ABSTRACT:
A fan assembly has a main body support and a mounting member which are inclined at a predetermined angle thus permitting the fan assembly to be mounted either adjacent to the upper edge of a wall or in a corner of a ceiling. A rotating grill disperses a current of air over a relatively wide area. The main body support has a groove which accommodates a mating engageable member of the mounting member thus permitting the fan assembly to be securely mounted to a wall or a ceiling.
