A bellows assembly is provided in which a retainer member is formed as an aluminum extrusion with two uniformly spaced recesses formed therein. A bellows is provided with two uniformly spaced attachment members which coact with the spaced recesses to provide a uniforma bellows profile for its entire length. Accordion pleat members are provided to attach the ends of the bellows to the ends of the retainer member.

Snap-secured bladder for air-distribution terminal

A bellows assembly is secured to a retainer by extrusions having a mushroom or arrow shaped cross section. Air flowing through the terminal impinges upon an impervious film covering the central portion of the device and is diverted into two flow paths. Initially the flow paths extend between the film and the cutoff plates which coact to form a tight shut off. Downstream of the cutoff plates, the flow paths are between a porous foam covering the bellows and foam surrounding the cutoff plates to provide a sound reducing effect. If necessary or desirable, the back of the retainer may be covered with foam or other suitable sound insulating material.
