The XL4 also makes an ideal stage regulator, perfect for the exploration diver with a large amount of equipment. It is a high performance option for the diver who is serious about weight savings.

APEKS XL4 DIN Regulator: First 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
  • Four 3/8″ UNF Threaded Low-Pressure (LP) Ports
  • One 7/16″ UNF High-Pressure (HP) Port

APEKS XL4 DIN Regulator: Second Stage

  • Compact and Lightweight
