ER71C-4DN.L7.1R 130559/0Z41 is a 400 VAC centrifugal fan for data centers, air-conditioning systems, packaging machinery. Its main supplied feature is ECblue motor and integrated-control technology referenced for this model. It also lists a 710 mm size specified in the upload data. Review duct connection for motor selection.
Designed for renewable-energy and power-conversion equipment, ER71C-4DN.L7.1R 130559/0Z41 combines ZIEHL-ABEGG engineering with an AC centrifugal fan format suited to OEM integration. The design supports stable thermal management in compact equipment layouts.
A free-running backward-curved impeller supports high static-pressure capability without a conventional scroll. The aerodynamic wheel and diffuser concept are designed for efficient airflow, stable rotation and favorable acoustic behavior.
OEM engineers should verify the complete ER71C-4DN.L7.1R 130559/0Z41 code, mounting arrangement, airflow direction and electrical interface before release. This gives purchasing teams a traceable basis for repeat orders and service replacement.
For purchasing teams, the exact model reference supports controlled sourcing and service identification. For equipment serving HVAC, outdoor air-conditioning and ventilation equipment, ZIEHL-ABEGG ER71C-4DN.L7.1R 130559/0Z41 moves conditioned or exhaust air through the intended system path.
For data-center cooling and dry-cooler systems, the ER71C-4DN.L7.1R 130559/0Z41 AC centrifugal fan helps cooling plant maintain predictable conditions for ICT equipment. Thermal consistency matters because changing loads can shift where heat collects inside the system.
Used within packaging machinery, production equipment and automation systems, ER71C-4DN.L7.1R 130559/0Z41 ventilates production machinery and automation enclosures during repeated cycles. System testing can confirm that the selected unit delivers the required cooling role after integration.
For equipment serving rail vehicles and trackside equipment, ZIEHL-ABEGG ER71C-4DN.L7.1R 130559/0Z41 supports ventilation where compact packaging and long duty cycles limit passive cooling. It gives project teams a clear basis for system testing, bill-of-material control and future replacement.
Check supply voltage, controller signals, blocked airflow, contamination, abnormal noise, rotation, and the equipment operating point before replacing the unit.
The matched source highlights ECblue motor and integrated-control technology referenced for this model. Compare that point together with the listed electrical and dimensional data.
The series information indicates controllability, but whether a separate controller is needed depends on the exact motor and integrated electronics.
It may be evaluated for high-reliability cooling using the supplied parameters, but duty cycle, redundancy, ambient limits, and protection must be confirmed at system level.
Available performance data includes 21700 m³/h airflow, 1906 Pa pressure, 17093 W input. Obtain the full curve when system resistance or part-load behavior matters.
The matched series documentation highlights efficiency-related design. Calculate savings from the actual operating point, control strategy, service interval, and purchase cost.
