ABSTRACT:
An overhead suspended fan has a canopy with a top seal on a support shaft and a bottom seal which is mounted on a rim of a cup-shaped member supported above the motor housing bearing and which has an annular portion engaging the inside of the bottom portion of the canopy and an open shoulder upon which the bottom end of the canopy rests; an inner lip on the annular portion of the bottom seal defines a groove interlocking with the rim of the annular member. An outward and downward flaring skirt on the second seal forms a narrow restricted clearance with a frustoconical portion of the motor housing; a second cup-shaped member mounted on the top portion of the housing has a rim extending upward within a depending annulus of the second seal to prevent water flow to the housing bearing.
