ABSTRACT:
A portable air blower includes a flexibly resilient housing, a motor mounted within the housing, and a blower wheel fixed to a motor shaft. The motor is bolted at one end to a motor mounting bracket which, in turn, is attached to the housing by a plurality of first shock mounts. Each such first shock mount includes a bolt for connecting the motor mounting bracket with the housing, and a resilient elastomeric grommet interposed between the bolt and the bracket. A self-clinching nut fixes the bolt to the housing. The motor shaft rotates through a self-aligning bearing held by a pyramid-like support bracket which is attached to the housing by a plurality of second shock mounts. The second shock mounts are identical to the first shock mounts, and include a resilient elastomeric grommet interposed between the support bracket and the bolt.
