Abstract
A rotary agitator for use in filter systems has a horizontal arm formed of a single, elongate, hollow tubular section. An opening through the peripheral wall of the tubular section at substantially the midpoint thereof communicates with the hollow interior of the tubular section. An external rotor section of a central bearing assembly is secured directly to the hollow tubular section in a region overlying the opening through the peripheral wall of the tubular section. The external rotor section has a passageway therethrough communicating with the opening through the peripheral wall of the tubular section. The central bearing assembly further includes an elongate stator positioned interiorly of the external rotor section. The passage through the elongate stator is aligned with and in communication with the opening through the peripheral wall of the tubular section.
