Description
ebm-papst W3G800-NS26-71 Reliable, industrial fan High Power Cooling EC Fan AC400V 50/60Hz 930RPM 1570W 2.5A Axial
The ebm-papst W3G800-NS26-71 is a high-efficiency 800mm axial fan featuring advanced GreenTech EC (Electronically Commutated) motor technology. Designed for critical thermal management in industrial environments, this unit combines an optimized aerodynamic blade profile with intelligent motor electronics to deliver high airflow volumes at reduced noise levels. The integrated EC controller allows for precise speed modulation via 0-10V or PWM signals, enabling demand-dependent operation that significantly lowers energy consumption compared to conventional AC asynchronous motors. This model is specifically engineered for installation in condensers, chillers, and heat exchangers where reliability and electrical efficiency are paramount. Its robust construction incorporates maintenance-free ball bearings, ensuring longevity even under continuous duty cycles in harsh ambient conditions. The W3G800-NS26-71 serves as a vital component for facility managers looking to optimize the PUE of data centers or the operational costs of large-scale refrigeration plants.
