Patent attributes
An air-flow generating device, such as a blower, a vacuum, a mulcher, etc. The device may include a motor, a housing that supports the motor, and a passageway coupled to the housing and defining a passageway axis between a first opening and a second opening. The device may also include a fan assembly with a first axial fan and a second axial fan, and a transmission assembly coupling the first axial fan and the second axial fan to the motor. The transmission assembly may include a transmission shaft rotatable about a transmission axis substantially orthogonal to the passageway axis. An actuator may be operable to adjust the fan assembly about the transmission axis between a first condition, in which the first axial fan is positioned proximate the first opening, and a second condition, in which the second axial fan is positioned proximate the first opening.
