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. Type AIRNAMIC ceiling swirl diffusers have fixed blades with three-dimensionally profiled contours. This allows for high volume flow rates and low sound power levels. The supply air to room air temperature difference can range from -12 to +10 K. A damper blade simplifies volume flow rate balancing for commissioning. To give rooms an aesthetic, uniform look, Type AIRNAMIC diffusers may also be used for extract air. There is then no equalising element.

Nominal sizes	160, 250, 300, 400, 600, 625 mm
minimum volume flow rate, with Δtz = -6 K	5 – 76 l/s or 16 – 274 m³/h
maximum volume flow rate, at LWA ≅ 50 dB(A)	44 – 385 l/s or 159 – 1386 m³/h
Supply air to room air temperature difference	-12 – 10 K

Specification text

Ceiling swirl diffusers with square or circular diffuser face, for comfort zones with particularly demanding requirements of aesthetics and design. Supply air and extract air variants. Excellent aerodynamic and acoustic function due to air control blades with optimised aerofoil contours, for horizontal swirling air discharge, creating high levels of induction. For installation into all types of suspended ceilings. Ready-to-install component that consists of a diffuser face with either a plenum box or a spigot. Plenum box with horizontal spigot, cross bar and either drilled holes or suspension lugs, with a damper blade for volume flow rate balancing and a lip seal on the spigot, supply air spigot with equalising element. Alternatively, spigot for nominal sizes 160 and 250 for the direct connection to ductwork, diffuser face fixing without any tools. The diffuser face can be fixed to the cross bar with a central screw, concealed with a cap. Spigots are suitable for ducting according to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Special characteristics
