Clean air runs parallel to the farm ceiling; it goes 360° uniformly in all directions, mixing itself with inside warm air, which is stratified on upper level. In this way you avoid direct cold air stream around animals saving energy consumption for heating, reducing humidity and rising dejections dryness. It is very important to underline that the uniformity of air flows do not depends on ceiling inclination.
