Frequently Asked Questions (FAQ)
What voltage options are available for these fan motors?
All motor models in this series support three voltage configurations: 380V, 660V, and 1140V, making them suitable for a wide range of industrial power supply environments.
How does the 100% speed control feature help reduce energy consumption?
The speed control system allows precise adjustment of air volume output to match actual operating requirements. By avoiding unnecessary full-speed operation, it significantly reduces power consumption and lowers overall operating costs.
What is the noise level of these fans during operation?
All models in this series maintain an A-weighted sound pressure level of 30 dB(A), achieved through bionic blade design with serrated trailing edges and specialized blade tips that effectively minimize operational noise.
What are the main advantages of the external rotor motor design?
The external rotor motor design provides a compact overall structure, superior heat dissipation performance, and high operational efficiency. The external bearing configuration further improves thermal management, extends the motor's service life, and makes routine maintenance easier.
What industries and applications are these fans suitable for?
These fans are widely used in industrial ventilation, mining, tunnel ventilation, HVAC systems, manufacturing facilities, and other environments that require reliable and efficient air movement with precise volume control.
What is the maximum total pressure efficiency these fans can achieve?
All models in this series achieve a maximum total pressure efficiency of 75%, which is made possible by the optimized aerodynamic blade design featuring spatially twisted structures and large-angle bending configurations.
