Ceiling swirl diffusers with square diffuser face for high rooms in comfort and industrial zones. For supply air only. Blades in diagonally opposed sections can be adjusted for air discharge from horizontal (0°) to vertical (90°). Horizontal air discharge with high induction. For freely suspended installation or for suspended ceilings of all types. Ready-to-install component which consists of the diffuser face with four equal blade arrays, a cross bar for fixing the actuator, a plenum box with side entry or top entry spigot, and suspension holes. The diffuser face is fixed to the plenum box with a screw. 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 VD ceiling swirl diffusers are used as supply air diffusers for high rooms in comfort and industrial zones
  • For production halls, gymnasiums, theatres and conference rooms as well as for large internal spaces in airports, railway stations and shopping centres
  • For mixed flow ventilation with different air patterns in heating and cooling modes
  • Horizontal swirling supply air discharge in cooling mode
  • The efficient swirl creates high induction levels, thereby rapidly reducing the temperature difference and airflow velocity
  • Angled or vertical air discharge in heating mode
  • For variable and constant volume flows
  • For supply air to room air temperature differences from –12 to +15 K
  • For room heights exceeding 3.8 m
  • With freely suspended installation, an extended border supports the horizontal air discharge in cooling mode

Special characteristics

  • With adjustable air control blades for high rooms
  • The air pattern can be adjusted manually or with an actuator
  • Horizontal or vertical duct connection

Nominal sizes

  • 425, 600, 775, 1050
