Usually, the only time the vacuum pump is utilized is for the “drying” of the cart or the gas compartment of equipment that is to be refilled with SF 6.

Vacuum Pumps – Wisconsin Energy Efficiency and Renewable Energy

Vacuum Pumps – The installation of a Variable Speed Drive (VSD), sometimes called a variable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better regulation of vacuum. The range of energy savings can be from 30 to 80 percent. They can be adapted to blower or in some cases rotary vane type vacuum pumps. They work by changing the speed of the vacuum pump based on the reading from a pressure sensor that is mounted on the vacuum line near the receiver jar.
