  • Patent number: 11105341
    Abstract: An air moving device according to the present disclosure can include a housing and an installation hub. The housing can be connected to the installation hub via one or more adjustable supports. An impeller can be installed at least partially in the housing and configured to direct air out of the housing. In some embodiments, the adjustable supports can be adjusted to move the housing with respect to the installation hub. For example, the adjustable supports can be configured to modify the tilt of the housing and/or the overall distance between the housing and the installation hub. The installation hub can be installed on a ceiling, wall, or other mounting surface. Adjustment of the adjustable supports can permit vertical alignment of the air moving device housing, even when the installation hub is mounted to a slanted or sloped (e.g., non-horizontal) ceiling or wall.
