Abstract: A sound attenuating enclosure with sound absorbing panels. The panels are positioned in an array of four side panels and a top panel. The array of panels is covered with vinyl material forming seams between adjoining panels and flaps for securing the panels together to form the enclosure. Each of the panels is provided with a pouch having a resealable opening for containing a flat sound reflecting element. One predetermined side panel is provided with apertures for allowing supply lines to pass through the enclosure.

Abstract: A wire raceway member, for containing the wires which extend between a fan motor and its separate control module, is formed of a lower U-shaped portion and an upper expandable portion. An opening in the expandable portion is normally smaller than the diameter of the wires to be contained but, when temporarily expanded, the width is wider than the diameter of the wires so as to enable the insertion of the wires into the slot. The ends of the raceway have integrally formed members that are attachable to the motor and to the orifice ring, respectively, without fasteners. A radially extending portion of the grille cover is aligned with the top slot of the raceway member so as to thereby act as a cover to prevent the inflow of moisture into the raceway member.
