For mixtures containing more than 40% Apeks Nitrox regulators are specially made and assembled and are suitable for 100% oxygen use. They have the M26 DIN fitting and the same features as the standard models with the same number apart from colour coding.

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%.

M25 fitting nitrox regs are available from GoDive for an additional £15 over the price for standard M26 versions.

 

Remember you may need an Oxygen compatible contents gauge if you are using mixes with a higher Oxygen content than air.
