TDF-SilentAIR

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
