Donaldson Company, Inc.

As a global leader in the filtration industry, we pride ourselves on our innovative technologies and solutions, backed by a talented and dedicated team of employees. In 1915, a young Frank Donaldson Sr.—then a Bull Tractor Company salesman—visited a customer whose tractor kept breaking down in his dusty field. Frank hand-fashioned a simple air cleaner to protect the engine and invented the world’s first effective air cleaner for a tractor engine. Over 100 years later, Donaldson continues to innovate, using our filtration technologies and processes to provide customers with the solutions they need. Donaldson works with our customers to solve some of the world`s most complex filtration and contamination control challenges, and we are now one of the largest providers of unique filtration technologies and high-quality filters and parts in the world.
