Fiberglass yarns are fragile and require a finish that allows the yarns to move under use without abrading each other. Summit offers its fiberglass filter bags with a choice of three finishes:

  • 10% (Min) PTFE
    This is a premium finish that provides outstanding lubrication for fiber movement. The PTFE finish provides a slick surface for dust release and protection against attack by water borne acids and chemicals. It is the most asked for finish for pulse jet use.

  • Acid Resistant
    This finish provides resistance to water borne acids using lower cost ingredients. It is used in pulse jet as well as reverse air baghouses.

  • Silicone/Graphite/Teflon (SGT)
    This low cost finish is mostly used in reverse air baghouses. It is a light duty finish used when fabric movement is minimal.
