Abstract
Abstract Ventilating apparatus for a building includes a flexible duct with perforate side walls which is supported by a wire stringer which extends interiorly and longitudinally of the duct. One end of the stringer is connected to a fan housing located in the rigid duct at the inlet of the flexible duct, and the remote end of the stringer extends through an opening in the flexible duct adjacent the end of the duct for connection to the building frame. The stringer and the flexible tube are conveniently supported at intervals by hangers which have hooks respectively connected with the building and with the stringer. The rigid portion of the ventilation duct has an end extending through an opening in a building wall to provide an exterior air inlet port. The rigid duct also includes opposed side air entry ports for recirculating inside air and a damper assembly for selectively closing outside air flow or admitting outside air for mixture with inside air.
