ABSTRACT:
A spray cleaning apparatus for tubular filter elements, comprises a spray chamber in which a filter element is mounted between opposed rotary turntable discs. The chamber is provided with liquid sprays for spraying both the inner and outer surfaces of the element as it is rotated by the turntable. The sprays are reciprocated vertically so as to traverse the height of the filter element. Particular features of the invention reside in the turntable construction; a control system for accurately reversing the up-and-down movement of the sprays dependent on the height of a filter being cleaned; and a particular form of spray nozzle structure useful for cleaning pleated filter elements.
