φ520mm-E001/E002 EC Backward-curved Centrifugal Fan

[ High Efficiency ] Aluminum alloy impeller optimized by ternary flow CFD fluid simulation technology, reasonably designed flow runner combined with ultra-efficient EC motor create the high efficiency of the fan.

[ Low Noise ] The designer closely combines aerodynamics and sound source, and makes the blade angle and blade pattern fully adapt to the ternary flow field, which always ensures lower noise at the same air volume.

[ High Reliability ] Motors have IP54 waterproof and dust proof protection, F class insulation, and been tested for 3 months of 60℃ high temperature test and 40,000 hours of life test, which ensure worse-free quality.

[ Accurate Intelligent Control ] The fan adopts efficient EC motor and supports various control modes such as 0~10V / PWM / RS485 to accurately meet the ventilation needs of different period of time.

[ Wide Application ] The products is used wherever outstanding performance is required, for example, IDC small cabinet, high voltage inverter cabinet, energy storage charging pile, commercial air conditioning, rail transit and more.

[ Variety of Models ] Available in dimensions of : 280mm，320mm，355mm，400mm，450mm，520mm, 560mm, 630mm, this allows for air flow rates of up to 20100m3/h and static pressure of up to 1500Pa.
