Abrégé

There is provided an active airflow inhibiting apparatus (10) for an entranceway (4, 6) comprising: a structure (12) configured to be positioned adjacent an entranceway of a building (2) and defining a passage therethrough for accessing the entranceway; wherein the structure defines at least one plenum chamber (18) and first and second outlet slots (24a, 24b) fluidically coupled to the plenum chamber; a fan (20a, 20b) fluidically connected to the plenum chamber for supplying an airflow to the plenum chamber in order to selectively form a jet of air from the first outlet slot in a first mode of operation and from the second outlet slot in a second mode of operation; wherein the first and second outlet slots are configured so that the respective jets of air are each directed towards a centre of the structure, with the jet of air from the first outlet slot being directed away from the entranceway and the jet of air from the second outlet slot being directed towards the entranceway.
