Abstract
Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.
