The breakers of the DFX series, thanks to their power and efficiency and to the right relationship between weight and power are suitable for secondary demolition work, excavations in quarry, work in urban areas, galleries, pipelines and railway tunnels and, concerning the biggest models, demolitions in open pit mining.
\nThe FX series starts from the DFX-14 up to DFX-40 breaker; DFX-14 and DFX-17 have neither membrane, nor possibility of manual adjustment of the frequency of blows.
