Donaldson

Donaldson was formed in 1915, when Frank Donaldson, Sr. invented the first effective air cleaner for a tractor engine. The company opened its first international location in Canada in 1945 and in the 1950s introduced Donaclone dry-type air cleaners with a replaceable paper filter, which started its aftermarket business.

Donaldson Company, Inc. has its global headquarters in Bloomington, Minnesota. The company reports 3.9 billion US dollars in revenue, more than 150 facilities, locations in over 40 countries, more than 100 technical laboratories and over 2,800 active patents.
