Description and manufacturing
VDL swirl diffusers are used in air conditioning, ventilation and heating systems. They create a swirling air supply for good mixing with the room air. The air stream leaving the diffuser achieves high induction ratios, so the air velocity drops quickly and the temperature difference between the supply air and the room air is rapidly equalised.
They are used for high airflows with a large temperature difference between room air and supply air, from -10°C to +15°C. The blades rotate about their own axis, resulting in mixing of the air streams in the comfort zones, with good distribution of air jets throughout the room and only slight turbulence in the occupied zone. These diffusers are used in rooms with ceiling heights of 4 metres and above.
DESIGN AND MATERIALS
Material: the diffuser body and blades are made of aluminium.
Colour: standard white RAL 9010; other RAL colours must be agreed in advance.
MANUFACTURE
Diffusers of this series are available in standard diameters only: d-200, d-250, d-315, d-400; for larger sizes a different diffuser type, DVA, is available.
