  • Nominal sizes: 100, 125, 160, 200, 250, 315 and 400 mm
  • Volume flow range: 15 – 400 l/s or 54 – 1440 m³/h
  • Visible parts made of aluminium
  •  For constant and variable volume flows
  • Low sound power level due to aerodynamic, optimised nozzle contour
  • Discharge angle can be adjusted manually or with an actuator
  • Quick, easy and concealed fixing

Optional equipment and accessories
  • Exposed surface in RAL CLASSIC colours
  • Circular spigot
  • Connecting piece for circular and rectangular ducts
  • Actuators for adjusting the discharge angle

General information 

Application
  • Jet nozzles as supply air diffusers, with a long throw distance
  • For factories, gymnasiums, theatres and conference rooms as well as for large internal spaces in airports, railway stations and shopping centres
  • Attractive design element for building owners and architects with demanding aesthetic requirements
  • For supply air to room air temperature differences from -12 – +20 K
  • Adjustable discharge angle from -30 – +30°, for switching between heating and cooling mode
  • Connection options:
    • Push-fit connection onto circular air ducts (pipe connection)
    • As a direct branch from circular and rectangular air ducts
    • For installation in walls or bulkheads

Special characteristics
  • High discharge momentum, hence large penetration depth in heating mode
  • Optimised nozzle contours
  • Fixed and adjustable variants
  • Discharge angle can be adjusted from -30° – +30°, either manually or with an actuator
  • Electric actuator optional
