    Demarec Breakers

    Robust Innovation = Low total cost of ownership.


    For excavators from 1,5 ton to 100 ton operating weight, Demarec DBC Series Closed Breakers have been developed in some of the toughest environments.

    The breaker includes a maintenance free energy chamber. Blank firing protection is guaranteed as well as shock absorbence at all sides of the extremely robust housing.
    The quiet operation is achieved due to the use of synthetic wear plates.


    All Demarec breakers come with two chisel tips of your own choice. They are mounted extremely easily and fast – ready for every operation!


    The tool is prepared to house an automatic greasing system, that is available already included as an option.
    Another option is the underwater or the tunnel set-up.
