Nomex filter bags are made with meta-aramid fiber technology to capture fine dust (including PM2.5) while resisting the chemical attack of acidic flue gases (e.g. SO₃, HCl). Unlike common filtration media that degrade under thermal stress, they provide unrivaled durability in environments with temperatures exceeding 240°C. Ideal for demanding applications such as power plants, asphalt plants, cement kilns, steel furnaces and metallurgical processes.
Precision filtration
99.99% capture of 10 micron particles; 99.5% capture of 1 micron particles.
01
High Temperature Resistance
Maintains full functionality at 240°C (428°F), outperforming polyester and fiberglass alternatives that fail at temperatures above 150°C.
02
Chemical Warfare Defense
Acid and Alkali Resistance: Handles environments with a pH of 3-11, making it ideal for waste incinerators exposed to HCl vapors or metallurgical processes rich in alkaline dust.
03
Abrasion resistance
Designed for highly abrasive particles such as raw cement, fly ash with SiO₂ content > 45%.

Fiber Blending & Carding: Uniform dispersion of Nomex fibers for consistent basis weight and thickness.
Needle Punching & Heat-Setting: Mechanical bonding and thermal stabilization ensure dimensional stability under cyclic temperatures.
Surface Singeing: Controlled flame or thermal treatment reduces surface fuzz and fiber migration.
PTFE Impregnation (Optional): Enhances dust release and chemical resistance; applied via specialized padding and curing processes.
Quality Inspection: In-house testing for air permeability, tensile strength, and filtration efficiency under simulated operating conditions.
European Power Plant Retrofit
Replaced polyester bags with Nomex PTFE-laminated bags in a 300MW coal plant.
Result: 40% longer service life, emissions reduced to <10mg/Nm³.
