Circular air diffuser AIRNAMIC

squareceilingfixed

Circular and square ceiling swirl diffusers with fixed air control blades, for high volume flow rates at low sound power levels and low differential pressure due to innovative polymer technology Nominal sizes 160, 250, 300, 400, 600, 625 Plastic diffuser face with overlapping, three-dimensionally contoured blades, for the most efficient swirl and high induction For supply and extract air For variable and constant volume flows For all types of ceiling systems, and with an extended border also suitable for freely suspended installation Diffuser face with gently sloped, flat border – only 3 mm high Plenum box with acoustically optimised and lockable damper blade Spigot for nominal sizes 160 and 250 allows for quick, simple and direct connection to the ductwork Diffuser face with bayonet fixing (no tools required) available for nominal size 160 or 250 and with a spigot Exposed diffuser face available in RAL CLASSIC colours 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.
