A tiltable fan assembly adapted to exhaust air at a variety of angular orientations. In a preferred embodiment, the tiltable fan assembly includes a generally flat base member adapted to rest on a table top or similar surface. The base member is shaped to include a pair of horizontally-extending, cylindrically-shaped sleeves. The fan assembly also includes a pair of mounting posts, each mounting post being angularly adjustably mounted about its longitudinal axis within its respective sleeves and being appropriately sized to extend out through both ends of its respective sleeve. A rotary switch is angularly adjustably mounted on the outer end of one of the mounting posts, and a cap is fixedly mounted on the outer end of the other of the mounting posts. A pair of gaskets are fitted onto the inner ends of the mounting posts. The fan assembly further includes a fan unit and a neck assembly, the neck assembly being used to couple the fan unit to the angularly adjustable mounting posts. The neck assembly preferably includes a pair of neck elements, the first neck element being integrally formed with the fan unit and having a semi-cylindrical bottom portion. The second neck element is semi-cylindrical in shape and fits together with the bottom portion of the first neck element over the inner ends of the pair of mounting posts. The pair of gaskets on the mounting posts serve to mechanically couple the mounting posts to the neck elements.
