Teflon coated fiberglass

Fabric Filters. Fabric filters collect solid particles by passing gas through cloth bags that most particles cannot penetrate. As the layer of collected material builds on the fabric, the pressure differential required for continued gas flow increases consequently, the accumulated dust must be removed at frequent intervals. Fabric used to form the filter elements can range from nylon to wool to Teflon-coated fiberglass, shaped into cylindrical bags or envelopes with a roughly elliptical cross section. 

The typical method implemented is the installation of fabric filters. Teflon coated fiberglass or Nomex (nylon), in a gas cleaning equipment, commonly referred to as a baghouse. These devices are located downstream with respect to the cyclone and generally the gas is cooled before being treated.

If the exposure to corrosion is expected to be severe, materials with good corrosion resistance, such as PVC or fiberglass reinforced polyester materials, should be selected for the fans. If, for reasons of economy, ordinary steel fans are used, they should be coated with Teflon, or if the corrosion problem is somewhat less severe, PVC or polypropylene will serve.
