Data Sheet: Polyester Felt, Anti-Static GORE® Filter Bag 475 g/m2 (14 oz/yd2)

English

A 135°C (275°F) maximum service temperature, anti-static polyester felt filter bag for use in pulse-jet style dust collectors where static dissipation is required.


Features and Benefits

  • Patented GORE™ High Durability membrane technology provides an excellent combination of filtration efficiency, airflow, and durability
  • Polyester fibers provide good all-around chemical resistance, especially in applications operated below 79°C (175°F) 
  • Special multifilament scrim design provides excellent dimensional stability and resistance to mechanical damage over the life of the filter
  • Carbon-filled poly-acrylonitrile co-polymer fibers provide static dissipation (passes NFPA-99 Laminate Static Decay Test)

Applications

  • Chemicals processing: dryer baghouses, bin vents, and nuisance dust collectors in the pigment, plastic, and catalyst industries
  • Minerals processing: coal mill collectors
  • Metals processing: process-venting and material-handling dust collectors for pulverized coal
  • Power generation and Incineration: coal-handling collectors and coal-milling baghouses
