Apeks Nitrox XL4

Apeks Nitrox range of regulators opens up the most extreme of dive environments. They let you dive for longer and enjoy extended bottom times. But what is Nitrox?
Nitrox is the name for a wide range of gas mixtures with an oxygen concentration higher than the standard 21%. Because there is less nitrogen in the mix the chance of decompression sickness is reduced allowing you to explore the depths for longer.

Apeks Nitrox XL4 is a compact, lightweight technical regulator designed to handle to abuse of regular diving. The body of the DB4 1st stage is forged from a single piece of chromed brass, while the XL4 2nd stage constructed using the latest of composite technology ensuring it’s resistant to damage and tremendously light.

The DB4 1st Stage is environmentally sealed. This prevents ice buildup in the system allowing it perform flawlessly in cold environments; it also protects contaminants such as bacteria gets in and spoiling your air supply.

As you’d expect from Apeks the Nitrox XL4 is kitted out for technical diving. The overbalanced diaphragm allows the XL4 to perform well in deep water by counteracting the effects of ambient water pressure on your hoses.

The XL4 2nd Stage is pneumatically balanced for consistent and effortless breathing throughout your dive. The diver controllable venturi switch allows you to safely prevent free flow ensuring you don’t waste air when not using the regulator.

The Comfo-Bite mouthpiece features a bridge that sits across your palate. This provides support for the 2nd stage, reducing stress on your jaw and eliminates dry mouth.

Unlike many nitrox regulators, the Nitrox XL4 has been rigorously oxygen cleaned, meaning you can use nitrox blends beyond the 40% limit typical of most dives. In Europe, the Apex Nitrox Regulators are sold with an M26 connection
