Description
The Ziehl-Abegg ZN071-SDL.6F.V7P1 is a high-performance, 710 mm external-rotor axial cooling fan engineered specifically for demanding commercial refrigeration, air conditioning, and industrial process cooling systems. Built with Ziehl-Abegg Original Engineering standards, this fan combines a bionic sickle-blade aerodynamic profile with an integrated 6-pole, three-phase external rotor motor. The direct-drive integration eliminates mechanical transmission losses, reduces overall unit depth, and minimizes vibrational wear, ensuring optimal acoustic efficiency and extended operational life in continuous-duty installations.

SYSTEM INTEGRATION AND TECHNICAL COMPATIBILITY
Designed for straightforward mechanical and electrical retrofit capability, the ZN071-SDL.6F.V7P1 delivers extensive Technical Compatibility with major OEM condensing units, chillers, and evaporators. The standardized mounting basket and perimeter bolt circle allow direct bolt-in replacement without sheet-metal alterations. The 400V three-phase winding supports both fixed-speed mains operation and variable speed regulation via voltage-reduction controllers or frequency converters equipped with all-pole sinusoidal filters. Integrated thermal contacts provide direct hardware-level trip signals to protect against phase imbalance, motor stall, and high-ambient overheating.
