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 have an elongate planar portion supported by rods extending outwardly on either side of the planar portions to support the blades in the slots. The blades are removable without disassembling the entire diffuser. Each bridge has an arcuate cover that reduces air drag and each bridge also has a low profile to further reduce air drag and thus reduce noise produced by the diffuser.
