Weighing in at a tiny 905g, the XL4 is our lightest ever cold-water regulator. This compact regulator includes our latest cold-water innovation, an over-moulded first stage endcap that reduces ice build-up around the first stage. Ideal for divers wanting reduce the weight of their rig without a reduction in performance.
New from Apeks, the XL4 regulator is designed with the cold-water exploration diver in mind.
Weighing in at a tiny 905g (DIN version), the XL4 is our lightest ever cold-water regulator. Light on weight doesn’t mean light on features though. This compact regulator includes our latest cold-water innovation, an over-moulded first stage endcap that reduces ice build-up around the first stage. This technology greatly reduces the risk of a free flow in low temperatures. Cold water performance is further improved by heat exchangers on the first and second stage.
This regulator is perfect for the travelling diver who ventures off to all destinations from Silfra to Sulawesi that need regulators that are light weight, compact but dont compromise in performance and that can dive in all conditions and temperatures.
Features and Benefits
Compact machined 1st stage based on the expedition tested Apeks DS4 platform.
Break through, innovative over-moulded first-stage endcap & 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 1st 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.
