Filter Media

AFF 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, synthetic/stainless steel screening materials. We also work with an extensive range of special order fabrics for application 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 or resist burning.
