Abstract
An apparatus for supplying air to a compartment. The apparatus has at least one air-inlet opening which is closable by a flap mounted to swing freely. At least one blower is provided. In order to avoid creating drafts, an electromagnet is mounted on the frame which surrounds the air-inlet opening, and the flap has an armature or member which cooperates with the electromagnet in the closed position of the flap.
