Three-blade rotary lobe blowers work according to the proven Roots system: two parallel rotary pistons mounted rotate in opposite directions within a housing. The pumped medium is sealed in the space between the rotors and housing. It is compressed, pumped through the housing to the gas discharge by the rotary motion and discharged. A silencer with integrated inlet filter is connected upstream of the blower stage. Once the medium has been compressed during the blower stage, it flows through the downstream discharge silencer. The drive unit is operating with a motor using a v-belt. The v-belt drive enables the blower speed to be precisely adjusted to the process.
The design of the rotary lobe blower is practically identical in the vacuum and overpressure version.
