ABSTRACT:
A multiround filter housing apparatus, cleaning system and method are provided. A filter housing having an integrated base that includes an integral cartridge plate, a plurality of cartridge filter bores, an inlet manifold and an outlet manifold is presented. The upper face of the integral cartridge plate is recessed to facilitate drainage of product and cleaning media. The lower portions of the cartridge filter bores are connected to the outlet port by additional sloped bores, thereby eliminating the need for a collection chamber. A spray device assembly is provided to facilitate a complete “Clean-in-Place” system in conjunction with the filter housing of the present invention.
