The article discusses the applications of Roots type supercharger, also known as Roots blower, which was named after Philander Higley and Francis Marion Roots of Connersville, Indiana. Gottlieb Daimier included the use of a Roots-style supercharger in a patented engine design in 1900. It examines the technical aspects of a Roots blower, and mentions that its high pumping speed can be used to lessen the end pressure and increase the pumping speed of other vacuum pump systems in the medium to low vacuum range.
