We offer a range of regulators suitable for use with Nitrox and Oxygen (also known as oxygen enriched air or EAN).

As they leave the factory standard Apeks regulators are suitable for use with oxygen enriched gases ( i.e. Nitrox etc.) providing the oxygen content does NOT EXCEED 40%*.

For mixtures containing more than 40% Apeks Nitrox regulators are specially made and assembled at our factory and are suitable for 100% oxygen use.

Standard Apeks regulators can be professionally converted to oxygen service and oxygen compatibility kits are available to Apeks dealers together with instructions for O2 use.

Click on the links below for detailed specifications and features in the equivalent standard equipment.

* You need to check the regulations regarding Nitrox in your particular country as these may differ from Apeks standard policy. For example the European standards EN 144-3 and EN13949 state that any regulators purchased in the European Community countries which are for use with an Oxygen content of over 21% must use the special M26 fitting and the standard regulator fitting must not be used with mixes over 21%.
