PES membrane filter layer combination of efficient pre-filtering and filtering of the advantages of the terminal is a stable reliability, precision filter. It folded filter material is PES PES membrane, is the improvement of R & D AMC PES membrane for a variety of filtering applications. 
 PES membrane filter layer has a longer effective life and absolute filtering precision of the terminal can be used to filter, the filter can also be used as high-grade pre-filter to protect the more sophisticated end-filter to improve filtration efficiency, extend the terminal filter life. In the production process, each layer PES membrane filters are efficient in the same process conditions to be cleaned with a special solvent to protect the cleanliness. 
 Each layer PES membrane filters are effective for 100% integrity tested to ensure excellent quality. The U.S. and is the only certification authority of the filter.
