Abstract: Air flow in a hollow wall, ceiling, or floor is created by forcing air into or drawing air out of the wall, ceiling, or floor through a hole around a pipe through which the pipe extends from the wall, ceiling, or floor. The apparatus of the invention includes a body that fits around the pipe to position an end against the wall, ceiling, or floor surrounding the pipe and hole and provides for the connection of an air flow hose thereto. The air flow hose provides a source of pressurized air or a source of vacuum to force air into the wall, ceiling, or floor or draw air therefrom.

Abstract: Apparatus for creating a flow of air in a hollow wall or ceiling to aid in drying a wall or ceiling which has become wet generally through a disaster such as broken pipes, flooding, leaking roof, includes a conduit having a first end sized and configured to fit and be secured over and around an opening in a wall or ceiling which has an electrical box mounted therein. The conduit will generally be provided with holes positioned to be aligned with the usual cover plate mounting holes in a wall switch or outlet, or fixture mounting holes in the box itself, through which screws can be positioned to effect securement of the conduit. A second end of the conduit is configured to accept the end of an air supply hose or a vacuum supply hose, such as extending from the outlet or the inlet, respectively, of a usual air blower, and an air flow passage extends from the second end to the first end to direct air into or draw air from the wall or ceiling through and around the electrical box.

Abstract: Apparatus for directing pressurized drying air into a hollow wall or ceiling to aid in drying a wall or ceiling which has become wet generally through a disaster such as broken pipes, flooding, leaking roof, etc., without removing a portion of the structure, but by merely removing a standard wall switch or outlet cover plate, includes a conduit having a first end sized and configured to fit over and around an electrical box as installed in a wall or ceiling and to be secured thereover. The conduit will generally be provided with holes positioned to be aligned with the usual cover plate mounting holes in a wall switch or outlet, or fixture mounting holes in the box itself, through which screws can be positioned to effect securement of the conduit.
