If the air demand drops below the minimum FAD, the net pressure will continue to rise until the
unload pressure is reached and the Elektronikon will unload the compressor as on a standard
compressor. With a continuing air demand, the net pressure will then drop, until the load pressure
is reached and the Elektronikon will let the compressor run loaded.
