Abstract
A centrifugal air blower unit includes a casing comprising two separable sections which enclose a centrifugal impeller. The impeller has a hub including a threaded bore for attaching the impeller to the distal end of a drive shaft extending from a support of a portable power unit. The casing is adapted to mount on a support housing for the drive shaft. The hub of the impeller includes a portion extending in a direction opposite to the threaded portion and through an opening in the bottom wall of the casing whereby the impeller may be threaded onto and off of the drive shaft for connecting and disconnecting the blower unit to the bearing housing without disassembly of the casing. The casing includes a mounting pad formed integral with one of the casing parts and supported by a plurality of spaced apart radially projecting webs forming an air inlet opening and also forming combination inlet guide vanes and a trash guard for the impeller.
