Slot diffusers with individually manually adjustable air control elements and an aesthetically shaped face section with one slot, for one­way horizontal, alternating horizontal or alternating angled air discharge. For supply air or extract air. For installation into suspended ceilings, particularly into panelled ceilings with standard 16 mm gaps. Ready­to­install component which consists of the diffuser face with individually adjustable black or white air control elements, and of a plenum box with side entry spigot and suspension lugs. Spigot suitable for circular ducts to EN 1506 or EN 13180. Sound power level of the air­regenerated noise measured according to EN ISO 5135.

Application

Application

  • Type VSD15 slot diffusers are used as supply air or extract air devices in comfort zones
  • Air discharge is one-way or alternating horizontal, or alternating angled; turbulent flow (mixed flow ventilation)
  • High induction results in a rapid reduction of the temperature difference and airflow velocity (supply air variant)
  • For variable and constant volume flows
  • For supply air to room air temperature differences from –10 to +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For suspended ceilings; suitable for restricted ceiling voids due to the low overall height of the plenum box
  • Ideal for suspended panelled ceilings with standard 16 mm gaps
  • Suitable for continuous linear arrangement

Special characteristics

  • Individually adjustable air control elements to meet individual local requirements
