History

Close

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. 

Understanding the value in his idea, the young salesman-turned-inventor introduced his air cleaner to the market, and Donaldson Company was born.

Over 100 years later, Donaldson continues to innovate, using our filtration technologies and processes to provide customers with the solutions they need.
