Abstract (en)

[origin: WO2021094281A1] Disclosed is an axial extension part which enables the use a filter cartridge (25) of larger axial dimensions than a standard filter cartridge for which the axial depth of a recess (11) of a housing (10) of a selective catalytic reduction device (SCR) has been provided. This makes it possible to have different filtration properties, without the need to modify the casing. The filter cartridge (25) of larger dimensions can be inserted in the extension part when this part is mounted in the recess (11) of the housing (10). The cartridge is enclosed there, in a sealed manner, when the closure plug (21) is put in place in order to close the opening at the rear end of the part.
