Abstract
A conically shaped filtration and/or separation apparatus is provided which is constructed from a stack of filters at least some of which are different sizes superposed above each, other, of said plurality of said filters in a fluid communicable relationship. A collapsible version of such conically shaped filter and/or separation apparatus is provided whereby a plurality of such filters are connected together using two piece interlocking or connecting end caps.
Claims18
A stacked, conically shaped filter element including an uppermost tubular filter having an uppermost end cap, and a lowermost tubular filter having a lowermost end cap, said uppermost tubular filter and said lowermost tubular filter separated by at least one intermediate tubular filter, said uppermost tubular filter, said at least one intermediate filter and said lowermost tubular filter superimposed above each other, in order of decreasing diameter, in a fluid communicable relationship, wherein each of said at least one intermediate tubular filters has an upper and a lower end cap, the inner diameter of each of said intermediate tubular filters being less than the inner diameter of an adjacent lower tubular filter, and the outer diameter of each of said intermediate tubular filters being less than the outer diameter of said adjacent lower tubular filter, but greater than the inner diameter of said adjacent lower tubular filter, thereby forming a conically shaped filter element from a plurality of tubular filter elements of differing diameters superimposed one above the other.
