system is designed to handle contamination levels of up to 15% by weight, depending on pollutant type, making it particularly well suited for PCR applications. Inside the filtration


chamber, two opposing screens work in conjunction with a rotating scraper disc and six inter- changeable blades which continu- ously remove contaminants and transfer them to a single independent discharge screw. This configuration maintains stable pressure during operation, minimises material loss, and prevents contaminants from re-entering the melt stream. Operational efficiency is another key focus.

and a throughput of up to 4,000 kg/h, the Cobra filter offers high performance density and process stability. BBE also offers VacuFil, a fully integrated system for innovative PET LSP (liquid state polycondensation)


Break Machinery says installation of its Duo systems can result in production increases of up to 20%, waste reductions of up to 50%, and downtime reduction of up to 75%, depending on material and line configuration. The continuous self-clean- ing mechanism extends screen life and reduces consumable usage, while the system’s compact filtration chamber supports high productivity. From a controls perspective, the HMI enables tempera- ture management, pressure or torque operating modes, and cleaning parameter adjustment. Operators can store and recall recipes, and integra- tion via OPC-UA allows communication with plant PLCs, SCADA, and management systems. Remote monitoring capabilities further support diagnostics and technical assistance. For materials with lower contamination levels,

Break Machinery also offers an optional Eco-Mode configuration. This vacuum-based cleaning system uses mesh screens instead of laser or punched filters, and can reduce material waste to as low as 0.1%. It maintains constant pressure while enabling very fine filtration, supporting applications where material recovery and sustainabil- ity are priorities. BBE offers a wide range of melt filters, including the Cobra filter, which formed part of its display at K2025 and is said to set new standards in continuous polymer filtration. This high- performance system is

recycling which combines large-area, gentle melt filtration with precise IV control, ensuring consistently high melt quality. The modular system concept allows flexible adaptation to different material qualities and application areas, while the central component of the system is Visco+, an LSP unit for precise viscosity adjustment. Continuous adjustment results in a homogeneous melt with optimum processing properties, consid- ered ideal for end products in the fibre, film, or packaging sectors. Italian melt filtration specialist Fimic says it has developed the Forced Cleaning Scraper (FCS) to remove the most stubborn and adhesive contami- nations inside the scraper. A dedicated mechanical piston cleans the channels in seconds and dis- charges residues through the front valve, extend- ing the filter cloth’s lifespan and ensuring consist- ent machine performance. The company says the simple, and powerful solution is ideal for recyclers processing hard-to-clean materials who want to extend component lifespan, reduce downtime and manual intervention, and maximize operational efficiency and quality results. The first FCS was installed by


Fimic at Prezero. The company said in a LinkedIn post: “One of the main challenges was processing PP grade 50 contaminated with PET fibres, one of the most difficult materials for any filtration system. The FCS filter fully proved its effectiveness, ensuring continuity, quality and optimal management even of the most stubborn contami- nants, thanks to its automatic
