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)
  • For variable and constant volume flows
  • For supply air to room air temperature differences from -12 – +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For all types of ceiling systems
  • With an extended border also suitable for freely suspended installation (supply air variant)



Special features

  • High induction results in a rapid reduction of the supply air to room air temperature difference and airflow velocity





  • For all types of ceiling systems, and with an extended border also suitable for freely suspended installation




  • Horizontal or vertical duct connection




  • Very high room air change rate possible thanks to row arrangement with a minimum pitch distance of 0.9 m



Nominal sizes

  • 300 × 8, 400 × 16, 500 × 24, 600 × 24, 600 × 48, 625 × 24, 625 × 54, 825 × 72



Variants

  • VDW-Q: Square diffuser face
  • VDW-R: Circular diffuser face
  • VDW-*-Z: Supply air
  • VDW-*-A: Extract air

  • V: Vertical duct connection



Accessories



Lip seal

  • For circular plenum boxes with horizontal connection spigot, the lip seal is only available in combination with the flow adjustment damper. Otherwise, it can always be selected optionally.



Attachments

  • M: Damper element for volume flow rate balancing




  • MN: Pressure tap and cord-operated damper unit for volume flow rate balancing with the diffuser face in place (only possible with square plenum box)



Construction features

  • Spigot suitable for circular ducts to EN 1506 or EN 13180




Square plenum boxes and plenum boxes with vertical connection

  • With spigot made of galvanised sheet steel
  • Groove only available if lip density characteristic has been selected

 





Circular plenum boxes with horizontal spigot

  • Spigot in black ABS material
  • Groove for installation of the lip seal always available
  • Later retrofitting of the lip seal possible




  • Plenum box for supply air, with an optimised equalising element that ensures a uniform airflow through the diffuser face





  • Simple installation of the diffuser face due to central fixing screw with decorative cap




Materials and surfaces



  • Grille face made of galvanised sheet steel




  • Q; R: Plenum box made of galvanised sheet steel including galvanised sheet steel cross bar to support the diffuser face




  • Plenum boxes with vertical connection and square plenum boxes with horizontal connection: for supply air always with galvanised perforated plate for air distribution




  • Circular plenum boxes with horizontal spigot: Equipped as a plenum box for supply air with an equalising element made of polyester

  • Circular plenum boxes with horizontal spigot: Spigot made of black ABS, according to UL94, V0 flame retardant




  • Air control blades made of plastic, UL 94, V-0, flame retardant




  • Lip seal made of Evoprene




  • Diffuser face coated RAL 9010, pure white



  • P1: Powder-coated, RAL Classic colour


  • Air control blades for supply air similar to RAL 9005, black; extract air variant without air control blades
  • Q11: Air control blades for extract air similar to RAL 9005, black




  • Q21: Air control blades for supply air and extract air similar to RAL 9010, white



Standards and guidelines

  • Sound power level of the air-regenerated noise measured according to EN ISO 5135



Maintenance

  • Low maintenance as construction and materials are not subject to wear




  • Inspection and cleaning to VDI 6022
