General information

Application
  • Swirl diffusers for supply air and extract air in comfort zones
  • A design feature for building owners and architects with high demands on architecture and design
  • Horizontal swirling supply air discharge for mixing ventilation
  • Efficient swirling airflow with high induction for rapid reduction of temperature differences and air velocity (supply air)
  • For constant and variable volume flows
  • For supply air to room air temperature differences of -12 – +10 K
  • For rooms with heights up to 4 m (underside of suspended ceiling)
  • For all types of ceiling systems
    • Smaller swirl diffusers suitable for 600 or 625 ceiling grids
  • With an extended border also suitable for freely suspended installation (supply air variant)

Special characteristics
  • High induction results in a rapid reduction of the supply air to room air temperature difference and airflow velocity
  • For all ceiling systems, and with an extended border also suitable for freely suspended installation
  • Smaller swirl diffusers suitable for 600 or 625 ceiling grids
  • Horizontal and vertical spigots
  • Very high room air change rates possible thanks to row arrangement with a minimum centre-to-centre spacing of 0.9 m

Nominal sizes

  • 300, 400, 500, 600, 625
