At K 2025, EREMA launched a POWERFIL brand innovation that sets new standards in melt filtration for plastics recycling. The new LF 812 high-performance filter has twice the screen surface area of the previous premium model, the LF 406, extending the series upwards.

Markus Huber-Lindinger, Managing Director of EREMA, presents the new LF 812 laser filter on the EREMA booth at K 2025.

Another new feature is the integration of the proven Lock & Change system for changing screens during operation in the Endurance filter, which handles the pre-filtration of heavily contaminated input streams such as unwashed materials.

"This latest development in our laser filter sees us take a decisive step towards meeting the growing demands for high throughputs in plastics recycling at the same time as achieving the highest quality of melt," said Markus Huber-Lindinger, Managing Director at EREMA.

Larger screen area

The new LF 812 laser filter, with 100% larger screen surface, boosts throughput or maintains throughput while using screens with finer filters, which is particularly advantageous for quality-driven applications. Thanks to the larger surface area of the filter, it is also possible to operate at lower pressure and with less thermal load.

Up to 5,000 kilograms of melt can be filtered per hour with the single version of the new laser filter. The single version of the LF 812 laser filter covers applications with throughputs that previously required multiple filter units.

Combined with the new INTAREMA 2021 TVEplus, which has a throughput of up to 3.5 tons per hour, the recycling system can operate with one continuous extruder without a cascade configuration.

Lock & Change system

POWERFIL also has a new feature – the integration of proven Lock & Change system into an Endurance filter.

The Endurance filter handles coarse pre-filtration and protects the laser filter when processing unwashed material or input streams that are difficult to clean. Lock & Change makes it possible to change the screen during operation without interrupting production.

In combination with the shut-off function on the Lock & Change system, the machine continues production even while one of the sets of screens is being changed. This increases system uptime and contributes to stable process control with challenging material streams.
