M-Ovas®, with fixed cutting unit – all important issues:

From now on the M-Ovas® is offered additionally with fixed cutting unit.

With the fixed cutting unit, the cutting efficiency increases and avoids ragging of materials. The close adjustment between shear plate and blades allows a reduced wear on shear plates.


  • Applicable in biogas and wastewater areas.
  • Allowable solid content for wastewater 2 – 7% and for biogas up to 12%.
  • All shear plate designs are available (norm: 55mm comb).
  • Greater safety of maintenance personnel, because a break motor isn´t needed anymore.


  • Minimized gaps of approx. 0.1 – 0.4 mm between shearplate and blades enable lower abrasion.
  • High cutting efficiency avoids ragging of materials, such as rags, long fibers, etc.
  • The use of a 4-winged blade increased the cutting frequency.
