Frank Donaldson Sr.

Frank Donaldson Sr.

In 1915, a young Frank Donaldson Sr., then a Bull Tractor Company salesman, visited a customer whose farm tractor kept breaking down in his dusty field. So he fashioned an air cleaner to protect the engine from the dust. The invention – the world’s first effective air cleaner for a tractor engine – worked, and Donaldson Company was born.

International Presence

The company began in a Minnesota metal shop with Frank, his father, W.H.L., and his brother Bob. The three hammered out Frank’s invention. One hundred years later, Donaldson holds over 1,600 active U.S. and international patents, and employees in 44 countries support customers around the world.

The Innovation of Filtration

For over two decades, Donaldson has been a pioneer in nanofiber technology, manufacturing and testing filter elements using fibers less than a micron in width. In the tightly regulated transportation market, our R&D efforts have produced smaller, lighter and more efficient filters and filtration systems. And our technologies help protect critical applications from the damaging effects of particles, gases and humidity in everything from computers to hearing aids. As equipment and technology advances, Donaldson continues to develop innovative solutions to anticipate and exceed evolving requirements.
