Betamesh is a further development of the plain weft. It has significantly more pores than normal plain braid, and the pores on the surface are smaller than the inner pores. The fabric has a comparatively high flow rate and dirt holding capacity and is characterized by excellent backwashing properties. These fabrics are generally used for oil and fuel systems where higher levels of contamination are present and to protect control and injection nozzles as well as plain bearings. Betamesh R is a variant for simple filtration tasks, which is particularly suitable for higher mechanical loads due to the Robusta weave.
