Assignee:

Air System Components L.P. - Dayton OH

International Classification:

F24F 700

US Classification:

454303

Abstract:

A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades include an elongate planar portion supported by rods extending outwardly on either side of the planar portions to support the blades in the slots. At a lower end of each planar portion opposite the rods is a foot that extends perpendicularly outward therefrom. Each side rail includes an inwardly projecting flange that is sized and positioned to slidably receive the foot of an associated blade such that the blade may be manually moved both within the slot and along the flange to properly position the blade during the installation or subsequent modification. The blades are easily and rapidly removed without requiring full disassembly of the diffuser or removal of the diffuser from its installed location.

Abstract:

A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades include an elongate planar portion supported by slot following pegs extending outwardly on either side of the planar portions to support the blades in the slots. The bridges include a spring mechanism to provide bias to the blades to prevent wedging and rattling. The bridges also include a top arcuate cover that reduces air drag and noise.
