MAAG – High Performance Melt Filters – The ERF Series
Our ERF melt filters are capable of processing a wide range of polymers (e.g. LDPE, LLDPE, HDPE, PP, PS, ABS, PC / ABS, TPE, TPU, POM). All solid or elastomer foreign particles such as paper, wood, aluminum, copper, rubber, silicone, or high-melting polymer composites are efficiently removed.
The classic application for ERF melt filters is repelletizing lines, but they are also successfully employed for sheet and profile extrusion. ERF melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Four different sizes enable throughputs from 150 to 10,000 kg/h depending on the application

Key Features
- Fully automatic, continuous operation
- Up to 18% contaminants removed
- Extremely low melt losses
- More reliable processing due to constant pressure at the filter outlet
- No need to replace the screen for several weeks, or possibly months, depending on the material and the application
- Completely closed system with no entrapped air
- Short contaminant residence times in the filter
- Very simple replacement of the scraper from outside using a hydraulic cylinder
- Elastomers (rubber, silicone) are efficiently filtered and discharged before they have a chance to be forced through the filter screen
