Roots blowers consist of two identical and symmetrical rotors that have two or three meshing lobes inside an airtight case. The case is valveless and has inlet and outlet ports that are generally on opposite sides. The rotors counter-rotate and are synchronized using a set of gear wheels. Air is displaced from the inlet to the outlet by the motion of the meshing lobes on the counter-rotating rotors. The rate of airflow from the displacement is governed primarily by the rotational speed of the rotors within the roots blower. There is no change to air volume within the roots blower, so no air compression takes place. Roots blowers are generally air-cooled and some models operate without the need for oil as a lubricant (oil-free).
