Description

Series LSD linear slot diffusers have a modern understated appearance, high air handling capacity and the ability to perform both supply and extract functions.


Linear slot diffusers are normally supplied complete with a specially adapted plenum box (side entry as standard) and brackets to suit. This not only connects the diffuser easily and effectively to ductwork, but also provides a discreet fixing method, avoiding any visible face fixings.  


Features and benefits:

  • Suitable for both extract and supply functions.
  • Can be supplied in multiple sections to create runs of unlimited length.
  • Plaster-in variant available.
  • Simple and effective alignment method for multiple section units.
  • Slot boxes for connection to ductwork available.
  • Available with either a standard flanged or plaster-in frame.
  • Choice of one to eight slots.
  • A full range of options including internal deflectors to enable throw direction adjustment, end caps and polyester powder coating to any RAL or BS colour.
