Swirl Deflector
The swirl deflector installed at the back of the nozzle diffuser generates a rotary motion that increases induction and reduces the throw of the diffuser by 40% and is particularly suitable for the supply of high air flow rates in medium-sized rooms as it prevents sensitive air currents in the occupied area.Description Photo
