Abstract

The present invention relates to a reducing agent filter device (23) comprising an inner filter unit comprising a first filter element (26) and a second filter element (28) which extend in an axial direction (X) and a direction perpendicular to the axial direction (D) of the filter device. The second filter element (28) is arranged coaxially with the first filter element (26) and the first filter element (26) surrounds the second filter element (28). The second filter element (26) constitutes a hollow central tube (25) of the reducing agent filter device. The filter device further comprises an outer filter unit (29) comprising a third filter element (30), which at least partially surrounds the inner filter unit (27). The present invention also relates to a reducing agent dosing unit comprising a pump device and the filter device, a reducing agent dosing system comprising a tank for the reducing agent (20), the reducing agent dosing unit and an injection device (60) arranged to inject the reducing agent into the exhaust gas system, and a vehicle (1) comprising the filter device and/or the reducing agent dosing system.
