Rotary Lobe Blowers


A rotary lobe blower is a type of positive displacement blower that utilizes two parallel rotary pistons mounted within a housing that rotate in opposite directions. 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 operated with a motor using a v-belt. The v-belt drive enables the blower speed to be precisely adjusted to the process requirements.

As stated, rotary lobe blowers are used in a variety of applications and industries making them a desired investment to improve processes and cut lead times. Listed below are some common applications of positive displacement blowers:
