Abstract
A centrifugal blower assembly comprises a scroll wall and a pair of opposing sidewalls. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. The blower outlet defines a blower outlet area. An adjustable outlet plate is pivotably coupled to the pair of opposing sidewalls such that the adjustable outlet plate is moveable between a first position to define a first blower outlet area and a second position to define a second blower outlet area.
