Blowers constitute the air movers in many pneumatic conveying systems running lean phase. They can be placed at the beginning of the line, delivering an overpressure, or at the end of the line to produce a vacuum. The most common type of blower used for this purpose is the Roots blower, a volumetric blower (positive displacement) that can be operated either in pressure or vacuum without specific changes.
