Ocea XL4 1st Stage Regulator.

OCEA XL4 1st STAGE

The Apeks XL4 is a compact lightweight regulator suitable for diving in all environments including cold water locations. Its design and low weight help reduce jaw fatigue on long dives. The XL4 also makes an ideal stage regulator, perfect for the exploration diver with a large amount of equipment. It is a high performance option for the diver who is serious about weight savings.

First Stage

• 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.
