Patent attributes
A tapered flexible conduit and a ventilation system incorporating the same. The conduit is arranged to extend between a register and a fan assembly, such as in a whole house fan (WHF) system. The conduit includes a flexible inner liner surrounded by a flexible outer liner. The flexible inner liner has a length of helically formed wire coupled to a flexible membrane. The flexible outer liner includes an insulative layer to provide acoustic baffling for an airflow established by the fan assembly passing through the conduit. The tapered conduit has a frusto-conical shape along an overall length of the conduit to sealingly engage differently sized inlet and exhaust ports of the register and the fan assembly, respectively. The collapsible nature of the respective inner and outer liners reduces bulk during shipment and accommodates a variety of different configurations during installation.
