Eaton designs and manufactures precision Roots-type positive displacement superchargers for highly specific automotive applications. The Roots-type design was first patented in 1860 by brothers Philander and Francis Roots and refined for automotive passenger car use by Eaton and commercialized in the 1980s. To date we have produced more than 3 million Roots superchargers for our global customers.
Our customers use our Roots superchargers to add power to their engines and create a tailored driving experience. Unlike turbocharging, Eaton superchargers provide instant throttle response and torque across the engine's entire powerband. Although supercharging is most associated with high performance and drag racing, Eaton Roots-type superchargers are also used by our customers to improve fuel efficiency because they provide the option of using smaller, more fuel efficient engines to achieve desired driving characteristics.
