1.3.2 Working
The air curtain blows a stream of either heated or unheated
air straight down, achieving the following:

ture differences (convection) is stopped.
•For heated air: the air entering across the floor due to
draught is heated.
•For unheated air: warm outside air is kept outside to sup-
port the air-conditioning in the room.
The air curtain is designed such that there is no need for air
filters.
