The present disclosure is directed to a filtering assembly and a method of manufacturing a filtering assembly. The filtering assembly may increases an effective screening area. Specifically, embodiments disclosed herein include a screen housing having two sidewalls and two end walls, defining a perimeter with a length and a width. The screen housing also includes a top face and a bottom face. A plurality of screen segments may be positioned on the top face of the screen housing, such that the plurality of screen segments on the top face provide a screening surface area less than a total surface area of the top face.

A coupling filter for a fluid system comprising a molded hollow tubular body having a wall defining a flow passage, a porous filter element of generally parabolic cross-sectional shape with a base portion extending across the entire flow passage and a pair of wing portions extending longitudinally of the flow passage and converging toward the base portion. In one form the base portion is cylindrical and in another form it is W shaped with a series of flat mesh panels presented to the flow path.

A disclosed screening apparatus includes a subgrid, and a screen element attached to the subgrid via laser welding at a plurality of attachment positions such that, under vibrational excitation, the screen element has a pre-determined profile of vibrational motion relative to the subgrid. The screen element may be attached at a maximal number of attachment locations to the subgrid to minimize relative motion of the screen element and the subgrid under vibrational excitation, or the screen element may be attached a sub-set of the maximal number of attachment locations to allow vibrational motion of the screen element relative to the subgrid. A disclosed method may include attaching a plurality of screen elements to a respective plurality of subgrids, attaching the plurality of subgrids to one another to form a screening pre-assembly, and cutting edges of the screening pre-assembly to form the screen assembly having a perimeter with a pre-determined shape.

A filter device is configured to filter a liquid. The filter device includes a drum sized to receive the liquid and a plurality of filter panels coupled to the drum to define a plurality of discs. The liquid passes through at least a portion of one of the discs. Each filter panel includes a perimeter frame that defines a panel normal flow area and a filter media coupled to the perimeter frame. The filter media may be adapted to include a plurality of pleats.

Provided are filter elements or cells and filtration assemblies or capsules for purifying and/or clarifying fluids used during various biopharmaceutical applications, for example, chromatography or depth filtration, and processes for making and using the same. A filter element comprises a media pack comprising two sides and a separator element located between the two sides, at least one side comprising a filtration media, wherein an inner edge periphery and/or an outer edge periphery of the filtration media comprise a bond directly to a portion of the separator element.

A fluid filter apparatus comprising an upper housing shell; a lower housing shell; a pleat pack element comprising a peripheral frame and a folded pleated media. The frame is at least partially molded over the media to secure the media in the frame, and the media comprises two or more types of media of different densities from each other. A flow control element is disposed for changing the proportion of flow between the first media and the second media responsive to changes in at least one of temperature, pressure, flow rate and/or viscosity of the fluid.

A fluid filter element comprising: an embossed flat filter material which is folded so as to define a plurality of substantially adjacent walls, each wall defining a planar surface between two adjacent fold lines, said wall having an embossing comprising: a first embossing row having a centrally located elongated positive embossment and a distal embossment at each end of the positive elongated embossment, wherein at least one distal embossment is negative; and, a second embossing row spaced from and parallel to the first embossing row, the second embossing row having two elongated embossments, wherein one elongated embossment is negative and one is positive. A method regarding the making of the same.
