ABSTRACT:
A novel filter element is constructed from expanded polytetrafluoroethylene (ePTFE) membrane possessing high strength which is sufficient to withstand filtration processing, as well as permitting the use of low energy to flex and clean the filter element. Further, the novel filter element of the present invention is non-linting and non-contaminating due to the ePTFE membrane structure of the filter, thereby providing excellent filtration performance for a variety of industries requiring high efficiency filtration.
