Donaldson Company, Inc.

We are a recognized pioneer in nanofiber technology.

For over two decades, we have manufactured and tested filter elements using fibers less than a micron in width.

In the transportation market, with tightening environmental regulations and improved aerodynamics necessitating decreasing sizes and weights, our R&D efforts have produced smaller, lighter and more efficient filters and filtration systems.

Our engineering, technology and operations staffs are continually developing innovative solutions to anticipate and exceed evolving requirements.

With over 1,600 active patents and industry-leading material and product design, our employees are vital to Donaldson's 100-year history of success.
