    Robust side plates

    Bolt-on plates for very demanding work, easy to maintain and repair.

  • 06

    CBE+ (Constant Blow Energy plus)

    Active control valve and tubular accumulator for maximum-power blows with a wide range of flow rates and back pressures.

  • 07

    Optimized pressure for scaling

    Working pressure specifically adjusted for scaling tasks.

  • 08

    Without tie rods

    Tie-rod-free design that guides the piston and aligns the tool optimally. Quick and safe maintenance without special tools.

  • 09
