Filter Media

AFF’s technical sales staff gets to choose from dozens of fabrics when they’re designing your filters, connectors or other custom products.  In addition to common woven and no-woven textiles, we stock vinyl/rubber-coated fabrics and synthetic/stainless steel screening materials.  We also work with an extensive range of special order fabrics for applications needing high temperature, chemical resistance, extra strength or air permeability.  Many unique fabrics are, or can be treated to shed sticky dust, bleed static electricity and resist burning.
