Typical applications are e.g.:
PET, PA 6, PBT, PTT, PEN, Co-PET, ABS, SAN, PS, PP, PE

  • Polymer melts with a viscosity of 100-2000 Pas
  • Common throughputs up to 30.000 kg/h
  • Filtration finenesses down to 10 µm

In the manufacture of polymers and pellets, filtration must remove coarse and discolored contamination, which is created during the process, and must ensure optical purity. Pressure spikes during screen changes must be avoided in order to avoid strand breaks. For this, Gneuss Filtration Systems offer tailor-made solutions and make continuous cost reductions in the production process, combined with top product qualities, possible.

The advantages of Rotary Filtration

  • Permanent consistent quality
    Gneuss Filtration Systems make permanent consistent quality levels without any compromises possible.
  • Ultra-fine filtration with new quality standards
    All the processing technical advantages of the RSFgenius, the SFXmagnus and the KSF make a fully-automatic filtration without increasing costs or production variations possible.
  • Short dwell time of the melt in the filtration system
    Due to the optimum rheological design of Gneuss Filtration Systems, the dwell time of the melt in the system is reduced and thus thermal stress is avoided.
  • Low operating costs
    With the fully-automatic filtration of the RSFgenius – with its high pressure cleaning of the filter elements – screens are automatically re-used 30 to 400 times (depending on the filtration fineness) without any additional costs.
  • No production interruptions, no machine downtime
    Changing screens of Gneuss Rotary Filtration Systems does not have any influence on the production process, thus quality variations and strand breaks can be avoided.
