A fan (10) is disclosed having a base (11) and a protective housing (12) encasing an electric motor (13) and a blade assembly (14). The base has two pivot mounts (21) to which a front support leg (22) and a rear support leg (23) are mounted. Each leg includes a mounting flange (24). The pivot mounts allow the pivotal movement of the protective housing relative to the pivot mounts and about horizontal axis AA. The base also includes a ceiling mount portion (28) which is mounted to the ceiling C. The ceiling mount portion includes a mounting plate (32), a rod (33), and a cup-shaped coupler (34). The coupler has an annular groove (35) therein adapted to receive the mounting flanges. The coupler is configured to allow the flanges to be rotated while nested within the groove, thereby allowingpivotal movement of the fan about the rod and about vertical axis AB.
