  • Suction module and hand-held power tool with a suction module
    Patent number: 8944182
    Abstract: A suction module which can be connected to a hand-held power tool, and a hand-held power tool including the suction module, is disclosed. The suction module includes a suction head which can receive a tool of the hand-held power tool that is rotatable around a tool axis and a fan with a fan wheel that is rotatable around a fan axis for suctioning air from the suction head. The suction head is connected to the fan by an intake channel, which in a first section runs along a longitudinal axis of the suction module and in a second section along a vertical axis of the suction module that is fixed transverse to the longitudinal axis. The fan axis runs parallel to a narrow axis, which is aligned transverse to the longitudinal axis and transverse to the vertical axis.
