2.2 Function description compressor

The air end operates according to the displacement principle. In the housing,
the main and secondary screws are driven by means of an electric motor and
V-belts.
Both screws have screw-shaped profiles, intermeshing without contact. To-
gether with the housing wall, these screws form chambers which gradually
reduce in size, seen in air flow direction.
