ABSTRACT:
An automatic drum filter comprises a perforated drum having a continuous filter media wrapped around substantially the entire periphery thereof. A supply roll of the media and a reroll drum are supported for rotation about an axis substantially parallel to the axis of the drum. A variable speed motor drives only the reroll drum. A pair of endless chains extend around each end of the drum so as to preclude axial displacement of the media on the drum.
