Application

Application

  • Type QLV displacement flow diffusers are used as supply air units for industrial and comfort zones
  • Attractive design element for building owners and architects with demanding aesthetic requirements
  • Floor-standing installation on walls or in corners
  • Low-velocity airflow, causing only low levels of induction and resulting in low-turbulence displacement ventilation.
  • Excellent air quality in the occupied zone
  • Draught-free and economical ventilation and air conditioning also of larger internal spaces such as shop floors or auditoriums, with several displacement flow diffusers in a regular arrangement
  • For variable and constant volume flows
  • For supply air to room air temperature differences from –6 to –1 K

Special characteristics

  • Three-way or five-way air discharge
  • Duct connection at the top or bottom
  • Optional damper blade for volume flow rate balancing

Nominal sizes

  • ∅D: 160, 200, 250, 315, 400, 500, 630 mm
  • H: 500, 600, 800, 1000, 1250, 1500, 1750 mm
