Technology Leadership

A Record of Innovation and Industry Firsts

We are a recognized pioneer in fine fiber 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. 


Talented and Experienced Colleagues

Our engineering, technology and operations staffs are continually developing innovative solutions to anticipate and exceed evolving requirements. With over 1,800 active patents and industry-leading material and product design, our employees are vital to Donaldson's 100-year history of success.
