A nozzle for an exhaust fan that has a primary, central aperture for exhaust. Arranged around the periphery of the central aperture is a plurality of side apertures. The nozzle fits over the fan outlet. A stack may extend upwardly from the central aperture. Exhaust exiting the side apertures induces a flow of ambient air, especially when a windband encircles the nozzle. The ambient air increases the volume of exhaust exiting the windband.
