Design ceiling swirl diffusers with perforated square 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 fixed air control blades 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, a top entry spigot or a plenum box with equalising element, a side entry spigot, and suspension lugs. 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 DCS ceiling swirl diffusers are preferably used as supply air diffusers for comfort and industrial zones
  • Perfect integration with suspended perforated sheet metal ceilings
  • 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 –12 to +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For T-bar ceilings

Special characteristics

  • Horizontal air discharge creating high induction levels
  • Design variants with perforated square or circular diffuser face style
  • For T-bar ceilings
  • Horizontal or vertical duct connection

Nominal sizes

  • Diffuser face: 593, 598, 618, 623
  • Swirl diffuser: 125, 160, 200, 250, 315, 400
