Active transfer passages: Ventilation through doors and walls

Connector fans, also called “active transfer passages”, enhance the benefits of mechanical ventilation. The elements are integrated into doors or walls, and blow air almost silently between corridors and rooms. The result is more efficient and more purposeful ventilation.

Ventilation through the doors
Active transfer passages expand the function of the doors into a ventilation element. Increased air movements are noticeable only in the vicinity of closed doors. The area is optimally and adequately supplied with air. Active transfer passages indoors are especially suited for living areas and smaller commercial spaces.

Ventilation through the wall
If there is a need for larger quantities of air and even better noise values, active transfer passages can be integrated directly into walls. Whether with discreet covers in front or mounted entirely flush with the surface: Active transfer passages impress time and time again.
