A cooler-heater fan which differs from a conventional heater fan in that the air flow can be delivered in a slanted direction is described. The structure includes a heating apparatus, a fan motor and a fan blade assembly which are housed in a fan body, so that said fan body and the main body of the fan are separate structures. A tilt switch for safety shutdown is provided inside the main body. A spindle is provided in a tilted position protruding from the fan body. A spindle opening is provided in the main body to accommodate the spindle so that the latter can rotate therein. When the fan body is rotated to a slanted position to deliver the air flow, the main body stays upright, and the safety feature of the tilted switch is not affected. A hoop is also provided to secure the fan body. The hoop is made of a resilient metal wire and is used to secure the mounting of the fan body and allow a user to adjust the position of the fan body manually.
