have breather for all divers and all dive scenarios.
