Built to deliver a steady supply of air in harsh diving conditions, when the going gets rough, the MK17 EVO/A700 gets going. The new 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 The A700 offers extraordinary breathing performance, including effortless inhalation and an ease of exhalation that is unmatched, all in a precision-handcrafted, full-metal package.
MK17 First :
Air balanced diaphragm design 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 trouble-free operation in the coldest conditions.
Two high pressure, two low pressure and two high-flow ports maximize air delivery and hose routing options.
External intermediate pressure adjustment enables technicians to fine-tune
performance quickly and easily without the need for disassembly.
Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
Weight: INT 232 – 30oz/850g; /DIN 300 – 22oz/625g.
Airflow at 2900psi: 6500 l/min – 230 SCFM.
Intermediate pressure (psi/bar): 130-142/9.0-9.8.
A700 Second Stage:
Rugged full metal case and valve housing are able to withstand years of aggressive diving.
Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
High-flow exhaust valve allows air to exit more freely and lowers the exhalation effort while directing bubbles away from your mask.
Super-flow hose features oversized bore (larger inner hose diameter) to increase airflow.
Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow. Weight: 9.3oz/265g.
Airflow at 2900psi: 2000 l/min – 71 SCFM.
Maximum low pressure: 203psi/14bar.
