The GAVSD compressors optimise the power consumption and reduce the operating pressure band by matching the motor speed to the air net pressure.
The regulator will continuously vary the motor speed, thus maintaining the net pressure as close as possible to the programmed set point. The pressure fluctuations will then be very low.
There is no setting of load/unload pressure, only programmed set point.
The motor will stop and start in accordance with the air demand. The speed varies according to the net pressure:
If the net pressure is higher, the speed is decreased.
If the net pressure is lower, the speed is increased
