System and method for shaping a duct section

A system for shaping a semi-rigid duct section prior to installation of the semi-rigid duct section at an installation site, the semi-rigid duct section being configured to be manually shapeable, the semi-rigid duct section being configured to expand from a flattened configuration to an expanded configuration, the system comprising:

• an inflatable enclosure insertable within the semi-rigid duct section while being in the flattened configuration, prior to the installation of the semi-rigid duct section at the installation site, the inflatable enclosure defining an opening for inflating the inflatable enclosure;
• and
• a blower for inflating the inflatable enclosure through the opening from a deflated configuration to an inflated configuration, prior to the installation of the semi-rigid duct section at the installation site;
• wherein when the inflatable enclosure is inserted within the semi-rigid duct section, the blower inflates the inflatable enclosure through the opening from the deflated configuration to the inflated configuration, prior to the installation of the semi-rigid duct section at the installation site, whereby the semi-rigid duct section expands from the flattened configuration to the expanded configuration as the inflatable enclosure pushes against the semi-rigid duct section from within, and wherein when the inflatable enclosure is deflated via the opening then the inflatable enclosure is removed from within the semi-rigid duct section, prior to the installation of the semi-rigid duct section at the installation site;
• wherein the inflatable enclosure includes a handle for removing the inflatable enclosure from within the semi-rigid duct section.
