Abstract

A rotary fluid filter including a filter body rotationally mounted within a housing. The housing having a front cap having a main fluid inlet and a backwash outlet, a rear cap having a main fluid outlet and a backwash inlet. The filter body having a front face, a rear face, and a plurality of fluid flow passages each extending through the filter body between the front face and the rear face and having a filter received in each fluid flow passage. The filter body operable to rotate with in the housing such that, for each fluid flow passage, as it is aligned with the main fluid inlet a main fluid is received therein, as it is aligned with the main fluid outlet the main fluid is discharged therefrom, and as it is aligned with the backwash inlet and the backwash outlet a backwash fluid is received therethrough.
