We offer customized Nomex filter bag solutions tailored to each customer’s unique operating conditions. Driven by continuous process innovation, we keep improving filter bag performance to deliver outstanding reliability even in harsh working environments.
Nomex filter bags sustain a continuous operating temperature of up to 200°C (392°F), with short-term peak temperatures reaching 250°C (482°F).
They feature satisfactory resistance to acids and alkalis, adapting well to working environments containing aggressive chemical media.
Nomex fiber delivers superior mechanical strength, granting the filter bags great durability and extended service life.
Thanks to the inherent abrasion resistance of Nomex fibers, the filter bags can endure severe wear during dust collection operations.

Technical Advantages of Nomex Filter Bag Production
The base fabric of aramid needle felt filter bags is produced from premium high-tenacity aramid filament fibers, which endow the filter bags with reliable mechanical strength. It undergoes pre-treatment and heat setting to achieve an aramid base fabric with stable dimensions and consistent performance.
The production of Nomex filter bags adopts a sequence of precisely controlled processes to satisfy the strict criteria of industrial filtration. Starting from Nomex fiber processing through cutting, stitching and final finishing, every procedure is engineered to deliver durable, high-performance filter bags that withstand high temperatures and aggressive chemical conditions.
Double-stitched seams with high-temperature resistant sewing thread for reliable sealing.
Multiple options are available, such as snap band, ring top and flange top, enabling quick installation and tight fit.
Built-in support rings or other reinforcing structures preserve the filter bag shape and maintain optimal air flow distribution.
Optional grounding wire is offered to eliminate static accumulation for applicable working conditions.
A wide range of optional special treatments: singeing, calendering, heat setting, anti-static finishing, water & oil repellent treatment, PTFE membrane lamination and PTFE impregnation.
For filtration of high-temperature and abrasive dust.
Suitable for electric arc furnaces and other high-temperature dust collection scenarios.
Ideal for fly ash capture and flue gas desulfurization systems.
Used for dust removal in hot mix asphalt manufacturing.
Applied in high-temperature environments containing corrosive chemical media.
For diverse industrial operating conditions including high-temperature flue gas, corrosive environments and high dust load, FilterEXP carries out systematic optimization covering fiber selection, fiber blending and needle punching processes. Paired with advanced finishing treatments such as singeing, calendering, heat setting, PTFE membrane lamination and water & oil repellent finishing, our filter bags achieve higher filtration efficiency, better dust cake release and longer service life.
We also provide flexible customization on dimensions, geometries and structures, including round filter bags, flat bags and special-shaped bags. This ensures perfect compatibility with different dust collector systems, lowering air flow resistance while boosting system stability and energy efficiency.
Aimed at a wide range of industrial conditions involving high-temperature flue gas, corrosive gaseous media and high dust loading, FilterEXP implements systematic optimization throughout fiber formulation, blending and needle-punching procedures. Integrated with premium post-finishing technologies including singeing, calendering, heat setting, PTFE membrane lamination and hydrophobic-oleophobic treatment, the finished filter bags provide upgraded filtration efficiency, excellent dust shedding property and extended operational lifespan.
Moreover, we support bespoke customization of dimensions, outlines and structural forms, such as cylindrical bags, flat bags and irregular special configurations. They are engineered to fit seamlessly with different dust extraction systems, minimizing differential pressure and enhancing the overall stability and energy efficiency of the dust collection unit.
