Individual filtration solutions for difficult dust removal tasks The most efficient possible separation of problematic or harmful dusts in industrial production protects people and systems while optimizing work processes. Low emissions protect the environment. In the recovery of powdered products or dusts in silos, the focus lies on maximum efficiency and the highest possible operational dependability. Home World of Industrial Air Pollution Control SolutionsFilter mediaRelevant norms and standardsCompetence areasViledon Filter ServicesProducts Maximum efficiency for your dust removal system The selection of suitable filters in combination with the system parameters is critical for the efficient operation of a dust removal system. Several aspects are decisive here for the operator: economical operation, meaning complying with or – even better – reducing operating costs, and an improved energy balance. Extended filtration cycles and cleaning intervals for the filter elements used therefore have a major impact. They can minimize costs for maintenance and replacement over time while contributing to compressed air cost savings. The right solution for each and every requirement Filter products from Freudenberg do an outstanding job in countless applications that call for dust removal or emission protection. They not only provide top performance in their area, they also achieve a long service life while saving additional space and money, depending on the application. The analysis of the process requirements, including the nature of the dust arising there, is a major success factor in our concepts. After an analysis of the current situation, we individually select the suitable filter medium and the right dust removal element, which can vary in shape, nominal diameter and pleat geometry. We also provide support on technical aspects of the system design. In our laboratories, we put dust under the microscope and conduct damage analyses. In this way, we develop solutions that can overcome even the most difficult dust removal problem. For you as a user, first class dust removal with Viledon filters means The filter medium matters Minimize maintenance work, lower operating costs. Specially developed for the diverse requirements of dust removal and emission protection, high-performance filter media provide unique properties for optimal air purity at your plant. Our patented production processes guarantee consistently high product quality. sinTexx Plus Corrugated polyester filter media with nanofiber layer achieve optimum values for removing dust from fine smoke produced in welding, cutting and coating processes as well as for particularly difficult-to-handle dusts. Compared with the performance of conventional polyester media or ePTFE membrane media, filter cartridges with sinTexx Plus have clear advantages and will improve the energy balance of your systems. Further information NEXX of Evolon® The sustainable media alternative, used in Viledon filter bags. For lastingly low emissions and reduced energy costs, plus 50% lower resource consumption during production. Viledon NEXX media offer outstanding properties compared with typical needled felt media: 50% lighter than needled felt, making it easier to handle for cleaning and installation. With original Evolon technology. Further information Learn more Antistatic filter media For use in both filter cartridges and filter bags, Freudenberg offers a number of nonwoven media that are equipped with patented pattern printing applied on both sides via carbon suspension. This makes them suitable for separation of explosive dusts while also offering high operational dependability and lasting antistatic properties, even in the face of abrasive dusts. Further information Robust filter media for suction excavators The selection of filter media also includes special variants optimized for specific applications, such as for suction excavators or cleaning vehicles. Here the filter medium must withstand the highest requirements: high mechanical robustness and tear resistance, no blocking of the pores by mixtures of dust with moisture, easy cleaning. Contact us Viledon dust removal filters stand up to the strictest monitoring Relevant norms and standards Viledon filter elements for dust removal and emission protection are subjected to the strictest internal and external quality controls. External inspections include IFA (DIN EN 60335-2-69) tests, which focus on the arrestance of harmful dusts with an eye toward work safety and health protection Our antistatic filter media are tested by DEKRA EXAM for explosion protection, and we can present certificates documenting the electrical surface resistance and volume resistance < 10⁸ ohms. For use in the food industry, our dust removal media are inspected for food safety according to the requirements of diverse ordinances. This includes the Food and Feed Act (LFGB), EC and EU regulations concerning materials and equipment that comes into contact with food as well as ISO 846:1997, which regulates the impact of microorganisms on plastics. We would be happy to present the corresponding test certificates Contact us Learn more Benefit from our specialized expertise in industrial dust removal. Select and request detailed information.

Many of these are toxic or explosive and are harmful to people and the environment. As a longstanding partner to industry, we are ideally informed of the specific industry requirements and production processes and can ensure the protection of your processes and employees with a dust removal solution customized for your situation. Steel / metal / foundries In the steel and metalworking industry, Viledon dust removal elements are used in a wide range of process steps, contributing to lasting compliance with statutory emission limits. For extraction of scale, flame-cutting dust and laser-cutting smoke, sinTexx Plus filter cartridges are choice number one thanks to their media advantages. In extraction from transferring processes as well as hot and cold rolling mills, for continuous casting and slabbing mills or even foundry sand recycling and cleaning processes, NEXX filter bags exhibit consistently high performance and low emissions. Learn more Wood processing and woodworking In the wood processing industry, dust and chips must be extracted to provide clean, dust-free air at the workplace. Wood dust can cause impairments of the respiratory tract and skin or even allergic reactions. Hardwood dust is even classified as carcinogenic to humans. In addition, wood dust is combustible and explosive in that it can ignite in one location and trigger a chain reaction that results in a complete explosion of the entire dust and chip mixture. Viledon filter cartridges and filter bags with BGIA-certified filter media contribute to effective extraction at machines, systems and workstations and impress with very high abrasion resistance and long lifetimes. Learn more Chemical industry / pigments Viledon NEXX filter bags are used successfully in the separation of inorganic paint pigment dust. To achieve the best painting results, the pigment industry aims to manufacture pigments with the smallest possible particle diameters. This type of dust does not form a suitable dust cake for surface filtration. The filter medium must therefore offer a finely porous and fibrous surface. Viledon NEXX bags satisfy this requirement and are also produced without silicone, meaning they are also suited for product recovery of powder coating pigments used in the automotive industry. Further information Cement industry Very high dust emissions result from the production of cement. The main emission sources for this are preparation of the raw materials and fuels, the clinkering process and the cement grinding. With the technologies currently available, emissions below 20 mg/m³ are possible, in modern plants even below 5 mg/m³. To comply with the environmental standards, the filter systems are generally equipped with bag filters. The lightweight Viledon NEXX filter bags of composite materials offer tremendous advantages in this application compared with needled felts with support fabrics and high weights per unit area. They are stable and can handle stress, they last significantly longer and reduce the energy costs for the user.
