Tradition and innovation

From a construction plumber to a global leader in air filtration technology
Almost 110 years ago, Keller Lufttechnik started in the plumbing business. The company was founded by Albert Keller in Stuttgart-Uhlbach in 1903. Following the complete destruction of the factory in World War II, his son Otto Keller opened a factory for air pollution control and thermal process technology in Kirchheim unter Teck, in the foothills of the Swabian Jura. In 1952, Heinz-Dieter Keller assumed the reins of the company and established Keller Lufttechnik’s current range of products. In 1992, the next generation took over. The tradition of the family-owned company is now carried on by Horst and Frank Keller.
Today, Keller Lufttechnik is a global leader in air filtration technology.
