Abstract
An aerator mixing rod includes a body having a first and second opposite ends and an outer surface extending between the ends. The body defines a longitudinal axis extending through the ends. The aerator mixing rod also includes teeth extending radially outward from the outer surface, with a first row of teeth and a second row of teeth spaced from the first row along the longitudinal axis. A first passageway is formed between adjacent teeth of the first row, and a second passageway is formed between adjacent teeth of the second row. The first passageway is at least partially misaligned with the second passageway in a direction parallel to the longitudinal axis such that the first passageway and the second passageway form a tortuous path for fluid flowing along the outer surface of the body. The aerator mixing rod is formed from an injection-moldable material by an injection molding process.
