1ST STAGE DB4 WHITE 2 HP OUTLETS

• 2 high pressure ports.

• Compact machined first stage based on the expedition tested Apeks

DS4 platform.

• Break through, innovative over-moulded first-stage endcap and

environmental diaphragm helps prevent ice build-up that can cause

first stage free flow in extreme circumstances.

• Also protects the first stage from impact damage

• Large surface area heat exchanger diaphragm clamp helps increase

the gas temperature inside the first stage, resulting in improved

cold water performance.

• Unique over-balanced diaphragm design – as the diver descends,

the over-balancing feature allows the medium pressure gas in

the hose to increase at a faster rate than ambient. This results in

superior performance at depth.
