Root Blower
Roots compressor or blower has two rotor which each have two teeth (Lobe) and the shape is similar to the pockets. The two rotor spinning simultaneously in the opposite direction inside a house. The axis of the rotor is always perpendicular to each other. How it works is as follows. When both rotor are rotated, the two lobes of the tooth will rotate, when the rotation starts in the vacuum suction area, so air enters the space between the tooth lobes with the right or left blower wall, alternating. As the air gets pushed into the narrower space, its pressure rises, and the expenditure area is expelled.
