The exhaust air is blown out with a very long and narrow throw pattern so that the exhaust air will not get mixed with fresh air. This will not cause moisture or odour problems if the nozzle opening protrudes from the wall surface and the exhaust velocity is sufficient. This, of course, requires that the exhaust is not directed into shafts or closed inner yards. Waste air exhaust through a wall always requires permission from the building authorities.
