摘要

The tank (1) has a filler neck (2) for filling reducing agent in the tank, and a filtering apparatus (4) i.e. cascade filter, detachably arranged in the filler neck for preventing dirt particles from entering into the interior of the tank. A pumping module (3) injects reducing agent proportions supplied by a dosing module into an exhaust line of a combustion engine.
