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 internationalization – over the last 150 years we “Aerzeners” repeatedly took brave decisions to put us a step ahead of the competition.
Aerzener Maschinenfabrik is founded by the manufacturer and graduated businessman Wilhelm Meyer.
Since 1868, all the castings for machines made in Aerzen were produced in the factory’s own iron foundry.
From 1868 onwards the company produces the first positive displacement blowers produced on the European continent using the method developed by Francis Marion Roots – blowers that are far more efficient than conventional machines.
Wilhelm Meyer leaves the company and surrenders it to his younger brothers Sigmund and Emil.
The fabrication program includes Positive Displacement blowers, steam locomobiles, threshing machines, fodder chopping machines, hay makers, circular saws and portable forges.
The production of agricultural machines is stopped, the production of blowers increases. Supply of cupola melting furnaces, foundry machines, complete forging devices and brewery machines.
The connection of Aerzen to the rail network guarantees a further uptrend.The 5,000th positive displacement blower is manufactured and sent to Berlin by railway.
Conversion of the Aerzener Maschinenfabrik into an exempt private company. Hermann Allstaedt becomes Managing Director and first associate.
Aerzener Maschinenfabrik has innovations patented: the “modern dust removal system” (by means of a tube system an Aerzen positive displacement blwoer installed in the cellar removes the dust from curtains, carpets and furniture) and silencers for blowers.
The generation of rotary piston pumps is introduced on the market: The shape of the rotors is similar to the shape of the rotary pistons of the blowers. They distinguish themselves by symmetrical, two-lobe profiles, which enables them to convey thick as well as thin liquids.
In the difficult period of the world economic crisis in Aerzen the production of rotary piston gas meters starts, a decisive step on the path towards a special factory for positive displacement machines and thus out of the economic crisis.
The 20.000th blower is produced.
In the middle of the Second World War, in 1941, Karlheinrich Heller assumes the management of the company from his father-in-law, Hermann Allstaedt, and begins the development of the first screw compressors.
Screw compressors working according to the Lysholm-principle are produced. With initially oil-free handling with internal compression they achieve higher compression ratios than positive displacement blowers.
Shortly after the inauguration of a new production hall the 100,000th positive displacement blower leaves Aerzener Maschinenfabrik.
After the sudden death of Karlheinrich Heller in July 1960 Paul Grote takes over the management of the company for five years and leads Aerzener Maschinenfabrik through the 100th anniversary of the company.
Hasso Heller, only son of Anneliese and Karlheinrich Heller, becomes managing director.

“150 years” Aerzener Maschinenfabrik GmbH In our anniversary year,
we are presenting ourselves with this new philosophy:
Extension of Delta Screw series
The four compressors of the new series Delta Screw E compressor has been extended by AERZEN with two additional sizes now available. The new models VM 30 and VML 35 cover the lower volume flow range of the series and are the perfect addition to the Delta Screw compressor packages with belt drive. This new series of E compressor includes 6 sizes in the volume flow range from 330 m³/h to 7,000 m³/h
Market launch of the new and innovative AERsmart machine control system
The new superior machine control AERsmart optimally distributes the air volumes to the AERZEN technologies Blower, Hybrid and Turbo and their individual efficiencies.
Result: stand-alone efficiency values close to the theoretical optimum. Additional savings of up to 15%. Integration also of third-party products.
AERZEN develops an innovative modular system for large blowers
With the innovative “Alpha Blower” series of large blowers, AERZEN is now expanding its product range in the process air stages. With 104 model variants, the series offers a high degree of flexibility for numerous customer applications. Just always rightsized!
