Proven thousands of times over and now even more powerful with 50 percent larger screen surface area compared to the previous model. That is what highlights the new EREMA 2/406 laserfilter, which POWERFIL, a business unit of recycling machine manufacturer EREMA GmbH, is presenting at K 2022 in Düsseldorf.

"For applications with a focus on melt quality and filtration fineness, this increase in screen area ensures lower pressure and temperature at the same throughput rate, allowing even finer screens to be used for even better results in quality-intensive plastics applications," explains Robert Obermayr, Head of Business Unit POWERFIL, EREMA GmbH. If the throughput capacity of the recycling plant needs to be increased, a significantly higher rate of plastic melt can be filtered while maintaining the other parameters thanks to the larger surface area of the screen. Up to 9,000 kilogrammes of melt can be filtered per hour with the Quattro version of the new LF 406 laserfilter.

This variability also impresses customers. "The large surface area of the screen gives us more capabilities on our INTAREMA® TVEplus® 1714 machine. Finer filtration, higher throughput, and all this with a longer service life," says Jörg Schneeberger, CEO of Walter Kunststoffe GmbH in Austria, where the Laserfilter was tested with plastic film from the post-consumer household sector as input material. Further detailed optimisations of the LF 406 include simpler, safer removal and improved service life of the discharge screws, as well as the new cover.

"Plastic recycling has become a must-have, even for input streams with higher levels of contamination. Efficient filtration systems are therefore indispensable for achieving the specified melt quality using existing extrusion systems," says Obermayr. That is why POWERFIL also offers the proven EREMA melt filters as individual components for existing EREMA machines and third-party extrusion systems. The product range includes the SW RTF partial area backflush system and the laserfilter. The range is aimed at manufacturers as well as recyclers, because the high-performance filters can be used to process post consumer plastics as well as post industrial films with paper labels and PET. Both types of filter are particularly easy to integrate into an existing recycling plant and both are available in numerous sizes and variations. Whether the customer uses the robust backflush filter or the continuous high-performance laserfilter depends on the throughput and level of contamination of the material. The Laserfilter is ideal for heavy contamination. It handles impurity levels up to 5 percent and filtration as fine as 70 μm while continuously cleaning the screen with a scraper.

POWERFIL will also present the new 2/406 laserfilter and the full range of filters at the
K 2022 trade fair stand for the EREMA Group.
