Underpressure for suction in the vacuum dust cleaning systems is created by Roots vacuum pump. High underpressure created by it allows providing necessary airflow in flexible hoses and pipelines. Working principle of Roots compressor is in rotation of two identical rotors with flaps in compressing surface, working as a rotating piston. When rotating, they capture the incoming flow of gas from the suction inlet, gradually isolate it in openings between flaps and body, compress and move it towards pressurizing pipe, pushing through the outlet opening.
