The acoustic diffusers type YAD and YAZ reduce noise, recover static pressure and deliver uniform airflows in comfort and industrial installations. The YAD is available for all sizes of NovAx and ZerAx axial fans.
The YAZ is available for fan size Ø1800 only.
The profile of the YAD is round, the shape is conical and versions with or without core are available for high-frequency or standard sound attenuation.
The profile of the YAZ is octagonal, conical in shape and without core for standard sound attenuation.
