The high efficiency particulate air (HEPA) filter is mainly used to capture dust particles and various suspended matters above 0.5μm. The air purifier is mainly composed of a filter element and a shell. The basic requirements for the filter are high filtration efficiency, low flow resistance, and long continuous usage for the sake of reducing later consumable costs.
Raws li cov khoom lim, nws yog hais txog lub lim cua. HEPA lim ua lub luag haujlwm tseem ceeb hauv kev lag luam huab cua huv.
Lub lim yuav siv cov ntaub ntawv ultrafine iav fiber ntau raws li cov khoom siv lim, offset ntawv thiab aluminium zaj duab xis raws li kev faib tawm. Nws yog glued nrog ntoo ncej aluminium alloy thiab ua los ntawm tshwj xeeb silicone roj hmab uas tsis muaj ntxhiab, thiab yuav tsis tawv, los yog tawg. Nws muaj cov tshuaj lom neeg ruaj khov thiab muaj zog tiv thaiv corrosion, tuaj yeem nqus tau kev ntxhov siab vim thermal expansion thiab contraction tsis tawg, me ntsis hardness, zoo elasticity rov qab. Txhua lub lim tau raug kuaj los ntawm cov nplaim hluav taws xob sodium thiab muaj cov yam ntxwv ntawm kev pom kev ua haujlwm siab, tsis muaj zog, thiab muaj plua plav loj.
Lub HEPA lim tuaj yeem siv dav hauv qhov hluav taws xob cua qhov hluav taws xob thaum kawg ntawm lub tshuab cua txias hauv cov plua plav-kev ntxuav dawb hauv kev lag luam xws li kho qhov muag hluav taws xob, LCD kua siv lead ua kua tsim, biomedicine, precision instruments, dej haus thiab zaub mov , thiab PCB luam ntawv. Lub HEPA lim thiab ULPA (ultra- cua nkag mus tsis tshua muaj) lim tag nrho tuaj yeem siv tom kawg ntawm chav huv. Raws li lawv cov qauv, lawv tuaj yeem muab faib ua: HEPA lim nrog muab faib, HEPA lim tsis muaj kev faib tawm, HEPA lim nrog cua ntim siab, thiab ULPA lim.
Kev faib tawm
HEPA lim tuaj yeem muab faib ua HEPA lim nrog muab faib, HEPA lim tsis muaj kev faib, V-BED HEPA lim, siab kub HEPA lim thiab kua flume HEPA lim.
HEPA lim tsis muaj kev faib tawm
The HEPA filter without partition replaces the aluminum foil of the HEPA filter with partition with hot melt adhesive to separate the filtering material. Because there is no partition, a 50mm thick non-partition filter can achieve the performance of a 150mm thick partition filter. The air volume of HEPA with 90mm thick frame can reach 1.3 times of SPAN 150mm thick standard resistance type and twice of SPAN 150mm thick standard resistance type under the same filter area and filtration efficiency. In general, the HEPA filter without partition can meet today's stringent requirements for various spaces, weights, and energy consumption of air purification industry.
HEPA lim nrog muab faib
Lub HEPA lim nrog muab faib yog ua los ntawm ultrafine fiber ntau li cov khoom siv lim dej thiab cov ntawv kraft zoo los ntawm cov txheej txheem kub dov los yog offset ntawv, aluminium ntawv ci raws li kev faib tawm. Nws yog glued nrog ntoo thav duab los yog aluminium alloy thav duab thiab ntawm qee qhov zoo xws li kev pom kev ua haujlwm siab thiab tsis muaj zog thiab huab cua loj. Lub HEPA lim nrog muab faib feem ntau yog siv ob npaug -sided coated tooj liab phaj daim ntawv raws li kev faib tawm los tiv thaiv kev sib cog lus nyob rau hauv qhov cuam tshuam ntawm qhov txias, cua sov, qhuav thiab ntub dej, yog li txo qhov tawg ntawm cov khoom. Nws yog qhov tsim nyog rau qib qis - theem tsis yog - unidirectional flow tej yaam num thiab ntau yam purification chaw thiab huv rhiav. Ntawm HEPA cov ntxaij lim dej nrog muab faib, txhuas muab faib lim feem ntau yog siv nyob rau hauv qhov kub thiab txias ib puag ncig, thaum daim ntawv muab faib lim siv rau hauv qhov chaw huv si. Cov huab cua ntim ntawm HEPA lim nrog kev faib tawm yog qhov siab, uas ua rau nws kub tsis kam.
V-BED HEPA lim
Nws muaj cov yam ntxwv ntawm cheeb tsam loj lim, tsis tshua muaj kev tiv thaiv thiab kev pab lub neej ntev thiab feem ntau yog siv rau hauv qhov cua tshuab. Nws tuaj yeem siv ua ntej - lim ntawm HEPA lim, yog li ua kom muaj txiaj ntsig zoo rau kev pab cuam lub neej ntawm HEPA lim.
Kub kub HEPA lim
The filter can be used in a high temperature environment of 250 degree 400 degree , and its filtration efficiency can reach as high as 99.99 percent @0.3μm.
D.O.P./P.S.L. Testing 95 percent ,99.99 percent at 0.3μm
Liquid Flume HEPA lim
Cov kua flume high efficiency particulate cua lim kuj tseem hu ua lub tank lim, thiab feem ntau yog siv ntawm cov kua ntim HEPA lub thawv tom kawg ntawm chav huv.
