They allow either a simple manual airflow adjustment, or the airflow is automatically controlled, depending on the humidity of the room. Slot ventilation, which works with respect to room humidity, does not require power supply, works on the principle of a polyamide tape. Slot ventilation in the form of air grilles may also have an acoustic fitting that prevents extreme sound from entering the room. When cold weather is too cold, the slots can be closed manually.
