Description:Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
If you dive deep, dive cold, or often find yourself on silty bottoms or in less-than-pristine waters, the MK17 EVO/G260 is the reg system for you.
Engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism.
This new version is more compact than its predecessor yet delivers better breathing performance. Its improved internal design allows more airflow from the LP ports which have also been configured for optimum hose routing. It also offers an external intermediate pressure adjustment that allows technicians to maintain peak performance between service intervals without having to break down the first stage.
Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
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 ports maximize air delivery and hose routing options.
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.
Available in a 3364psi/232bar INT configuration.
Weight: INT 232 - 30oz/850g.
Airflow at 2900psi/200bar: 6900 l/ min - 230 SCFM.
Intermediate pressure (psi/bar): 130-142/9.0-9.8.
Nylon fiberglass design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
Anodized aluminum front cover ring adds resistance without adding weight.
Metal components provide increased resistance to freezing when diving in extreme water conditions.
High-flow exhaust valve reduces exhalation for better overall breathing comfort.
Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes.
Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
Airflow at 2900psi: 1800 l/min - 64 SCFM.
Maximum low pressure: 203psi/14bar.
