Mechanical systems generally utilise a smoke shaft and are often more efficient, sometimes requiring a very small smoke shaft.Ī mechanical system is useful where space is at a premium and/or natural airflow is insufficient to achieve the required performance. Mechanical smoke ventilation systems use powered elements such as fans to force the movement of smoke to allow it to escape through dampers, grills and vents.
