The new MTX-R is based on the MTX, a regulator that was developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test. Innovations in design mean that the MTX-R regulator performs in almost freezing water at a depth of over 60 metres, something that very few other regulators on the consumer market can boast.With an innovative first stage design that helps to prevent ice build up around the diaphragm, the MTX-R is reliable, rugged and expedition ready
Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.
The regulators have been specially cleaned and assembled in our purpose built class 'J' (10,000) Clean Room using oxygen safe components and lubricants.
Nitrox equipment will be supplied in Europe in accordance with the EN 144-3 and the EN13949 which states that equipment sold in CEE (European Community) countries over 21% and up to 100% will be manufactured with the special M26 fitting.
