VARIO
The VARIO mode is based on the DUAL control mode. The difference to DUAL is that the
idling
time is automatically lengthened or shortened to compensate for higher or lower machine starting
frequencies.
MODULATING control
The MODULATING control is an additional mechanical regulation. It continuously changes the flow
rate within the machine's control range.
A control valve, the proportional controller, changes the degree of opening of the inlet valve when
the machine transports compressed air into the air network (LOAD)
The load and power consumption of the drive motor rises and falls with the air demand.
