Description

  • Frame is fabricated from high quality extruded aluminium profiles with the advantages of corrosion resistance and rigidity.
  • Perforated panel is fixed to the frame by screws. Panel can be removed easily by loosening the screws.
  • For supply air diffusers, perforated sheet is slightly lowered below the center line. This arrangement provides improved horizontal airflow.
  • Different types of internal cores can be fixed inside the perforated panel as option. Core is fixed to the frame with aluminium pins loaded with steel springs. Core can be easily removable and interchangeable to allow for maximum flexibility in installation and maintenance.
