Description
The Apeks XL4+ is especially well-suited for the technical exploration diver who prefers cold water climates. Compact and lightweight, it helps reduce jaw fatigue during long, cold dives. Designed with an innovative, over-moulded endcap in conjunction with the environmental diaphragm that helps prevent ice build-up. The XL4 makes an ideal stage regulator and is also an excellent high-performance option for the technical exploration diver who is serious about maximizing functionality and minimizing weight.
First Stage
2 high pressure ports.
Compact machined first stage based on the expedition tested Apeks DS4 platform.
Break-through, innovative over-molded 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.
Second Stage
High performance pneumatically balanced lever operated poppet valve.
Large, over moulded self-flushing and controllable purge button.
Ergonomic Venturi lever is easy to use and locate.
White flexible nylon braided hose has better cold water performance than traditional rubber hose.
Standard metallic hose connection for interchangeability.
Comfo-bite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place
