空气过滤器的分类

空气过滤器的分类

空气过滤器可以从多个维度进行分类，最常见的包括按过滤效率、结构形式和采用的过滤介质或原理。按过滤效率等级 (By Efficiency Rating): 这是最重要和最常用的分类方法，直接关系到过滤器能去除多小颗粒物的能力。不同国家和地区有不同的分级标准（具体标准见下一节），但大致可分为以下等级：初效过滤器 (Primary / Pre-filters): 典型效率范围: 大致对应旧欧标 EN...

工作原理

工作原理

空气过滤器去除污染物的原理并非单一机制作用的结果，而是多种物理（有时包括化学或静电）效应协同工作的结果。其主导机制取决于污染物的性质（尤其是颗粒大小）和气流条件。过滤机制 (Filtration Mechanisms) - 主要针对颗粒物: 拦截 (Interception): 原理: 当空气携带微小颗粒流经滤材时，颗粒会跟随气流的流线运动。如果某条流线距离滤材纤维表面的距离小于颗粒自身的半径，...
