Apeks DB4 1ST STAGE Regulator – 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. Reviews There are no reviews yet. Be the first to review “Apeks DB4 1ST STAGE Regulator.” Cancel replyYour email address will not be published.
