More Information
Summary:The disclosure relates to an electric blower apparatus having a blower spiral which has a first axial end wall, a second axial end wall and a blower air outlet. An electric motor which drives a fan wheel rotating in the blower spiral is held on the first axial end wall, the fan wheel inducting ambient air by way of an intake opening in the second axial end wall. A cover element, the cover surface thereof being configured so as to be larger than the air inlet surface of the intake opening, is disposed in front of the intake opening. To induct a large quantity of ambient air with little noise, it is provided that the cover element is configured as a cover plate, wherein an annular gap which forms the intake channel for the direct access of ambient air is configured between the plate edge and the blower spiral.
