TDV-SilentAIR

Application

• Type TDV-SilentAIR 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)
• Individually adjustable air control blades to meet individual requirements
• For variable and constant volume flows
• For supply air to room air temperature differences from –21.6 to +18 °F
• For room heights up to 13.3 ft (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

• Very low sound power level, ideal for comfort zones
• Individually manually adjustable air control blades
• For all types of ceiling systems, and with an extended border also suitable for freely suspended installation
• Black or white air control blades

Nominal sizes

• 12, 16, 20, 24
