Spacers are located between each pair of adjacent filter elements, and each spacer includes a ring portion which surrounds the shaft and spaces the adjacent filter elements from one another, and a plurality of spoke portions which extend outwardly from the ring portion and of which each has an upper edge engaging a downwardly facing side of the plate member of the upper filter element of the pair, and a lower edge engaging the filter cloth on the lower filter element of the pair, in order to hold the filter cloth against the associated plate member.
