ABSTRACT:
An apparatus and method for filtering a fluid containing contaminants is provided whereby the apparatus includes an inlet for drawing fluid from a fluid source, a housing having attached thereto the inlet, a contaminant outlet, a clean outlet, a filtering assembly and a mechanism for agitating the filtering assembly. The filtering assembly has an upper or upstream end connected to the inlet and a lower or downstream end connected to the contaminant outlet. The filtering assembly is disposed within the housing and is connected to the contaminant outlet whereby fluid is introduced to the filter assembly at an upper end of the filtering assembly by the fluid inlet and whereby fluid is passed through the filtering assembly to provide clean, filtered fluid which is discharged via the clean outlet, and debris and other contaminants contained in the fluid are separated from the fluid and retained by the filtering assembly. The debris and other contaminants that are retained by the filtering assembly are discharged via a lower or downstream end of the filtering assembly, and through the contaminant outlet. The agitating mechanism agitates the filtering assembly to move the filtering assembly through the clean, filtered fluid to independently remove the debris and contaminants that have been retained by the filtering assembly.
