Abstract

The invention relates to a fan system (1) comprising a frame (2) for mounting of the fan system, for instance on a ceiling of a building. A motor (3) is arranged in the frame. The motor drives a rotatable shaft (4). A number of fan blades (5) are attached at an angle of tilt to the rotatable shaft (4). The angle of tilt lies substantially between 15 and 25 degrees, and is preferably substantially 20 degrees.
