Abstract: A material collection device for a hand-held power tool includes a material collection container for collecting material removed during operation of the hand-held power tool. At least one opening of the material collection container is for feeding the material into the material collection container and is arranged in an opening plane. At least one mounting unit is for mounting the material collection container on the hand-held power tool. The at least one mounting unit includes a channel element for connection to an ejection port of the hand-held power tool. A channel longitudinal axis of the channel element is arranged transversely to the opening plane of the material collection container in at least one section plane running perpendicularly to the opening plane.

Abstract: A hand-held sanding machine includes at least one sanding device for receiving or configuring a sanding apparatus. The sanding device includes at least one fan for conveying away material subtracted in a sanding procedure, at least one drive device for driving the sanding device, and at least one connecting housing unit which at least partially receives the sanding device. An internal wall of the connecting housing unit that delimits a fan receptacle region is configured for guiding an air flow generated by the fan. The internal wall is funnel-shaped about a rotation axis of a driveshaft of the drive device.

Abstract: The invention relates to a fan, particularly a radial fan, having a fan hub with a rotational axis. A plurality of fan blades is disposed about the rotational axis for deflecting an air flow. The invention provides that an adjustment device is provided at the fan blades for the rotational speed-dependant adjustment of an air flow.
