Abstract
Fabric drop-down diffusers are disclosed. An example drop-down diffuser includes an upper panel including an upper fabric sheet to be held in radial tension by an upper hoop. The upper panel defines a supply air inlet. The example drop-down diffuser further includes a lower panel to be underneath and spaced apart from the upper panel. The example drop-down diffuser also includes a circumferential fabric sheet to encircle the upper panel and the lower panel. The circumferential fabric sheet is to extend downward from the upper panel to the lower panel to define an air chamber bordered by the upper panel, the lower panel and the circumferential fabric sheet. The air chamber is connected in fluid communication with the supply air inlet.
