PPS High Temperature Needle Felt Filter Cartridge

This filter cartridge is fabricated with polyphenylene sulfide (PPS) fiber needle felt, an internal metal support cage and metal end caps. Its dense interlaced fiber structure performs depth filtration for coarse and ultra-fine dust. PPS provides strong resistance to heat, acids and hydrolysis for medium-high-temperature, humid and sulfur-containing flue gas.
