Against the backdrop of global carbon neutrality goals and increasingly pressing energy challenges, optimizing the energy consumption of HVAC systems has become a focal point for enterprises and building operators. With energy costs continuing to rise and governments intensifying carbon emission reg
The difference between AC and EC centrifugal fans is not simply a matter of motor type. AC fans represent a mature and reliable conventional solution, while EC fans place greater emphasis on operating efficiency, control flexibility, and long-term cost performance. As energy efficiency, industrial cost control, and intelligent system management become more important, fan selection is shifting from simply meeting airflow requirements to evaluating overall operating value.
In Ventilation and Purification, the FlowGrid grille has long been regarded as a "necessary but secondary" mechanical accessory. However, as building energy codes become stricter and indoor environmental quality requirements rise, fan noise has emerged as a core pain point affecting user experience and equipment selection.
