Abstract
A dust removal system handheld power tool includes a fan () to generate an air flow (), a suction nozzle () to capture dust-laden air from a tool (), and a collecting container () to collect the dust. The collecting container () has a suction opening () connected to the suction nozzle () as well as an exhaust opening () connected to the fan (). A filter () serves to separate dust into the collecting container () and is arranged so as to cover the exhaust opening (). The filter () has several consecutive fins () arranged one beside the other in a direction (y) that is perpendicular to the direction (z) of the air flow (). The fins () are slanted with respect to each other. The slant () of the fins () reduces the adhesion of the dust to the fins ().
