Donaldson develops nanofiber products and nanofiber filter media for applications where sub-micron fiber diameters, high filtration efficiency, high surface area and other unique material properties are useful. For many years, Donaldson has used its patented and patent-pending nanofiber filter media in Ultra-Web® filters for dust collection, Spider-Web® filters for gas turbine air filtration, and Donaldson EnduranceTM air filters for heavy-duty engines.

Now, our proprietary nanofiber technology is available for new applications so customers in other markets can also benefit from the technology.
