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.
