Aerzen
About
Aerzener Maschinenfabrik GmbH (Aerzen), founded in 1864 and headquartered in Aerzen, Germany, is one of the world's oldest and largest manufacturers of gas handling equipment, with approximately 2,500 employees across over 50 subsidiaries in 100+ countries. The company engineers the full spectrum of air and gas conveyance technology: positive displacement rotary lobe blowers (Delta Blower Generation 5), screw blowers that merge blower and compressor principles (Delta Hybrid series), high-speed turbo blowers (Turbo G5/G5+/G6), and screw compressors (SW water-injected, SI oil-injected, DS oil-free). For wastewater aeration, Aerzen offers the integrated AWTS package combining blowers, fine-bubble diffusers, and intelligent controls—coordinated by AERsmart master control and monitored through AERZEN WebView and AERprogress cloud analytics. The Performance3 concept stages turbo, hybrid, and PD units for optimal energy efficiency across varying demand.
