什么是ULPA?——简述ULPA过滤器(Ultra Low Penetration Air Filter)与HEPA过滤器(High efficiency particulate air Filter)的区别 从英文名称的扩展来看,ULPA过滤器、HEPA过滤器(高效过滤器),在国内空气过滤器行业,一般延用欧标和美标的叫法,H11以上(H11-U17)的材料就被称为HEPA滤网, 从上图对应的过滤效率可以看出...
Ultra-Low Particulate Air Filter (ULPA Filter) - removes smaller particles sizes between 0.1-0.3 microns with an efficiency of 99.999%. What are the similarities of HEPA and ULPA Filters? Filtration Process Both HEPA and ULPA Filters are designed to trap particulate impurities from an airflow by...
ULPA vs. HEPA Filter SystemsOK, but if ULPA is better than HEPA at capturing more and smaller particles (such as tiny viruses), why are we still using HEPA?It's because, in this case, "better" is only true in a narrowly-defined sense. While ULPA filters collect more particles in ...
SUMMARY This paper compares the difference of HEPA/ULPA filter test standards between America and Europe from test procedures, aerosol types and its size, to air filter classification. Both of them adopt MPPS method as their trend. According to EN1822, it is recommended to combine the test rigs...
本欧洲标准适用于高效微粒空气过滤器(EPA);用于通风和空调领域以及技术流程的高效颗粒空气过滤器(HEPA)和超低渗透空气过滤器(ULPA);例如,用于洁净室技术或制药行业的应用。它建立了基于使用液体测试气溶胶的颗粒计数方法确定效率的程序;并允许根据效率对这些过滤器进行标准化分类。 EN 1822 系列的这一部分涉及测量过滤...
