Diffusers are designed for low and medium-pressure ventilation systems. The diffusers provide swirl air supply and are particularly recommended for premises from 2 to 5 m in height.

NWM is equipped with still blades, which form swirl air flow. Head panel of the diffuser can be shaped round or square. NWM is made from steel powder coated with RAL9010. On request it is possible to make it out of stainless steel or coat it to different RAL color.
