The high-performance melt filters from the ERF series from Ettlinger meet the demand for recyclates of the highest quality, which are a highly sought-after commodity in the plastics processing industry. The melt filters from the ERF series from Ettlinger are a cost-effective solution for providing corresponding product quantities for the recyclable material cycle.

The manufacturer's flagship is the powerful ERF 1000. When processing easy-flowing materials including the injection moulding applications, its four rotating, perforated drums can filter up to ten tonnes of plastic melt per hour. The system's benefits include continuous operation in a stable process at consistent pressure and long operating times without filter changes.

If throughputs lower than those provided by the ERF 1000 are sufficient, the ERF 350 (up to more than 3,000 kg/h) and ERF 500 (up to 6,000 kg/h) offer alternatives to meet such requirements. All three sizes are designed for energy efficiency and are suitable for filtering common thermoplastics, including soft PVC and the proportion of contaminants such as paper, aluminium, wood, elastomers or high-melting polymer composites can be up to 16 per cent.

Thanks to their compactness, they are also very suitable for retrofitting existing extrusion lines. Typical applications range from recycling to sheet and film extrusion and compounding. In film recycling, in particular, the finest mesh size of 60 µm opens up possibilities for achieving benchmark qualities.
