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.
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.
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.
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.
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.
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.
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.
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.
Problematic dusts arise throughout a wide range of industrial processes. 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.
