Ideal for integration beneath steps and seats in theatres and other types of auditorium.

  • Air volume balancing is achieved via throttling segments arranged in the bottom plate of the air distribution box.
  • The supply air is introduced into the room at low velocity through a perforated panel
  • The diffuser’s front plate can easily be removed from the air distribution box and reinstalled without the need for any auxiliary tools, e.g. for cleaning or air volume balancing
