ALMiG Turbo compressors

Reliable. Energy-Efficient. Oilfree.


  1. The ambient air passes through the inlet guide vane (IGV) into the first compressor stage.
  2. The first-stage impeller accelerates the air; the speed is converted to pressure.
  3. The compressed air, which is now hot, passes into the first intercooler.
  4. The cooled compressed air then reaches the pipeline for the second stage.
  5. The compression process is repeated in the second stage with renewed cooling in the second intercooler.
  6. After the intercooler, the compressed air reaches the third and last compressor stage. The clean oil-free compressed air passes into the compressed air system via the compressed air aftercooler.

100 % oil-free compressed air

The ALMiG compressors are certified in accordance with ISO 8573-1 Class 0 and provide 100% oil-free compressed air.
