The device has an air convection generator (9) with a blower unit (1, 3, 11) and an extraction unit (10, 12, 15, 16). The blower unit creates a barrier curtain by blowing out air, which separates a smoking area (8a) from a non-smoking area (8b). The extraction unit extracts the ambient air from the smoking area in the immediate vicinity of the blown out air and that the extent (6) of the barrier curtain only covers a fraction of the height of the smoking area. |
