In 1915, a young Frank Donaldson Sr.—then a salesman for the Bull Tractor Company—visited a customer whose tractor kept breaking down in his dusty field. Frank hand-crafted a simple air cleaner to protect the engine, inventing the world’s first effective air cleaner for a tractor engine.
Realizing the value of his idea, the young salesman-turned-inventor introduced his air purifier to the market, and the Donaldson Company was born.
Over 100 years later, Donaldson continues to innovate by using our filtration technologies and processes to provide customers with the solutions they need.
