providing a housing and a blower wheel, the blower wheel comprising backward-curved blades configured to rotate in a rotational plane; and
positioning the blower wheel in the housing such that the housing forms a hexagonal cross-section around at least a portion of the rotational plane and such that there exists:
a first distance measured radially outward from a center of the blower wheel to a first side of the hexagonal cross-section; and
a second distance measured radially outward from the center of the blower wheel to a second side of the hexagonal cross-section, wherein the second distance forms a first angle with the first distance, the first angle being an acute angle, and wherein the first distance and the second distance are unequal and less than a diameter of the blower wheel.
