摘要： A filter element which includes an annular filter media is surrounded by an external wrap in the form of preformed metal coil instead of a standard metal sleeve. The preformed metal coil has end portions in the form of circular hoops which are retained by adhesive, which adhesive is used to both seal the ends of the filter media and to retain end caps in place on the filter media. The preformed metal coil is of specific use with filter elements that are cleaned by back pulsing in industrial facilities, but is used in any situation where standard metal external sleeves are now used for filter elements.
