As early as 1903 Elmo was granted the Imperial Patent for the world’s first liquid ring vacuum pump; just three years later a smaller Elmo vacuum pump was used in Germany’s first vacuum cleaner. The first side channel blower was introduced in 1963 and revolutionized the vacuum and pressure market. The emphasis on designing and building the highest quality machines and providing engineering support of outstanding professionalism has been the trademark of Elmo. After the turn of the millenium and its spin-off from Siemens, Elmo merged with Nash Industries, a former US competitor, to form nash_elmo.
