AERZEN looks back on an eventful history. Whether Wilhelm Meyer, who was the first on the continent to have positive displacement blowers made using the Roots method, Hermann Allstaedt, the Managing Director during the 1930s who focused production consistently on blowers, pumps and gas meters,or Hasso Heller, who founded the first subsidiary Aerzen France in 1968 to set the company on course for internationalisation – over the last 150years we “Aerzeners” repeatedly took brave decisionsto put us a step ahead of the competition.
