Fiberglass fabricated filter bags are used for collecting of fine particles of dust (generated during various industrial procedures). Available in different thickness and length based choices, these dust filtering bags have PTFE membrane based design. There are several advantages of fiberglass filter bags. These bags are well known for their low moisture and oil absorption level, stable chemical attribute (that remains unaffected even after exposure to strong acid and alkali) and good dimensional stability. More than 99% dust filtration efficiency, accessibility in different textures ( as for instance, plain/slopping/broken loop etc) and high temperature proof design are some of the remarkable aspects of provided fiberglass bags.
