High-performance cutting system

Even though wet wipes and toiletries must not be disposed in a toi-let, experience has shown that this regulation is often disregarded on purpose or unintentionally. In order to ensure operational safety even in this exceptional situation, the Gerios® has a unique and extremely powerful cutting system.

Precise cutting

The special construction of the cutting blade with 3 cutting edges and the cutting plate in combination with a cutting gap of less than 0,05 mm ensures reliable cutting of more solid materials and fibres. The design guarantees maximum comminution of solid materials with 1,200 cutting operations per second.

High qiuality materials

The high-performance cutting system is made of corrosion-resistant special steel 1.4112 with extreme hardness (67 HRC). The used ma-terials provide very high wear-resistance and guarantee correspond-ingly optimal cutting performance in the long-term.
