Donaldson Company, Inc. is a leading worldwide provider of filtration systems and replacement parts. Since 1915, we have perfected and leveraged our innovative technology, strong customer relationships and broad geographic presence to meet the diverse and changing needs of our customers.

Donaldson creates a broad spectrum of filtration products and services to meet the evolving needs of our diverse customers. These filtration solutions span the entire life cycle of a customer’s application, from initial system design through replacement products.

Donaldson has a long tradition of innovation. We invented the world standard for advanced nanofiber air filtration technology–Ultra-Web®. Donaldson began research into the chemistry and production of fibers less than a micron in diameter before they were even called nanofibers. Our first commercial application came in 1981. Ultra-Web enables longer service intervals to reduce operating costs and high efficiency for better equipment protection. Today, this innovative technology is backed by over 80 issued and pending patents, and has benefited numerous industries including dust collection, transportation, construction, agriculture, mining, military and gas turbine.
