About Us

Over 85 Years of Onan Quality

Established by D.W. (David) Onan in 1920, Onan has been a leader and pioneer in power generation equipment for more than 80 years and engines for 50 years. A lot of years have passed and a lot has changed since the first Onan generator sets entered the market - the products, technology, marketplace and of course, the company. In 1986, Onan Corporation became a fully owned subsidiary of the Cummins Engine Company (now Cummins Inc.), the world's largest designer and manufacturer of diesel engines ranging from 55 to 2,700 horsepower for on-highway vehicles, industrial equipment, and power generation. During our history, the Onan branded product lines have expanded, while still being known as solid, innovative and hard working.

World Leader in Power Generation

Today Onan branded products are built by Cummins Power Generation, a subsidiary of Cummins Inc. and a world leader in the design and manufacture of power generation products and services.

Onan branded products are used in recreational vehicle, marine, commercial mobile, and residential standby applications.
