XL4 - Oxygen Regulator
The Apeks XL4 is a compact, lightweight regulator suitable for diving in all environments including cold water locations.
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.
Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.
The regulators have been specially cleaned and assembled in our purpose built class 'J' (10,000) Clean Room using oxygen safe components and lubricants.
Nitrox equipment will be supplied in Europe in accordance with the EN 144-3 and the EN13949 which states that equipment sold in CEE (European Community) countries over 21% and up to 100% will be manufactured with the special M26 fitting.
We can convert the 1st Stage to DIN please select it when ordering.
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.
