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. Leveraging its R&D and testing center at Suzhou BLAUBERG Motor Technology Co., Ltd., BLAUBERG has systematically optimized both aerodynamics and acoustics, and officially launched its noise-reducing FlowGrid grille. This product not only breaks away from the traditional "smooth grille + simple flow guidance" design paradigm but also establishes a clear technical path between bionics and real-world test data.
