Motorized portable blower apparatus

A portable hand-held blower comprising:

• a power source having an axis of rotation,
• a fan mounted on said power source to be driven thereby and located within a housing, said housing having an array of inlet apertures and a single main exit,
• a handle atop said housing and mounted substantially above the centre of gravity of said blower,
• said main exit having a generally S-shaped configuration to substantially align the path of air exiting said blower with said handle to prevent a torque being experienced by an operator holding said handle in use, and
• said fan being molded in a single piece from substantially rigid material;
• wherein said fan comprises:
• a generally flat disc each quadrant thereof having a plurality of generally radially extending blades which all extend on the same side of said disc,
• which all are rearwardly swept relative to the intended direction of rotation of the disc,
• which all extend to a predetermined height above a plane passing through said disc and substantially perpendicular to said axis of rotation,
• said blades being tilted transversely and in the direction of rotation of said fan either as a consequence of the manufacture of said blades, or as a consequence of the forces created by the operational rotational speed of said fan, and
• whereby each transversely tilted blade and its adjacent portion of said disc in front of each said blade forms an air scoop for said fan.
