Features

  • Highly inductive multi-stream discharge for draught-free comfort.
  • Multi-stream discharge direction manually adjustable via Allen key through diffuser face.
  • Allen key adjustment prevents inadvertent discharge direction adjustment (eg by cleaners).
  • Black plastic discharge elements (ABS, V0 fire rated) located behind the perforated discharge face break the airflow into a multitude of highly inductive individual air streams of differing discharge direction.
  • Adjustable air streams have four different discharge angles, with the outer angles flatter than inner ones, and each may be rotated to one of six discharge directions, ensuring highly inductive, broad dispersion of the supply air flow for draught-free air supply.
  • Perforated discharge face and frame of metal, painted to colour of choice.
