Compressor element operating principle
Each compressor element consists of a fixed scroll shaped housing and a scroll shaped rotor. Air
enters the compressor element through inlet opening (1). Once the air is drawn in, the orbiting
scroll (4) seals the inlet opening and forces the air into a continuously decreasing space. As scroll
(4) keeps orbiting, this process of compression is constantly repeated, resulting in discharging of
oil free compressed air through outlet opening (3).
