Description

The Apeks XL4 Nitrox Regulator is the O2 clean version of the standard XL4 and has been specially prepared by Apeks in accordance with EN 144-3 and EN13949 which requires regulators used with oxygen percentages between 21% and 100% to be manufactured with the dedicated M26 fitting.

The 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 technical exploration diver with a large amount of equipment. The XL4 is a high performance option for those technical divers serious about weight savings.

The first stage uses a balanced diaphragm design with an environmental seal and is fitted with one high pressure and four low pressure ports to offer flexible hose routing options for a variety of diving disciplines. The second stage is compact and light with a pneumatically balanced valve with a diver adjustable venturi lever. Both stages are finished with green trim to identify the regulators as dedicated nitrox.

Features

1st Stage

Compact machined first stage based on the expedition tested Apeks DS4 platform.
Break through, innovative over-moulded first-stage end cap 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.
2nd Stage

Compact and lightweight second stage improves comfort and helps reduce jaw fatigue on long duration dives.
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.
Flexible nylon braided hose has better cold water performance than a 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.
Re-useable mouthpiece clip makes it simple to change mouthpieces in the field.
Durable and flexible rubber exhaust tee provides excellent bubble diversion.
