Abstract

A blower has a blower tube and a fan unit that conveys an air flow through the blower tube. The fan unit has a fan having a fan axis. The fan conveys the air flow in the direction of the fan axis. The air flow exits the blower tube in an outflow direction at a tube aperture. The handle has on its lower side a grasping point, which in the operating position of the blower, lies on a vertical axis through the blower's center of gravity. The tube aperture has a center axis that is oriented in the outflow direction. So that the forces received by the user at the handle during operation can be made smaller, it is provided for the spacing from the center axis of the tube aperture to the grasping point to be smaller than the spacing from the fan axis to the grasping point.
