A tri-lobe blower is a positive displacement blower that generates the airflow required to create vacuum suction. As the three-lobed rotors rotate, they move a constant volume of air through the system, producing reliable vacuum performance without requiring priming.
Because they deliver continuous airflow at relatively low operating speeds, tri-lobe blowers are widely used in vacuum excavators and hydrovacs where reliability and durability are essential. No Dig Equipment uses positive displacement tri-lobe blowers throughout its VM range of vacuum excavators
