Patent number: 9597624Abstract: In a preferred embodiment, an angle grinder has a housing containing its electromotive drive, the housing having a free end from which an electric power cable extends, the free end having air intake openings via which cooling air is drawn into the housing. A filter assembly has a body and a filter medium supported by the body, the body being detachably attachable to the free end of the housing via, in some embodiments, latching projections. The body and the filter medium together form a projection-free outer face of the angle grinder when the filter assembly is attached to the free end of the housing. Air drawn into the air intake openings enters the filter assembly by way of the projection-free outer face and passes through the filter medium prior to being drawn into the air intake openings. The filter assembly may include a slotted opening through which the power cable extends.Type: GrantFiled: May 13, 2015Date of Patent: March 21, 2017Assignee: Metabowerke GmbHInventor: Matthias Hiller
