Nomex Needle-Punched Felt
Nomex Needle-Punched Felt is a meta-aramid (Nomex®) fiber filter media engineered for high-temperature, abrasive, and chemically moderate dust-gas environments. It provides excellent thermal stability, strong abrasion resistance, low shrinkage, and reliable long-term performance in demanding industrial filtration systems.
Nomex felt is a cost-effective choice for plants operating in the 180–200 °C continuous temperature range with dusty, abrasive, or mildly corrosive gas streams.
Nomex felt delivers stable, long-term performance in high-temperature, high-dust systems:
Nomex withstands continuous 180–200 °C and peak 220–240 °C without hardening, brittleness, or significant thermal shrinkage, ensuring stable long-term performance.
Aramid fibers provide excellent resistance to abrasive dust, high-velocity particles, flex fatigue, and mechanical wear, extending bag life in heavy-dust systems.
Resistant to mild acids, alkalis, and organic compounds, making Nomex suitable for asphalt mixing plants, cement mills, dryers, chemical processes, and biomass/coal boilers.
Nomex maintains stable air permeability, low shrinkage under heat, and consistent filtration efficiency even under continuous pulse-jet cleaning cycles.
Ideal for systems where PTFE or P84 are unnecessary; offers an excellent balance of temperature resistance, durability, and budget efficiency.
Available as roll felt or custom-fabricated filter bags with optional PTFE membrane, surface finishing, and reinforced designs tailored to specific dust-collector requirements.

Nomex Needle-Punched Felt is engineered for high-temperature, abrasive, and chemically moderate industrial dust-gas environments. Its meta-aramid fiber construction provides stable performance in the 180–200 °C continuous range (peaks 220–240 °C), low shrinkage, strong abrasion resistance, and reliable filtration efficiency under frequent pulse-jet cleaning.
Preheaters, coolers, and mineral-processing lines generate hot, abrasive dust with moderate SO₂/NOₓ levels. Nomex felt maintains dimensional stability and abrasion resistance in the 180–200 °C range, helping extend bag life and keep emissions under control.
Asphalt drum mixers, sand/mineral dryers, and coal/biomass boilers expose filters to hot, dust-laden gas and frequent temperature fluctuations. Nomex felt handles these thermal cycles well, offering good dust release and stable pressure drop under continuous pulse-jet cleaning.
Foundries, metalworking shops, dryers, and process exhaust systems generate abrasive, high-dust gas streams. Nomex felt’s high mechanical strength and flex-fatigue resistance provide dependable service life and consistent filtration where gas chemistry is moderate but mechanical wear is severe.
