Description and function

Air transfer units play an important role in optimizing indoor comfort by facilitating the movement of air between neighboring spaces, such as residential, hotel, or office rooms, while ensuring a good system balance, low resistance, and sound levels. Airvent’s slim and compact air transfer unit, ÖLR, is an optimal solution designed to address these needs. The ÖLR’s emphasis on aesthetics, functionality, noise reduction, and ease of installation ensures effective integration into a variety of ventilation systems, making it a valuable component in achieving an optimal indoor environment.

The ÖLR comes standard with two identical pressed front plates in a circular design, featuring sound absorbing insulation within each plate. The diffusers are designed with a slim profile, ensuring that each set seamlessly blends into diverse architectural settings. Supplied as standard with bayonet-type mounting frames, each diffuser is fastened on both sides of a wall dividing two rooms, positioned across from each other just above the doors, allowing air to move freely through the opening in the wall and between spaces.
