An Axial Fan

摘要

An axial fan has a motor and an impeller housed within an outer casing, the fan further comprising a mounting assembly for mounting said motor within said casing. At least one elongate vane extends between the inner wall of the casing and the motor and is connected to the motor by means of a connector assembly comprising means for connecting said vane to said motor at a selected one of a plurality of distances from said impeller. In one embodiment, this can be achieved by means of a plurality of discrete mounting holes defining the respective distances.
