Abstract of WO 2009100821  (A1)

The invention relates to a battery-operated hand-held power tool (2), especially an angle grinder, comprising a housing base (4) accommodating the electromotive drive components and air inlet openings (10) supplying the electromotive drive components with a cooling air flow. In order to protect the electromotive components from dirt, the hand-held power tool is designed in such a manner that a filter element (20) is provided in the area of the air inlet openings (10) and keeps dust, especially magnetizable dust, away from the electromotive drive components. The filter element (20) is retained by a filter retaining part (12, 30) which can be attached to the exterior of the housing base (4). The filter retaining part (14, 30) can be elastically deformed to such an extent that it is slightly deformed, especially expanded, when attached to the housing base, and engages behind or snaps into an element on the housing base.
