Functional description

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 may 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	300, 400, 600, 625 mm
Minimum volume flow rate, with Δt_Z = –6 K	13 – 76 l/s or 47 – 274 m³/h
Maximum volume flow rate, with L_WA ≅ 50 dB(A)	95 – 385 l/s or 342 – 1386 m³/h
Supply air to room air temperature difference	–12 to +10 K

Quick sizing tables provide a good overview of the volume flow rates and 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 our Easy Product Finder design programme.

Innovation

Type AIRNAMIC swirl diffusers meet the most demanding requirements of technical function, comfort, and design.

The unique design of the air control blades, a specially developed equalising element, and the innovative plenum box result in high volume flow rates, a low sound power level and low differential pressure.

The air control blades have three-dimensionally profiled contours to create an efficient swirl. As a consequence, the air velocities and temperature differences in the occupied zone are very low, and the level of comfort is excellent.

The production of these unusually contoured blades is only possible by the use of high-quality plastics and by applying innovative production technology.

The exceptionally aesthetic air control blades allow for perfect architectural integration of the circular or square swirl diffuser and therefore make for an important design element for building owners and architects.

A spigot with double lip seal provides a low-leakage connection of the plenum box to the ducting, and a lockable damper blade for volume flow rate balancing simplifies commissioning.
