Small startingcurrent, more energy-conserving.
FCS is the bestcontrol system for the user who require the constant flow rate.
If compressor supply > use → pressure of air tank rise
If compressor supply = use → pressure of air tank invariable
FCS control thepressure in the pipeline, the frequency converter compare the pressure whichfrom pressure sensor pick up from air tank with the setting pressure, andaccording the difference control the motor rotational speed, then keep thecompressor working pressure with the setting pressure.
