1. A fluid moving system comprising:
- a first fluid mover utilizing an impeller and having a fluid input and a fluid output in a generally side outlet;
the first fluid mover also having a second fluid outlet generally opposite the fluid input;
a second fluid mover utilizing an impeller and having an input generally axially coupled to the first fluid mover second fluid output, the second fluid mover also having a generally side fluid output; and
the first and second fluid movers also each having a flow gate coupled to the generally side output and each flow gate being operative to open, based, in part, on a fluid flow from an associated fluid mover.

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.
