MK17 EVO/S620 Ti

MK17 EVO/S620 Ti

Built to deliver a steady supply of air in harsh diving conditions, the MK17 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. It is more compact yet delivers better breathing performance than its predecessor.

Delivering excellent performance; the S620 Ti’s work of breathing has been reduced by 37% over the S600, providing effortless airflow under all dive conditions. The large purge button improves water circulation, and the exhaust tee directs bubbles out of the field of view. It’s a stellar combination can be relied upon to deliver top-line performance in all dive conditions.

Features first stage

• Air-balanced diaphragm delivers constant and effortless airflow unaffected by
  depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the
  inner mechanism.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent
  airflow in the coldest conditions.
• Substantial increase in airflow – 6900 l/min versus 6500 l/min – includes
  improved balance of air supply pressure.
• Two high pressure and four high-flow low pressure ports maximize air delivery.
• High-flow performance is available from all four LP ports which are configured for
  optimum hose routing.
• External intermediate pressure adjustment enables technicians to fine-tune
  performance quickly and easily.
• Weigh : INT 232: 860g; DIN 300: 640g
• Airflow at 200bar: (l/min): 242.
• Intermediate pressure: 9.0-9.8 bar

Features second stage

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply
  pressures.
• Rugged reinforced technopolymer case and front cover are able to withstand years
  of aggressive diving.
• Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
• Uses the S600’s large diaphragm inside a compact casing for maximum breathing
  sensitivity.
• Diaphragm fits inside a more compact casing for maximum breathing sensitivity.
• User controls include an easy-grip diver-adjustable inhalation effort knob and
  Venturi-Initiated Vacuum Assist (VIVA) lever.
• The exhaust tee increases performance while directing bubbles out of the field of
  view.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all
  mouth sizes, from largest to smallest.
• Super-flow hose features an oversized bore that allows more air to flow on each
  inhalation.
• Airflow at 200bar: 1850 l/min
• Weight: 179g
