Users can choose between constant speed mode or pressure control mode, making the vacuum pump exceptionally energy-efficient.

1/ Constant speed mode
For processes with constant vacuum demand, it is recommended to leave the PLUS vacuum pump running at constant speed.
2/ Pressure control mode
For processes with changing vacuum demand over time, the pressure control mode is the ideal choice. In this case the PLUS vacuum pump adjusts the rotational speed according to the required vacuum level.
Once this vacuum level has been achieved, the PLUS vacuum pump continues to run at minimum speed, enabling it to respond to a sudden need for increased vacuum demand and leading to further energy savings.
