An electrically regeneratable filter element comprises at least two flanks, each of these flanks comprising a stiff material layer. Each of these flanks has at least one thermally and electrically insulated side. The filter element comprises further a metal fiber fleece being pleated according to pleating lines providing an edge with pleat openings. The metal fiber fleece is mounted between the flanks, in such a way that the thermally and electrically insulated sides make contact with the edge, meanwhile these sides closing the pleat openings.

Electrically regeneratable filter element

A filter element comprises a pleated metal fiber fleece which is pleated according to pleating lines, providing an edge with pleat openings to be closed to make gas flowing through the metal fiber fleece. The filter element comprises at least two flanks, each of these flanks comprises a ceramic plate. The metal fiber fleece is mounted between the ceramic plates of both flanks, while flanks exercising a clamping force on the edges of the metal fiber fleece in a direction essentially parallel to the pleating lines, meanwhile closing the pleat openings.

Diesel exhaust filter system with electrical regeneration

A filter element comprises a pleated metal fiber fleece being pleated according to pleating lines providing an edge with pleat openings to be closed in order to make gas flowing through the metal fiber fleece. The filter element further comprises at least two flanks, each of these flanks comprising a stiff material layer. The stiff material layer and the metal fiber fleece are connected using a layer of ceramic adhesive, which prevents direct contact of the metal fiber fleece over the length of the edge of the metal fiber fleece with the flank. Meanwhile the flanks, being essentially perpendicular to the pleating lines, closing the pleat openings in order to prevent bypasses.

Filter element

A filter element comprising a pleated metal fiber fleece is pleated according to pleating lines, providing an edge with pleat openings to be closed to make gas flowing through the metal fiber fleece. The filter element comprising at least two flanks, each of these flanks comprises a thermally and electrically insulating fabric and a stiff material layer. The thermally and electrically insulating fabric is present at one side of the stiff material layer, providing a thermally and electrically insulated side to the flank. The metal fiber fleece is mounted between the thermally and electrically insulated sides of both flanks, which exercise a clamping force on the edges of the metal fiber fleece in a direction essentially parallel to the pleating lines, while the flanks closing said pleat openings.

Filter element comprising pleated metal fiber fleece

An electrical contact system is provided which comprises an electrically conductive porous fleece and one or more contact bodies. The electrically conductive porous fleece and the contact bodies are sintered to each other, so avoiding hot spots during the use of the element.
