Abstract

Air curtain with an auxiliary stream, which is used to protect rooms against the impact of external factors (weather conditions, volatile substances, particulate solids, insects etc.), as well as to protect rooms against the outflow of internal air outside, characterised in that the air exhausts (6, 7) form at least two separate air streams, the main stream (A) is directed towards the construction hole at the limit of the room, while the auxiliary stream (C) - into the room at an acute angle in relation to the plane of the construction hole, and the main stream (A) and the auxiliary stream (C) do not cross each other.
