Oil-free multi-stage screw compressor units

Screw compressors

Specially designed for oil-free air compressors

Compressed-air technology with system

The multi-stage screw compressor units from AERZEN are designed for oil-free compression of air and neutral gases and finds special application in the industrial compressed air production. The two-stage units cover drive capacities of 90 kW up to 900 kW and differential pressures from up to 10.5 bar. This corresponds to conveying performances from 500 to 8.000 m³/h. AERZEN is able to offer the most efficient solution for each case of application. Also the design of the entire unit refers to the sepecific customer requirements.

Besides the fulfilment of individual technical requirements (such as ATEX, sound enclosure, vibration monitoring, documentation) it also refers to the use of your works-standardized components and systems. On one hand this increases the operating safety (application of works-known components and systems) and on the other hand it decreases your operating costs (storage of spare parts, uniform training of staff members).

  • Decrease of your process costs
  • Uniform machine structure/ ETL - costs
  • Energy efficiency by optimum adjustment
  • Robust and reliable unit: Operational reliability
