A boiler filter bag (also called a baghouse filter bag or dust collector bag) is a type of industrial filtration device used in boiler systems to capture and remove fine particles, ash, and dust from flue gas emissions. These bags are a critical component in maintaining air quality, meeting environmental regulations, and protecting downstream equipment.

Boiler Filter Bag – Key Features:
Material: Typically made from heat-resistant synthetic fabrics such as PPS (polyphenylene sulfide), Nomex (aramid), PTFE (Teflon), P84, or fiberglass, depending on the operating temperature and chemical exposure.
Temperature Resistance: Designed to withstand high flue gas temperatures (up to 260°C or more), depending on the fabric used.
Filtration Efficiency: Can filter particles as small as a few microns, achieving 99% or greater dust collection efficiency.
