Depending upon the filtration application, different requirements have to be fulfilled. A number of standards exist for the development of filters as well as air and liquid filter media for different applications. Sometimes it is necessary to combine different filtration media to best fit the application’s requirements. As well as describing the standards, the structural design of the filters and their manufacturing technologies are discussed. Some technological priorities that have arisen due to the introduction of stringent environmental regulations are discussed and future trends are documented.
We primarily stock Polyester with plain and singe finishes, and Polypropylene with plain and glazed finishes. Ask about any of our value-added converting services like slitting & die cutting.
