With benefits including precisely tailored flow rates and accuracy – wire diameters and mesh apertures can be customized to perfectly match targeted contaminants – woven metallic filter fabrics continue to be essential for many demanding filtration operations. In addition, metal mesh filters – primarily made from stainless steel – can withstand a wide range of …

Illustration of chemical bonding technique.

The bonding of fibers and polymers in the filter media manufacturing process can be performed by mechanical, chemical or thermal processes. Chemical bonding in filtration is typically employed to provide added binding of raw materials and/or added functionality to the filter media (anti-microbial, hydrophobicity, hydrophilicity, etc.). Gravure printing is a process whereby the filter material …
