High performance Melt Filters – The ECO Series
The continuous melt filters in the ERF series are suitable for materials with up to 16% by weight contamination and are guaranteed to remain in use for long periods without changing the filter. 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. Three different sizes enable throughputs from 150 to 10,000 kg/h depending on the application.
Suitable for Compounding, Recycling, Extrusion

Advantages
- Continuous operation with a constant pressure on the outlet side
- No need to replace the screen for several weeks, or possibly months, depending on the material and the application. Extremely low melt losses
- Absolutely clean filtration surface during the total time in operation
- Up to 1.5% contaminants removed (we recommend our ERF filter for higher contaminant contents)
- Completely closed system with no entrapped air
- Short contaminant residence times in the filter
- Consistent melt flow without dead zones or degraded polymer
- Suitable for all polyolefins, polystyrenes, PET and PA
- Better mixing and homogenizing of highly filled melts

BRF - Basic model for continuous melt filtration in modern plastics recycling
Basic model for continuous melt filtration in modern plastics recycling
The BRF is the entry-level model for continuous filtration technology. Its effective melt flow combined with an optimized discharge system ensures high quality in processing all common polymers including LDPE, LLDPE, HDPE, PP, PS, ABS, etc. with low to high contamination levels. Thanks to their robust screens, the new continuous melt filters of the BRF series also make a major contribution to cutting operating costs in day-to-day production – especially when processing melts with mineral components.

CSC-R - Screen changer with curved filter screens
MAAG’s CSC-R large scale screen changer with curved screens is designed for the use of one-way filter screens which do not require cleaning after the simple and safe screen change. The screen bearing pistons belong to MAAG’s modular filter system and its patented design use 75% of the piston surface as active filtration area. Also this filter execution can be installed for vertical or horizontal melt flow directly at the reactor discharge melt pump or pelletizer booster melt pump to avoid additional piping for reduction of melt residence time.
Suitable for Resin & Virgin Polymer Production
CSC-C - Polymer filtration for polymer production, polymer processing and extrusion
MAAG’s CSC-C large scale screen changer with candle filter elements is the right choice if short melt residence time, small footprint and a simplified candle change are required. Depending on the polymer type, melt viscosity, reactor throughput, and filter fineness, the screen changer size and number of pistons are customized to the application. The patented design allows the use of pleated micronex® candle filter elements with fiber metal felt (FMF) media, or cylindrical Multinex candles filter elements with interchangeable filter sleeves.
