GRILLES AND DIFFUSERS


AIR DIFFUSION

 

Circular disc valves with manually adjustable annular gap. Supply air valves direct the air from air conditioning systems into the room. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.
