Filtration Solutions for Horizontal Vacuum Belt Filters

Sefar is the global leading manufacturer of woven filter cloths for Horizontal Vacuum Belt Filters.

Sefar invented the high-performance SEFAR TETEX® Double Layer Weave technology (DLW).

The filter media‘s unique construction combines two different fabric layers mechanically through weaving.

In comparison to a single layer fabric, belts made from SEFAR TETEX® DLW deliver outstanding filtration results: high vertical and lateral liquid flow properties, excellent resistance against creasing and mechanical stress, reduction of the cake moisture and solid content in the filtrate. Best filtration results in service life performance by combining the functions of a fine filtration layer and a support drainage layer.

Sefar also offers standard filter media types like SEFAR TETEX® MONO and SEFAR TETEX® MULTI fabrics, depending on the specific application.
