3.1 How the compressor works
Compression process
BOGE scroll compressors are oil-free, stationary, electrically powered air com-
pressors. A scroll compressor functions according to the positive displacement
principle. It consists of two spirals; the moving spiral continuously compresses
the drawn-in air against the fixed spiral using an eccentric motion. The spirals
thereby form several increasingly narrower chambers within the coils. The gas
being pumped is sucked in from outside, compressed within the pump and
emitted via a connection in the centre of the spiral. This provides a constant,
oil-free flow of compressed air of up to 10 bar overpressure.
