An extractor fan head, especially for incorporation into roofs, has a hollow top-part, located at a free distance from the base-part, for obtaining an air-current that passes through it at right angles to the longitudinal axis of the head. Air-conditioning partitions between the top and base parts are distributed around the circumference. The partitions are formed as air-rise ducts, open to the base-part and ending in the hollow space of the top-part connected with the distant section by way of at least one perforation, offset against the cross-section of the aperture of the air-rise ducts and located at the bottom of the top-part.
