Abstract
Fabric drop-down diffusers are disclosed. An example drop-down diffuser includes a first fabric sheet. The first fabric sheet is to extend away from a ceiling at a location adjacent a supply inlet. The supply inlet is to provide a flow of air toward the first fabric sheet. The example drop-down diffuser also includes a blanking sheet to restrict air flow through the first fabric sheet. The blanking sheet is to be disposed on an interior surface of the first fabric sheet. The blanking sheet has a lower permeability than the first fabric sheet.
