The key to peace and well-being, energy efficiency and building protection lies in our air. Especially in the manner in which it enters the room. Thanks to modern AERO window ventilators, this happens with the windows closed – as quiet as a whisper, needs-based and independent of user. Maximum heat recovery, pollen or fine dust filters and clever comfort functions ranging to automatic humidity control are naturally possible. Out window ventilators are modular designs, can be used flexibly and can be optically and harmoniously integrated.
