A combined unloader, also called a pressure regulator, holds the system at its working pressure by unloading the compressor once the cut-out figure is reached and loading it again when pressure drops to the cut-in figure. Units are selected by cut-out pressure; this group runs from 7.3 bar to 9.5 bar.
