Ventilation determines how much fresh air the animals get and how quickly moisture, heat and gases leave the building.
We calculate the air exchange for the specific building and stock and design a system that works in every seasonal mode.
In pig buildings air must be renewed without draughts at animal level. We choose the inlet and exhaust layout for the type of room and the building structure.
Schematic, not to scale.
Three typical systems from the Exafan catalogues for different types of rooms. Switch between Winter and Summer to see how the air path changes. For a given section we choose the scheme for the type of room and the building structure.
Negative pressure in winter, positive pressure with cooling in summer. Gestation and insemination.

Air exchange changes with the weather and the age of the animals.
In winter it is kept to a minimum so the building does not chill, in summer it is at its maximum. Between these modes the controller brings in further ventilation stages step by step.
Where the air goes matters as much as how much of it there is: incoming air should mix with the room air rather than fall on the animals as a cold stream.
