The three commonly used dust removal bags are polyester needle felt, glass fiber filter cloth, and polytetrafluoroethylene (PTFE) filter cloth.
Polyester needle punched felt bag: mainly used in boiler dust collectors and industrial dust collectors, its advantages are high cost-effectiveness, low resistance, long service life, easy cleaning, and suitable for occasions with large dust particles.
Glass fiber filter bag: mainly used in high-temperature and high-pressure dust removal occasions in industries such as electric furnaces, steel, cement, etc. Its advantages are high temperature resistance, corrosion resistance, high filtration efficiency, and long service life.
Polytetrafluoroethylene (PTFE) filter bag: mainly used in high concentration, high temperature, corrosive and toxic gas environments, such as oil refining, chemical and other industries. Its advantages are low resistance, corrosion resistance, high temperature resistance, adhesion resistance, high filtration accuracy, and good ash cleaning performance. But its cost is relatively high.
