"In the event of a building catching fire, fresh air systems provide the necessary ""air flow power"". This way fire smoke can escape. Here, the coordinated interaction of fresh air and exhaust air solutions is crucial. Openings in the lower part of the building are equipped with fresh air drives, allowing fresh air to enter. It amplifies the thermal chimney effect, so that flue gases can escape through the vents at the top of the building. GEZE offers complete smoke and heat extraction solutions."
