ABSTRACT:
A filter comprising a center tube and a porous metal filter pack surrounding the center tube. The filter pack has a plurality of pleats extending longitudinally of the center tube with each of the plates having first and second ends. A metal-to-metal bond seals the first and second ends of the pleats closed. An additional metal-to-metal bond attaches the filter pack to the center tube and seals the filter pack to the center tube. The conventional filter end caps are eliminated to reduce entrapment of debris at the ends of the filter pack and to facilitate cleaning of the filter.
