Clean roomFFU filter membrane‘s filtration grade is usually classified according to its ability to remove particulate matter. The following are some common clean roomFFU filter membranefiltration grades:
1. HEPA filter ( Air filter): HEPA filter membrane is one of the most common and widely used clean room filters. It has high filtration efficiency and can remove particles with a diameter of 0.3 microns. The filtration efficiency of HEPA filters can reach more than 99.97%.
2. ULPA filter (ultra-low permeability air filter): ULPA filter membrane is a higher-level filter than HEPA filter. High filtration efficiency. It can remove particles with a diameter of 0.1 microns and has a filtration efficiency of over 99.9999%.
These filtration ratings are evaluated according to standard test methods such that the filter provides high filtration effectiveness within a specified particle size range. Choosing the appropriate filtration level depends on the air quality requirements in your specific cleanroom environment.
It should be noted that the filtration grade only describes the filter’s ability to filter particulate matter, and does not include the filtration of gases, chemicals or other pollutants. In cleanroom designs, it may be necessary to incorporate other types of filters or control devices to meet specific contaminant requirements. Therefore, when selecting FFU filter membrane and designing a clean room, the needs of the specific environment should be taken into consideration.
