Außerdem zeichnen sich Mink Klauen-Vakuumpum- pen bei allen Anwendungen durch ihre hohe Energieeffizienz aus, die durch den Einsatz von frequenzgerelten Antriebs- motoren noch weiter gesteigert werden kann. Auf großes Interesse stieß die Extruder-Entgasungsanlage auf dem Messestand von Busch (Bild: Busch) 40 square meters booth, three Fimic fil- ters and fours sales manager. The K show has ended with great results for Fimic, with an imposing demand for more sophisticated filtrations with the aim of reaching a higher quality in the plastic recycled pellet. Fimic never ends its con- tinuous research and not only the company has considerably improved its core product, the RAS model, but it has also ad- ded to its range of solu- tions, a double filtration machine (the ERA) and the belt-type model (the NET). The RAS model built by Fimic is well known, with its punched or laser drilled screens, for managing highly contaminated materials, as for example coming from post-consumer sources. However, in some cases the material can be so contaminated, that the only possibility is to filter it twice, to get to the high quality needed, both for film or injection moulding applications. In order to avoid the n At the last K show, Fimic has intro- duced its latest innovation in filtration technology. During the whole show, Fimic had at disposal of the attendees a The new “NET” costs related to the necessity of two ex- truders or a gear-pump and a second fil- ter, Fimic has recently designed a self- cleaning filter (the ERA model) that can filter twice inside a single machine con- taining a double filtering chamber. Dou- ble filtration, because two different screens can be installed at the same time in the machine, the first with a coarser filtration, the second finer. Not only to protect the laser drilled screen (which cost is higher) used for the finer stage from possible glass or metal, but also to reach a higher quality thanks to the dou- ble passage. In some cases, the second filtration could be, instead of by scrap- ing, by back-flushing (in order to reduce the filtration down to 40 microns). This option gives the possibility of dealing with more demanding materials, like PET, that can now be automatically pro- cessed. If the customer prefers a belt filter, Fimic can now also offer its own belt solution, the NET model. This machine is generally the solution when the material is not highly contaminated (just few percen- tage of contamination), otherwise the cost of the mesh would be too high, or when there is a high level of aluminium, to allow an automatic change of the belt. In the NET Filter in fact, the belt is sup- ported by a rotating drum, that rotates
