Compressor and blower technology since 1864
Aerzener Maschinenfabrik GmbH, headquartered in Aerzen (Lower Saxony), was founded in 1864 and has been producing blowers since 1868. The company manufactures and develops oil-free rotary lobe blowers (GR, GQ series), screw compressors (VRA, VMY series), turbo compressors (CC-Type), gas boosters (GMD, GM-HP) as well as turbo blowers for air, process gases, aggressive and neutral gases – from vacuum to 10 bar and volume flows up to 350,000 m³/h. The portfolio is complemented by control technology (AERtronic, AERsmart, AERprocess, Webview), engineering and project management including HAZOP, FEM analysis and acoustic calculations, 3D laser scanning, and ATEX solutions for explosion-hazardous areas of zones 0–22. Through the AERZEN Rental Solutions division, oil-free blowers and screw compressors are rented out (approx. 150 units, depots in Europe and North America), complemented by a 24/7 emergency service, field service, machine diagnostics and vibration measurement according to VDI 3836 as well as condition monitoring (DRTM). Key industries are water and wastewater treatment, chemicals and process technology, petrochemicals, oil and gas, compressed air technology, iron and steel, cement, biogas, marine and energy technology. With around 2,600 employees, revenue of approx. €664 million (AERZEN Group), more than 50 subsidiaries and an export share of approx. 83%, the company serves customers in over 100 countries.
