A Glass Fiber Filter Bag (also known as a fiberglass filter bag) is a high-temperature-resistant filtration bag made from glass fiber fabric, used in industrial dust collection systems—especially where hot and potentially corrosive gases are present. It is commonly used in boilers, spray dryers, cement kilns, foundries, and waste incineration plants.

🔹 Glass Fiber Filter Bag – Overview ✅ Material:
Made from continuous filament glass fibers woven into fabric or formed into felt.
Can be treated with coatings like:
PTFE (Teflon) – improves chemical resistance and prevents dust build-up.
Silicone, graphite, or acid-resistant finishes – enhance durability and reduce brittleness.
