A 260 °C (500 °F) maximum service temperature, expanded polytetrafluoroethylene felt filter bag for use in back washable liquid filter systems with chemically aggressive operating conditions.
Features & Benefits
- Patented GORE™ High Durability Membrane technology provides an excellent combination of filtration efficiency, liquid flow, and durability.
- Chemically inert providing the highest all-around chemical resistance and maximum bag life.
- Constructed using a woven ePTFE scrim that provides excellent dimensional stability, extended flex life, and resistance to mechanical damage over the life of the filter.
- Chloralkali Processing: Brine filtration for removal of Ca, Mg, Fe and Hg precipitates in the primary brine treatment area prior to electrolysis.
- Sodium Chlorate: Removal of iron compounds from chlorate solutions prior to crystallization.
- Sodium Hypochlorite: Filtration of high-strength bleach solutions for removal of fines that cause bleach decomposition.
