If you want to be successful in the market, you have to be knowledgeable. Bundled know-how,
versatile experience, thinking ahead and developing better solutions in filtration technology
and realize that is our recipe for success.

Wilfried Leuders, Managing Partner of Leuders Extrusion Technologie GmbH, is a recognized and experienced specialist in filtration technology in all extrusion processes. For more than 25 years, Wilfried Leuders has been successfully operating in the industry in the areas of engineering / development and manufacturing as well as distribution of melt filters, screen changers, melt pumps and accessories for extrusion lines.

Function: High-performance melt filter type ERF / process pressure and volume constant

A rotating, tubular, perforated filter cartridge is flowed through from the outside to the inside. The contaminant
is retained on the filter surface and conveyed by the rotation to a scraper. This
lifts the contaminant from the filter and leads it directly to a discharge screw, without the contaminant
continues to be towed over the filter surface. Via this screw, the impurity cake reaches the secondary outlet.
Depending on the contaminant content, the filter speed and the speed of the discharge screw can be separated
be selected to achieve the largest possible, constantly open filter surface and thus high
To be able to discharge contaminant loads with the lowest melt losses.

Advantages:
• Fully automatic operation
• Consistently free filter surface
• short residence times
• Constant throughput
• Constant pressure conditions
• Constant melt viscosity
• Constant melt temperature
• No breaks or tolerance deviations – there is no filter change
• No consumption of screen fabrics, screen belts, etc.
• High reduction of material costs due to the addition of regeneration
• Low operating costs due to extremely long filter life
• Short arming time
• No backwashing or pumping in a collecting cylinder
• Soft particles (gums or gums) are removed quickly
• Schwallverschmutzungen be corrected
