Expertise in blower and compressor technology since 1864
Aerzener Maschinenfabrik GmbH (AERZEN) has been developing and manufacturing machines for conveying and compressing gases and air since 1864. The product range includes rotary lobe blowers (Positive Displacement Blowers), screw compressors (oil-lubricated and oil-free), screw blowers (Screw Blower), oil-free high-speed turbo blowers as well as process gas blowers, compressors and gas boosters, onshore and offshore, in machine or container design. The portfolio is complemented by control and monitoring technology (AERtronic, AERsmart, AERprogress, Webview), engineering services such as process sizing, FEM and acoustic calculations, HAZOP studies as well as retrofit with 3D laser scanning, plus service, rental of oil-free units and machine diagnostics. Customers come from industries such as wastewater/water treatment, chemicals and petrochemicals, oil and gas, energy, steel, cement, biogas, refrigeration technology and pneumatic conveying. The headquarters with production is located in Aerzen near Hameln (Lower Saxony), with further locations in Germany and more than 50 subsidiaries worldwide. The group generates annual revenue of around €664 million with an export share of approximately 83%.
