MAAG Company
The MAAG Group comprises successful and renowned companies, each with their own impressive history. Automatik Plastics Machinery, Ettlinger Kunststoffmaschinen, Maag Pump Systems, Gala Industries, Reduction Engineering Scheer and Xantec Steuerungs- und EDV Technik are today the strong and innovative product brands of the MAAG Group.
The history of the MAAG Group thus begins in the late 19th century, with the establishment of Scheer as a metal foundry and machine factory in Stuttgart, Germany, in 1890. Maag Pump Systems was founded in 1913. Automatik Plastics Machinery was founded in 1947. Gala Industries was founded in 1959, and Ettlinger Kunststoffmaschinen in 1983. The youngest member of MAAG Group – Xantec Steuerungs- und EDV-Technik was founded in 1994. Over the decades, they have all grown into experts in the various fields of polymer production and processing.
All the members of the MAAG Group contribute their supreme expertise and years of experience in developing and manufacturing superb machines, plants, systems, and software – and will continue doing so in the future. The bundling of core competencies, industry best practices, the attentive maintenance of existing business relationships and creation of new ones, all provide the foundations for maximum customer satisfaction throughout the Group.

High Performance Melt Filter ECO
The continuous melt filters of the ECO series are mainly employed in PET and PA applications due to their special design and for filtering polymer feedstock from industrial waste with a low level of contamination or lightly contaminated post-consumer waste, as well as for clean virgin material. Our ECO melt filters are capable of processing a wide range of polymers. All solid or elastomer foreign particles such as gels, black specs, paper, wood, aluminum, copper, rubber, silicone or high-melting polymer composites are efficiently removed.
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 applicationExtremely 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
High Performance Melt Filter ERF
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.
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
