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 air control blades with optimised aerofoil contours, 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 and a plenum box, equalising element (only supply air variants), side entry spigot, cross bar, and suspension holes or suspension lugs. The diffuser face is fixed to the cross bar with a central screw, concealed by a decorative cap. Spigot suitable for ducts to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.

SPECIAL CHARACTERISTICS
- Plastic diffuser face with overlapping, three-dimensionally profiled blades, for the most efficient swirl and high induction

  • Application
  • Description

Application

  • Type AIRNAMIC 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
  • With an extended border also suitable for freely suspended installation (supply air variant)

Special characteristics

  • Plastic diffuser face with overlapping, three-dimensionally profiled blades, for the most efficient swirl and high induction
  • For all types of ceiling systems, and with an extended border also suitable for freely suspended installation
  • Diffuser face with gently sloped, flat border – only 3 mm high
  • Plenum box for supply air, with an optimised equalising element that ensures a uniform airflow through the diffuser face

Nominal sizes

  • Q: 300L, 300H, 600, 625
  • R: 400L, 400H, 600

Variants
