Product data sheet General information Function Technical data Quick sizing Specification text Order code Variants Dimensions Product details Nomenclature General information Application ▪ Ceiling swirl diffusers are used as supply air or extract air diffusers for comfort zones ▪ Attractive design element for building owners and architects with demanding aesthetic requirements ▪ Horizontal swirling supply air discharge for mixed flow ventilation ▪ The efficient swirl creates high induction levels, thereby rapidly reducing the temperature difference and airflow velocity (supply air variant)...

Product data sheet Function 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....

Product data sheet Horizontal omni directional air discharge

Product data sheet Technical data Nominal sizes Minimum volume flow rate, with Δtz = -6 K Maximum volume flow rate, with LWA ≅ 50 dB(A) Supply air to room air temperature difference Quick sizing The quick sizing tables give a good overview of the volume flow rates and the corresponding sound power levels and differential pressures. The minimum volume flow rates apply to a supply air to room air temperature difference of -6 K. The maximum volume flow rates apply to a sound power level of approx. 50 dB (A) with damper blade position 0°. Exact values for all parameters can be determined with...
