Product Description & Applications

The ZIEHL-ABEGG ZN056-6IL.BD.V5P4 is a high-performance EC axial fan component for installation in refrigeration, air conditioning, ventilation and industrial systems. The combination of the aerodynamically optimized ZAplus impeller and ECblue drive delivers high airflow while minimizing energy consumption.

The fan is designed for conveying clean, non-aggressive and non-explosive air. Thanks to the integrated ECblue basic controller, the fan speed can be controlled either via a 0–10 V or PWM control input or through the integrated Modbus RS-485 interface, allowing seamless integration into modern building management systems.

Note: This fan is an industrial component and not a ready-to-use ventilation unit. Installation and electrical connection must be carried out in accordance with the manufacturer's instructions and all applicable regulations.
