The right filter media for separation, purification, filtration, screening and sieving of a suspension or powder in the chemical process industry

In the chemical industry, efficient and economic liquid-solid and powder separation, drying and product screening for quality control is a vital processing stage and the key to success. Sefar offers a wide range of fabric filters and filter media designed for use on various filter equipment including:

Rotary drum filter

Pressure leaf filter

Vacuum belt filter

Disc filter

Candle filter

Filter press

Nutsche filter

Vacuum dryer

Bag house



Sefar, a specialist in technical textiles, supports research and development departments, process engineers, and maintenance and production managers in achieving their goals concerning process optimization, process development and sustainability. Ecological and economically sustainable innovation of products and product filters is essential. Continuous improvement and further development of resource-saving, efficient and effective processes is a core task of the chemical industry. Mechanical, chemical, physical, biotechnological or process engineering projects confront chemical companies every day. Building up application knowledge combined with experimentation in the laboratory and implementing it into production, all require a competent partner. Sefar supports those experiments in the laboratory or production where mechanical separation takes place. Helping to optimize process equipment and implement the result in production environments in order to achieve optimal separation of the filtrate from the solid, is crucial for success.

Process targets

Reduction of the residual moisture of the filter cake and improved cake release in automated filter presses

Improvement of particle retention and optimization of filter efficiency

Increase in production capacity

Reduced particle strike-through and increased filtrate clarity

Process improvement and increased efficiency in process engineering challenges

Reduction of the resistance to the filter medium of fabric filters

Improvement of the separation task and ensuring the quality of the screening

Fulfillment of all food conformity declarations under the heading of 'compliance', 'food conformity (FDA)' and any other associated certification

Optimization of the operating costs, total cost of ownership or sustainability projects

Wide selection of filter media

A wide range of monofilament and multifilament filter fabrics as well as mesh or screen filters and sifters guarantee the most appropriate filter fabric to achieve optimum yield. No matter if micro, vacuum, pressure or centrifugal filtration – whether it be the mechanical dehumidification of the filter cake, the increase in throughput or the improvement of particle retention, Sefar experts assist in the selection of the correct mesh size or pore opening of the filter depending on the particle size and requirements of the process. Sefar’s advice about the optimization of flow rates and pressure differences is complemented by the equally important advice about the compatibility of the filter with the corresponding filter apparatus. The choice of which of the various filter materials such as polypropylene (PP), polyester (PET), Teflon (PTFE), nylon (PA6.6), polyamide (PA such as Rilsan), PBT, PEEK, PPS, E-CTFE, ETFE and PVDF are used help to achieve the many chemical requirements of the filter elements in the acidic or alkaline range as well as to have the required solvent resistance. Sefar takes into account requirements for hydrolysis-critical, temperature-intensive processes and application areas for screening, separation, drying or filtration as well as special requirements for Food Conformity (FDA) and EU guidelines for food contact. Process optimization and improvement are not only possible in solid-liquid separation, but also in drying and screening technology.

Application know-how and customer support

In addition to the expertise in the field of filter fabrics, Sefar has broad application knowhow in the construction of filter elements. Beside roll goods, fabric cuts (e.g. laser-cut) and accessories, Sefar offers a wide range of ready-made filters: filter tube, filter bag, pocket filter, filter press cloth (single, overhang, double), belt filter, tubular fabric, leaf filter, disc filter, fluid-bed dryer (FBD) filter, dryer belts, drum filter sleeves, paint screening filter, pressure plate filter, press filter cloth, cartridge filter, centrifuge bag, centrifuge liner, nutsche filter, screens and sifters (centrifugal sifters or plansifters). Constant optimization of our product offering helps to solve customer's tasks quickly, efficiently and effectively. Simple installation and maintenance are the basic priorities kept in mind in the development stage and thus ensures constant and consistent high quality together with lasting success.
