HEPA (High-Efficiency ParticulateAir Filter).Tebchaws Asmeskas tau tsim ib pab pawg tsim kho tshwj xeeb hauv xyoo 1942 thiab tsim cov khoom sib xyaw ntawm cov ntoo fiber ntau, asbestos, thiab paj rwb.Nws qhov kev ua haujlwm pom tau mus txog 99.96%, uas yog daim ntawv embryonic ntawm HEPA tam sim no.Tom qab ntawd, iav fiber ntau hybrid lim ntawv tau tsim thiab siv hauv atomic technology.Thaum kawg nws tau txiav txim siab tias cov khoom siv cuab yeej cuab tam ntawm ntau tshaj 99.97% rau 0.3μm hais, thiab nws tau raug hu ua HEPA lim.Nyob rau lub sijhawm ntawd, cov khoom siv lim tau ua los ntawm cellulose, tab sis cov khoom muaj teeb meem ntawm cov hluav taws tsis zoo thiab hygroscopicity.Thaum lub sijhawm, asbestos kuj tseem siv los ua cov khoom siv lim dej, tab sis nws yuav tsim cov tshuaj carcinogenic, yog li cov khoom siv lim dej ntawm cov lim dej ua haujlwm siab tam sim no feem ntau yog siv los ntawm iav fiber tam sim no.
ULPA (Ultra Low Penetration Cua Lim).Nrog rau txoj kev loj hlob ntawm ultra-scale integrated circuits, cov neeg tau tsim ib tug ultra-high efficiency lim rau 0.1μm hais (cov plua plav qhov chaw yog tseem DOP), thiab nws pom efficiency tau mus txog ntau tshaj 99.99995%.Nws tau hu ua ULPA lim.Piv nrog HEPA, ULPA muaj cov qauv kev sib cog lus ntau dua thiab ua kom pom kev zoo dua.ULPA feem ntau yog siv hauv kev lag luam hluav taws xob rau lub sijhawm tam sim no, thiab tsis muaj ntawv ceeb toom ntawm cov ntawv thov hauv lubkws tshuaj thiab kho mob sectors.
