  • Type VDW 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 elements to meet individual local requirements
  • 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

  • Air control blades can be adjusted individually manually for adjusting the air pattern
  • For all types of ceiling systems, and with an extended border also suitable for freely suspended installation
  • Black or white air control blades
  • Air change rates of up to 35 per hour can be achieved by arranging several diffusers in a row with a minimum pitch of 0.9 m (centre line to centre line)

Nominal sizes

  • 300 × 8, 400 × 16, 500 × 24, 600 × 24, 600 × 48, 625 × 24, 625 × 54, 825 × 72
