Staircase diffuser Type SZD

  • Available with round or quadratic perforated plate front
  • Front mounting option: The diffuser is screw fixed to the front side of the step and is then fastened to the diffuser perforated plate
  • Insertion into ductwork option: The entire diffuser is inserted into a duct having an inside diameter of 125 mm and fastened by tightening the middle screw. This enables an easy, quick and extremely inexpensive mounting procedure


The swirling jets leave the diffuser with radial action and flow towards the floor. The air velocity and temperature difference is rapidly reduced. This guarantees draughtfree conditions at a short distance between the diffuser and legs of the audience
