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 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.
