核心优势 Core Advantages
-
精细化过滤设计
采用梯度密度过滤材质，外层预过滤网可拦截毛发、灰尘等大颗粒污染物，内层高密度纤维层则能捕捉细微悬浮物，实现分级过滤效果。
Gradient-density filtration materials are adopted, with an outer pre-filter screen intercepting large particles such as hair and dust, while the inner high-density fiber layer captures fine suspended particles, achieving multi-stage filtration.
-
低风阻性能优化
蜂窝状支撑结构设计在保证过滤精度的同时，减少空气通过阻力，使通风设备保持高效运行状态，降低能源损耗。
Honeycomb support structure design reduces airflow resistance while maintaining filtration accuracy, enabling ventilation equipment to operate efficiently with lower energy consumption.
