Abstract
A port is employed for a fan chamber which defines a volume formed by at least one generally continuous vertical wall connecting a horizontal base wall with an opposing horizontal exit wall. Within the volume is a fan rotatable in a plane generally parallel to a plane of at least one of the horizontal walls. The port is formed of an inner side located between a center of the exit wall and an outer edge of said the wall, an outer side located between the inner side and the outer edge of the exit wall, and two opposing secant sides connecting respective ends of the outer side to the inner side. A shape of the inner side forms a straight line or a convex line with respect to the center of the exit wall.
