Ceiling swirl diffusers allow the supply air from ventilation systems to flow into the room in a swirl pattern. The resulting airflow induces high levels of indoor air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling swirl diffusers enable large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall indoor ventilation, creating only low turbulence in the occupied zone. TROX INVISIBLE DIFFUSER (TID) are characterised by their unobtrusive or inconspicuous installation. The swirl unit required for the swirling air discharge is not visible from the room. The special shape of the discharge nozzle allows the swirl effect to be used even behind standard perforated metal ceiling tiles or factory-made perforated metal sheet fronts. Type TID ceiling swirl diffusers have fixed air control blades. Air distribution is horizontal, with an omni-directional flow. The supply air to room air temperature difference may range from –12 to +10 K. A damper element in the plenum box simplifies volume flow rate balancing for commissioning. To give rooms an aesthetic, uniform look, Type TID diffusers may also be used for extract air.

Nominal diameter125, 160, 200, 250, 315 mm
Supply air to room air temperature difference-12 – +10 K

The quick sizing table gives a good overview of the possible volume flow rates and the corresponding sound power levels and differential pressure levels for the combinations with the different perforated sheet metal fronts. 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 program. The quick sizing tables for various sample perforations are listed below:

Specification text

Ceiling swirl diffusers for invisible or inconspicuous installation behind standard metal ceiling tiles or factory-made perforated sheet metal fronts. The ceiling swirl diffuser is suitable for comfort and industrial zones and is installed as a supply or extract air diffuser in the suspended ceiling. The swirling element with fixed air control blades enable a horizontal swirling supply air discharge creating high induction levels so that the airflow velocities and temperature differences are quickly reduced. The special shape of the discharge nozzle allows the swirl diffuser to be used behind standard perforated metal ceiling tiles. To ensure a visually uniform ceiling appearance, the standard metal ceiling tiles must not be thicker than 1.0 mm. Preferred thickness: ≤ 0.7 mm. The ceiling swirl diffuser can be combined with ceilings of all types using a factory-fitted perforated sheet metal front. The ready-to-install functional unit consists of the specially moulded discharge nozzle, the swirl element with fixed air control blades and spigot and is always coated black. The functional unit can be connected directly to the on-site air duct system or combined with a plenum box from the AK-Uni series. In case of a vertical connection, suspension lugs are provided for on-site fixing to the spigot. The plenum box has drilled holes for on-site fixing. All spigots are suitable for ducts according to EN 1506 or EN 13180. The sound power level of the air-regenerated noise is measured according to EN ISO 5135.

  • Visually inconspicuous or non-visible functional unit
  • Functional unit consists of discharge nozzle, swirl element and spigot
  • For a visually uniform ceiling appearance: Installation behind standard perforated metal ceiling panel provided by the customer (free cross-section ≥ 15 %)
