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...
While at first, it may seem as if simply replacing your HEPA filter with a ULPA filter is a good idea, we hope you now understand why that wouldn't work. A filtration system designed for a certain airflow must be designed to anticipate the filter element's resistance to flow, and a ...
FFU(全称:Fan Filter Units,风机滤器机组) 风机滤器机组是将风机和过滤器(高效过滤器(HEPA)或超高效过滤器(ULPA))组合在一起构成自身提供动力的末端净化设备。 确切地说,它是一种自带动力、具有过滤功效的模块化的末端送风装置。风机从FFU顶部将空气吸入并经HEPA过滤,过滤后的洁净空气在整个出风面以0.45m/s±20...
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...
EAF(全称:Exhaust Air Fan,排风机)HEPA(全称:High Efficiency Particulate Air Filter,高效过滤器)高效过滤器,是指达到 HEPA 标准的过滤网,对于 0.1 微米和 0.3 微米的有效率达到 99.998%。HEPA 网的特点是空气可以通过,但细小的微...
Diffusion: Very small particles, particularly those below 0.1 microns, collide with gas molecules, impeding their path through the filter and increasing the chance they'll be captured by interception or impaction. HEPA vs. Other Filters Not all air filters are created equal.Standard MERV filters, ...
