The hand-held
air blower has a hollow, substantially cylindrical housing with an open front end, a plurality of air intake openings, an
impeller situated within the housing
proximate the intake openings, a motor for driving the
impeller, and battery means for powering the motor. A
concentrator attachment is designed for use with the blower. The
concentrator has means for removably attaching the
concentrator to the open front end of the blower housing and a hollow shell. The shell includes an intake section with a
diameter substantially equal to the
diameter of the front end of the housing and an outlet section with an outlet opening substantially smaller than the
diameter of the front end of the housing. A truncated football-like shaped balancing member is provided. The balancing member has a central air flow channel. Radially directed elements
mount the balancing member within the intake shell section with the balancing member spaced from the interior surface of the intake shell section so as to permit air flow therebetween.
