The core concept of all Vestergaard Toilet Service Units is to reduce operation time and to optimize aircraft lavatory main¬tenance. The basic feature of the unique vacuum evacuation system is to provide fast and clean emptying of the aircraft toilet system by means of a high velocity airflow. By effectively keeping the aircraft toilet and pipe systems clean, optimal preventive maintenance is ensured. The system effectively handles blockages from waste, including “irregularly” shaped items such as cans, diapers, soap bottles, etc.
