Abstract
A filter media is formed into a filter bag for fluid filter elements. A long tube of filter media is formed into a helix or a pleated structure with a corrugated cross-section to increase the surface area of filter media area that can fit into a given volume. A retaining structure can be used to maintain the shape of the filter media.
Claims20
A filter for use for separating constituent components of a fluid mixture, said filter comprising:
- a porous media material for filtration of fluids, wherein the porous material has a helically pleated shape comprising a corrugated cross-section;
- and
- the filter defining an axial length along the largest dimension of the filter;
- wherein
- the corrugated cross-section extends a substantial portion of the axial length of the filter.
A filter for use for separating constituent components of a fluid mixture, said filter comprising:
- a porous media material for filtration of fluids, wherein the porous material has a radially pleated shape comprising a corrugated cross-section;
- and
- the filter defining an axial length along the largest dimension of the filter;
- wherein
- the corrugated cross-section extends a substantial portion of the axial length of the filter.
A filter for use for separating constituent components of a fluid mixture, said filter comprising:
- a porous media material for filtration of fluids, wherein the porous material has a helically pleated shape comprising a corrugated cross-section;
- and
- a closed end at one end of the filter media;
- and
- an open end at the end of the filter media opposite the closed end to allow fluid to enter the filter
- at least one integral support structure which is positioned so as to maintain the helical corrugated shape;
- and
- a retaining strap that extends substantially the axial length of the filter;
- wherein
- the filter defining an axial length along the largest dimension of the filter;
- and
- the corrugated cross-section extends a substantial portion of the axial length of the filter.
