Abstract
The invention includes a filter element (10) having a pair of end caps (12) with pleated, corrugated filter media (14) spanning therebetween. The filter media (14) is sealed or potted into the end caps (12) with a potting material ( b 16). To ensure substantially uniform penetration of the plates of the media (14) by the potting material (16), the edges of the media (14) are configued to eliminate "linear check valve" action between pleats. Several edge patterns can be used to minimize the formation of linear check valves, including a saw tooth pattern; sine wave pattern; vertical edge corrugations; flat edge regions; and saw kerfs in the edges of the media.
