Abstract
A lightweight air blower attachment for a portable power unit such as a hand held internal combustion engine. The blower attachment includes a generally tubular shaped housing adapted for close coupling of the blower to the power unit. The housing provides a shroud and a support for an axial flow impeller having a shaft which extends through a mounting boss on the housing and includes a drive tang adapted to be drivably connected to a power takeoff shaft. The blower includes an elongated nozzle having a handle portion and being rotatably mounted on the housing to provide for changing the direction of the exit air flow without rotating the entire power unit and blower attachment. The nozzle is provided with a conical portion which converges to a throat and transitions to a somewhat flat circular sector shaped air exit portion providing for an air flow pattern particularly adapted for sweeping and dusting operations.
