With low sound power level for comfort and industrial zones, with fixed air control blades.

Circular and square ceiling swirl diffusers
■ Nominal sizes 125, 160, 200, 250, 315, 400
■ Volume flow rate range 4 – 330 l/s or 14 – 1188 m³/h
■ Diffuser face made of galvanised sheet steel, powder-coated,
or of aluminium (depending on variant)
■ For supply and extract air
■ For variable and constant volume flows
■ For all types of ceiling systems
■ With discharge nozzle ideal for cooling in case of freely suspended installation
■ High induction results in a rapid reduction of temperature differences
and airflow velocities
■ Air change rates of up to 35 per hour can be achieved by arranging several
diffusers in a row with a minimum pitch of 0.9 m (centre line to centre line)
■ Ideal for comfort zones
