The MWI has been engineered and designed to bring fresh air into the house without exposing the animals to cold air drafts. This is made possible with the MWI’s geometrical shape, that properly channels the incoming fresh air along the ceiling, to mix before it reaches the animals.The MWI is ideally designed for installations in the house walls. Highly flexible and versatile application, the inlet can be tailored to the building of any size with two available width dimensions and 2 available heights.
