MANN-FILTER has introduced commercial vehicle air filters featuring an in-house developed and manufactured nanofiber filter media designed to improve filtration efficiency and extend service intervals. The technology is being used in selected air filters for Mercedes-Benz Actros II and DAF XF 105, XF 106 and XG-generation trucks.
The nanofiber media consists of a cellulose base coated with ultra-fine polymer fibers measuring approximately 0.13–0.15 micrometers in diameter. According to the company, the finer fiber structure increases the filter surface area, enabling higher dust holding capacity while maintaining low airflow resistance.
MANN+HUMMEL states that the nanofiber media achieves a particle separation efficiency of up to 99.98 per cent, compared with around 40 per cent for the base material alone for particles of the same size. The company says the technology captures contaminants on the filter surface, reducing pore blockage in the base material and supporting longer service intervals. “The ultra-fine nanofiber layer in our filters is the result of the expertise of nearly 1,100 researchers and developers worldwide who are constantly working on innovative technologies. The result is an exclusive filter medium that is available only to MANN+HUMMEL, no other filter manufacturer has access to it. This allows us to provide our customers with filtration performance that stands out on the market thanks to its combination of nanofiber technology, service life and flow rates,” Jörg Schömmel explains as Senior Range Manager IAM at MANN+HUMMEL.
The filter media is also designed to meet commercial vehicle operating requirements, including flame-retardant properties and water stability. MANN+HUMMEL develops and manufactures the nanofiber media in-house and says the technology is exclusive to its filtration products.
