<p>A ventilation device has a body (1) with a through opening and a flat rear contact surface. The ventilation device further has a fan (14), which is ar- ranged in the body and adapted to be mounted indoors on a mounting sur¬ face of a wall or a ceiling in such a manner that the contact surface of the body (1) is in close contact with the mounting surface and the opening in the body is positioned right in front of a ventilation duct which opens into the mounting surface. The fan (14) is coaxially arranged in a ring (8), which is pivotally connected to the frame (1) and pivotable about a pivot axis (9), which extends parallel to the contact surface of the body (1), between a position of use, in which the ring (8) is located right in front of the opening in the body (1 ) and its centre axis extends substantially perpendicularly to the contact surface, and a service position, in which the ring (8) is pivoted away from the opening.</p> |
