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, 400, 500, 600, 625



Variants

  • TDF-SA-Q: Square diffuser face

  • TDF-SA-R: Circular diffuser face

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

  • Square plenum boxes and plenum boxes with vertical spigot: Spigot made of galvanised sheet steel

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

  • Lip seal made of Evoprene

  • Diffuser face powder-coated, RAL 9010, pure white

  • P1: Powder-coated, RAL Classic colour
