ABSTRACT:
An improved filter apparatus including a securing mechanism to hold a flexible filter media such as a filter bag in position. The securing mechanism includes a receiving member having an internal bore adapted to receive a portion of the filter media. A retaining ring having an externally projecting contact ridge adapted to make essentially line contact around the inner periphery of the receiving member is utilized to secure the bag within the receiving member. The filter cloth may either be inserted between the securing ring and the inner surface of the receiving member, or a slightly larger securing ring may be utilized to seat on top of a conventional filter bag retaining ring to secure the ring and the bag in position.
