Sefar Filter Solutions for Filter Press Equipment

Sefar is a leader in the design, production and sales of chamber and membrane cloths for filter press machines, also called horizontal, mix pack or vertical plate pressure filters.

With 26 subsidiaries all over the world, Sefar has always focused on providing personal technical support and assistance to each customer and addressing the particular needs of their application.

Experience

Thanks to its strong experience in many applications, Sefar has developed a wide range of products to ensure:

Chemical, mechanical and abrasive resistance

Dimensional stability

Food compliance: FDA, EU 10/2011, EC 1935/2004, EC 2023/2006

Resistance of the media against clogging, blinding or scaling, coupled with a high regeneration capacity*
(*capacity of the woven fabric to recover the original permeability after a washing)

High strength resistance against tearing

Knowledge

For years, Sefar has gained knowledge and skills through many studies done internally in our specialized and well-equipped laboratory to reproduce filtration and the customer’s process. This approach has laid the foundation for the creation of media for filter press cloths with consideration for customer’s needs.

Cake moisture (cake dryness, moisture content)

Cake thickness

Filtration efficiency (filtrate clarity, solids in filtrate, particle retention, solids in suspension)

Cake release (cake discharge)

Cake washing efficiency

Solutions

Sefar proposes solutions to cope with all customer plate design, with ready-made and adapted cloths (single, double or overhang), which match perfectly to the plates and with options such as:

Metallic or US Eyelets, US eyelets are food grade and resistant to chemical degradation and corrosion.

Different types of barrels and rubbernecks, from the classic multifilament fabric to different waterproof options, able to resist all chemical or abrasion environments.

Edge sealing done through coating or reinforcement to avoid leakage, with a range of food grade certified coatings.

Support or backing cloth to increase drainage and lifetime of the filter cloth.


Fabrication solutions

Sefar's filter cloths are adapted to the different needs of the customers, like plate dimension, cake weight, particle retention or productivity. As a result, Sefar has developed a wide range of standard and specific designs, making up options for fixations, barrel and rubber neck, or sealing.

Filter media technology

A complete range of fabrics, including monofilament (SEFAR TETEX MONO), multifilament (SEFAR TETEX MULTI), mixed mono-multifilament, mixed multifilament-staple fibres, and other innovative products, are especially dedicated to filter press machines. Our range is able to cover all chemical requirements, with polymers such as Polypropylene (PP), Polyamide (PA, Nylon, Rilsan, PA6-6, PA 6, PA 6-10, PA11, PA12), Polyester (PET) or PBT, and particle retention with optimum flow rate, moisture content, and cake washing properties.

 

For this line, all the media are:

calendered to provide the smooth surface needed for a good cake release

properly thermo-fixed to ensure the dimensional stability

During this stage, the air permeability is monitored continuously to warrant uniformity and reliability and the pore size distribution of our line.
