Apeks XL4+ Regulator - DIN
New from Apeks, the XL4+ regulator is designed with the cold-water exploration diver in mind.
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 technical exploration diver with a large amount of equipment. The XL4+ regulator is a high-performance option for those technical divers serious about weight savings.
Features
1st 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.
- With 2 HP ports and 4MP ports.
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.
- UV inhibitors to help prevent discolouration of the white materials
