This felt is a filtration material made by staple fiberglass being needle-punched to form a micro-porous felt with high porosity and low resistance, higher dust collecting efficiency. Its filtration speed is one times faster than ordinary filtration fabrics, thus decreases the costs of dust extractor. It is used for high temperature exhaust filtration in chemical, carbon black, cement, metallurgical industry, coal-fired boiler and power generation industry, suitable to bag filters with impulse or high velocity reversed air clean-down technology.

Both E-Glass and highsilica are available
