ABSTRACT:
A volute housing for a centrifugal fan, blower or the like includes a housing body defined by opposite spaced sidewalls with a generally circular fluid inlet opening in each sidewall and a volute peripheral wall disposed between the sidewalls and defining therewith a volute chamber. The sidewalls each have a first sidewall portion extending arcuately from a first zone of minimum radial dimension at a tongue of the volute chamber in the range of between 25 degrees to 320 degrees to a transition zone, and sidewall portions diverge progressively axially outwardly between the first zone and the transition zone to effect optimal fluid flow.
