Abstract

The invention relates to a fan (1), comprising: a central hub (2); a plurality of blades (3) connected to this hub (2) and extending at least more or less in radial direction, which blades (3) take a form such that when driven rotatably round the axis of the hub, an air displacement occurs; and drive means (4) for rotatably driving the blades (3) with the hub (2) round the axis of the hub. The invention provides a fan (1) of the stated type which has the feature that the end zones of the blades (3) are connected by a ring (6), which ring (6) is supported rotatably in an annular housing (7); the drive means (4) comprise a motor which is placed at a distance from the hub outside the air flow generated by the driven blades; the axial dimension of the ring and that of the annular housing is a maximum of 0.2 x the diameter; and the annular housing is supported by supporting means, for instance a foot (8, 9) for placing on a surface.
