Fig. 8.9: BOGE screw compressor

The ideal usage rate UR of a screw compressors is 100 %. This means, the required FAD L_B is equal to the minimum output

_min of the compressor.

The choice is:

Screw compressor, Type S21

Maximum pressure p_max : 8 bar

FAD

: 2,42 m³/min

Motor output rate: 15 kW Þ Al = 25
