How much do you know about high-efficiency filtration membranes in clean rooms? Do you know what kind of material it is? Today we will take a closer look.
The collection efficiency of the medium-efficiency filter is intermediate between the extensive filter and the high-efficiency filter. In the clean room filtration system, it is generally installed in front of the high-efficiency filter, especially at the outdoor air inlet. It is absolutely necessary.
For example, when estimating filter life, 80% of the air supply volume comes from the circulating air in the clean room, and 20% comes from the outdoor air.
Although external air accounts for a relatively small proportion of the total air volume, the concentration of dust accounts for the overwhelming majority. It is mainly outdoor air that blocks the filter holes.
The porosity of the clean room high-efficiency filtration membrane filter material can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um, and has high and low temperature resistance Performance (-200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
It can ensure complete retention of bacteria and other impurities while having a large flux.
It has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
The clean room high-efficiency filtration membranes produced by the manufacturer use imported raw materials, have a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of ptfe membrane; using Production and testing instruments imported from the United States test the quality of PTFE film, and have passed international SGS testing and certification, as well as ISI testing and certification.
