Slot diffusers with individually manually adjustable air control elements and an aesthetically shaped face section with one or two slots, for horizontal one-way, horizontal alternating or angled alternating air discharge. For supply air or extract air. For installation into suspended ceilings. Ready-to-install 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. Clamp fixing or concealed screw fixing Spigot suitable for circular ducts to EN1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Application

Application

  • Type VSD50 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
  • Suitable for continuous linear arrangement

Special characteristics

  • Individually adjustable air control elements to meet individual local requirements
  • High induction results in a rapid reduction of the temperature difference and airflow velocity
