Ettlinger, part of the Maag Group and Dover, has unveiled its ERF 1000 high-performance melt filter for very high throughputs of up to 10,000 kg/h in recycling applications for plastic materials.

The four filter drums provide a total of 6280 cm² of filtration surface which is twice as much as the ERF 500 and remove foreign particles from polymer feedstock containing up to 18% contaminants.

ERF filters are now available in four different sizes, starting with the ERF 200 for throughputs up to 800 kg/h, to the new ERF 1000, which can reach a maximum of 10,000 kg/h, depending on the application. The ERF 1000 is designed for virtually any kind of plastic that can be recycled, including packaging plastics such as LDPE, LLDPE and HDPE.

It is self-cleaning and works with a rotating, perforated drum, through which there is a continuous flow of melt from the outside to the inside. A scraper removes the contaminants that are held back on the surface and feeds them to the discharge system.
