Abstract
A fluid moving system is disclosed wherein a plurality of stacked blowers may provide for the redundant supply of cooling fluid such as air. This system may be advantageously utilized to cool electronic equipment or other uses. One or more of the blowers may utilize an impellor design that allows for the axial flow of fluid through the blower in addition to a transverse fluid outlet. In addition, the blowers may incorporate a flow gate operative to reduce back flow should a particular blower have a reduced fluid flow.
