Experience in the production of twin shaft rotary lobe machines has a long tradition in Aerzen. Founded in 1864 Aerzen produced Europe's very first rotary piston machine in 1868. The manufacture of rotary piston gas meters began in 1930, followed by the introduction of the first rotary screw compressor in 1943. The worldwide Aerzen sales- and service organisation enjoys high reputation. Positive displacement blowers for conveyance of air and neutral gases with intake volume flow of 30-100.000 m³/h, overpressure up to 1000 mbar, low pressure up to -500 mbar, depending on blower size. Screw compressors, oilfree and oilinjected, for compression of air and gases with intake volume flows of 70-120.000 m³/h, pressure operating up to pe=13 bar single stage, up to pe=40 bar multi stage, depending on compressor size. Rotary piston gas meters for gas volume flow measurement from 0,65-6.500 m³/h, measuring pressure up to 25 bar.

Aerzen拥有制造双轴容积式机械的悠久传统。成立于1864年的Aerzen，于1868年制造了欧洲第一台罗茨风机。罗茨式气体流量计的生产始于1930年，紧接着在1943年，Aerzen制造了第一台螺杆空压机。Aerzen遍布全世界的销售及售后服务网络享有极高的声誉。罗茨风机主要用于空气或中性气体的输送，进气流量30-100000立方/小时，正压达1000mbar，负压可达-500mbar，取决于不同机型。螺杆压缩机，无油和喷油两种，用于空气或特殊气体的压缩，进气流量70-120000立方/小时，正压单级可达13bar，多级可达40bar，取决于不同机型。罗茨式流量计，计量范围0.65-6500立方/小时，压力可达25bar。
