History of Innovation

Nearly a Century of Experience.
Donaldson Company was founded in 1915 when Frank Donaldson Sr. developed a simple air cleaner to solve a farmer's tractor problems. In the late 1920s, crop fires caused by engine sparks fueled our diversification into exhaust products. Success and innovation in agricultural equipment led directly to opportunities in the construction and mining markets and later to the over-the-road truck market.
