ABSTRACT:
A blower is provided having a plurality of tubular nozzles removably attachable to the blower enabling an operator to easily vary the velocity and air discharge pattern. The blower forms part of an operator carried power tool having a drive motor spaced from the blower assembly by a tubular boom containing a drive shaft. The blower comprises a blower housing having an axial air inlet and an air outlet defined by a tubular section. An impeller is pivotally mounted within the blower housing and driven by the drive shaft. As the impeller is rotated, air is drawn through the air inlet and discharged through one of a plurality of tubular nozzles mounted on the blower housing tubular section. Tubular nozzles have varying geometries to conveniently vary the discharge air pattern.
