Ziehl-Abegg has globally launched ZAvblue, a centrifugal fan with superior air flow and compact design. The new impeller is up to 20% more efficient than standard products in the market. The bionic design of the impeller requires significantly less space. The required airflow can be generated with impellers that are one size smaller. The ZAvblue can be used for ventilation and exhaust (duct, tube and roof fans) for close control air handling units (cooling of data centres) as well as in clean rooms, heat pumps and compact air conditioning units. The product has been optimized to provide high efficiency even in confined spaces. The impeller design allows for minimal gap between fan and housing (pressure side panels close to the impeller). The bionic lightweight construction saves on the installation space while maintaining the strength. A patent application has been filed. Since the fan has standard connection sizes, customers can upgrade quickly to the new product. It can be fitted with both AC and EC motor using customized adapters, without significant modifications to the equipment. The impeller meets the latest EU energy saving requirements both with AC as well as ECblue motors. Ziehl-Abegg (Künzelsau, Baden-Württemberg, Germany) is a leader in the field of ventilation and drive technology and the associated control systems. For more information, visit www.ziehl-abegg.in
