5121-T-USA FILTER PLEAT SUPPORT MEANS ABSTRACT This invention comprehends a new and unique means for preventing the crowns (forward projections of the pleats) of a backflushable filter element from splitting due to the cyclic action that is experienced during cleaning and backflushing. In one embodiment, a plurality of spacers, preferably wedge shape, is positioned between the outwardly projecting pleats of the filter media thereby preventing the splitting thereof. A plurality of spacers may also be placed between the inwardly projecting pleats to provide additional support during the cleaning and backflushing cycle. In another embodiment a ring is placed adjacent the inwardly directed pleats and the inner end cap lip; this also prevents splitting of the crowns when the filter element is subjected to the cyclic action of cleaning and backflushing.
