Filtration and separation is extremely important to the chemical and pharmaceutical industries, and many industrial processes require the coordination of different types of filtration equipment.

As the value of a customer's product increases so does the expectation placed upon the performance of the filter media.
Whether ready-made filter belts for horizontal vacuum filters, filter bags for centrifuges, cloths for chamber presses, covers for leaf filters, segments for rotary disc filters or replacement cloth covers with various profiles for rotary drum filters, a high degree of process safety and a long service life is required. Sefar's application specialists can make on-site suggestions as to the optimum filter medium.
With Sefar's wide range of fabrics, it offers solutions for almost every industrial environment paying attention to chemical, thermal and mechanical considerations.
Synthetic fabrics can be found in numerous filter applications in the chemical and pharmaceutical industry, including small-batch processing of high-valued products. This is because they and their associated filtration equipment can be used in many different processes and can meet all the necessary requirements such as good filter efficiency and performance, be easy to clean and maintain, have a long service life and be capable of hygienic design and able to fully conform to FDA requirements. Synthetic fabrics also have many advantages over other filter media including:
* Polymers like polypropylene have a large range of chemical and physical resistance.
* These advantages are even greater with new high-performance materials like PEEK (polyether-ether-ketone). PEEK also allows higher operating temperatures (up to 180°C).
* Unlike wire cloth, synthetic fabrics are not subject to metal-fatigue breaks.
* For similar efficiency and performance, costs are often less than when using other media.
* Due to the flexibility of synthetic monofilament yarns, cleaning is easier and can be even further improved by special finishing (calendaring) that provides an even smoother surface.
