CA 2161851
In prior pressure washer drums, the filter deck was supported on the central shaft by spokes welded to the central hub which was in turn welded to the shaft. The extreme forces caused premature failure of the welded joints. The present invention provides a pressure washer drum in which sandwic- hed parallel plates having an array of apertures replace the spokes and central pipe and journals are supported on the hub by a bolting system rather than by welding.
