VDL- HIGH EXPOSURE SWIRL DIFFUSERS DESCRIPTION: Ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. 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. Ceiling swirl diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone : Adjustable Blade (6-12 Blades) VDL-S: Fixed Blade (12 Blades) MATERIAL :...
