Abstract (en)
[origin: EP2465647A2] The tool (100) has a housing wall (110), and a fan device having air suction unit (114) and air outlet (116). The fan device has an air guide element (130) and discharge chambers (142,143). The surface contours (161,162) of housing wall are extended to downstream side (124) of the air suction unit. An air guide element (131) is shaped such that the cross-sectional area (Q) of discharge chamber set transverse to the downstream direction (127) of air suction unit, increases with the increasing distance from the downstream side in downstream direction.
