The Apeks XL4+ Regulator Set 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 Apeks XL4+ also makes an ideal stage regulator, perfect for the technical exploration diver with a large amount of equipment.
The Apeks XL4+ regulator is a high-performance option for those technical divers serious about weight savings.
Apeks XL4+ First stage
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.
Apeks XL4+ 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.
Compatible with XL4 Octopus (See page A25).
