Design ceiling swirl diffusers with square or circular diffuser face, for comfort zones with particularly demanding requirements of aesthetics and design. Supply air and extract air variants. Excellent aerodynamic and acoustic function due to swirl unit for horizontal swirling air discharge, creating high levels of induction. For installation into all types of suspended ceilings. Ready-to-install component which consists of the diffuser face, swirl unit, plenum box with equalising element, side entry or top entry spigot, and suspension holes or suspension lugs. The diffuser face is fixed to the cross bar with a central screw. Spigot suitable for ducts to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Application

Application

  • Type ADD 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 to +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For all types of ceiling systems

Special characteristics

  • For the creative design of ceilings in comfort zones
  • Diffuser faces in many different designs
  • For all types of ceiling systems, and with an extended border also suitable for freely suspended installation
  • Horizontal or vertical duct connection

Nominal sizes

  • 250, 300, 400, 450, 500, 600, 625
