The invention relates to a multicartridge diesel soot particulate filter (100) comprising a casing delimiting the outer boundary of a filter volume. The filter has a central filter axis (170). The casing has an inflow side and an outflow side defining an average flow direction being substantially parallel to the central axis. The filter volume is filled with at least two filter cartridges, each of these filter cartridges having a central filter cartridge axis (170). The central filter cartridge axis (170) of the filter cartridges is substantially parallel to the average flow direction of the filter. The filter cartridges comprise a porous structure (101) comprising metal fibers. The filter cartridges provide a radial flow direction through said porous structure (101). The flow through the multicartridge diesel soot particulate filter is axial while the flow through the filter cartridges is radial. The invention further relates to a method of manufacturing a multicartridge diesel soot particulate filter.
A multicartridge diesel soot particulate filter comprising a casing delimiting the outer boundary of a filter volume, said filter having a central filter axis, said casing having an inflow side and an outflow side defining an average flow direction, said average flow direction being substantially parallel to said central filter axis, said casing being gas impermeable in a radial direction, said filter volume being filled with at least two filter cartridges, each of said filter cartridges having a central filter cartridge axis, said central filter cartridge axis being substantially parallel to the average flow direction of said filter, said filter cartridges comprising a porous structure comprising metal fibers, whereby said filter cartridges provide a radial flow direction through said porous structure.
