Abstract
A dual suction unit and method of operation uses a main tube with a Venturi assembly having a primary suction inlet positioned in the inlet of the main tube and a branch tube joined at its outlet to the mid-portion of the main tube and having a secondary suction inlet at its opposite end. Compressed air flowing through the Venturi assembly induces a primary suction at its suction inlet and a significantly stronger secondary suction at the inlet of the branch tube than known in the prior art. Waste or other matter may be conveyed from separate sources to the respective primary and secondary suction inlets.
