Abstract

The invention concerns an air blower including a centrifugal fan which is driven by an electric motor. The blower has a two-part blower housing comprising an upper housing which encloses the motor beneath the motor cap and a lower housing. The centrifugal fan is disposed in the chamber between the upper and lower housing. The plenum around the fan leads to an outlet from the blower. An intake shield extends across and blocks undesired entrance of objects into the inlet opening in the bottom of the lower housing. The blower may be seated on a lid across an opening in it. An adapter in the lid receives the intake shield and has its own air inlet to the blower. The orientation of the blower with respect to the lid is rotatable. Cooperating flanges on the blower and the adapter hold the blower to the lid at two rotative locations and a button latch arrangement latches the blower at each of the two arrangements. Between the two latched orientations, the blower may be lifted free of the lid.
