Abstract: An evacuation device (1) for transporting gas and/or particles out of a room includes mounting elements (7, 9) for installation in a wall (3) of the room such that an inflow end (6) is located on the face of the wall (3) that faces the inside of the room and an outflow end (8) is located outside the room. The evacuation device includes a duct (2) extending between the inflow end and the outflow end, and a barrier (12) is releasably attached in the duct to seal it when the evacuation device is in a standby state. Driving elements (21) are arranged to guide at least one flow of fluid through the duct when the evacuation device is in an activated state. Preferably, the duct includes a venturi nozzle, and the driving elements include a number of water nozzles located upstream of the inflow end of the venturi nozzle.
