Lightweight, Compact, Efficient


Made in France

Unlike other rebreathers, the TRITON is chest mounted. This characteristic allows it great adaptation capacity.

The rebreather consists of a Kevlar® bag protecting the Counter-lungs and a 2.1kg filter of lime*.

The connections developed by M3S on the basis of a clip system guarantee proper assembly. As long as the connection is not fully engaged, it is impossible to put the clip in place. It is also impossible to reverse connectors, a dual keying system.

Breathing hoses are made of clear blue silicone with an anti-bacterial treatment.

The tip (DSV) has been designed to be lightweight in the mouth and easily handled. All plastic parts are manufactured in POM-C.

The 1.5L oxygen cylinder is attached to it under the bag.

3 oxygen sensors allow the analysis of the breathing gas. They are placed in a removable chamber which is inserted into the inhalation counterlung.
