High Exposure Diffusers

Ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflowinduces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature differencebetween supply air and room air. Ceiling swirl diffusers allow for large volume flow rates. The result is a mixedflow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in theoccupied zone

Typical Applications


Type VDL ceiling swirl diffusers have adjustable air control blades. Different air patterns allow for cooling orheating mode, or for the adjustment to varying loads. Horizontal air discharge is omni directional. Vertical airdischarge is possible in heating mode. The supply air to room air temperature difference may range from –12 to+15 K.

Nominal sizes 315, 400, 630, 800
Volume flow rate range 65 – 1080 l/s or 234 – 3888 m³/h
