Intelligent window ventilators
An all-round healthy indoor environment improves your well-being.
Demand-controlled ventilation plays a central role here.
Our AERO window ventilators offer particularly versatile solutions

almost invisibly in and around the window.
Their capabilities range from effective sound absorption up
