Nomex Dust Filter Bag High Temperature Wear Resistant Needle Felt Pulse Dust Collector Custom Bag

Our Nomex filter bags are high-performance industrial filtration products designed to meet the most demanding dust collection and gas filtration needs in harsh industrial environments. Made from 100% premium meta-aramid Nomex fibers developed by DuPont, our Nomex filter bags stand out for their exceptional thermal stability, flame resistance, mechanical durability, and chemical compatibility—making them the first choice for industries that require reliable filtration under extreme conditions.

Unlike ordinary filter bags that easily degrade under high temperatures, corrosive gases, or abrasive dust, our Nomex filter bags deliver long-lasting performance, reduce maintenance costs, and ensure compliance with stringent environmental emission standards. Whether you operate in asphalt plants, cement factories, steel smelters, or waste incineration facilities, our Nomex filter bags provide consistent, efficient filtration that you can trust.Nomex filter bags are engineered to address the critical challenges of industrial filtration, where high temperatures, abrasive particles, and chemical exposure often lead to frequent filter bag failures and unplanned downtime. Our Nomex filter bags are crafted with advanced needle-punching technology, which creates a dense, uniform felt structure that effectively captures fine dust particles down to 1 micron while maintaining excellent air permeability. This unique structure not only ensures high filtration efficiency (up to 99.99%) but also minimizes pressure drop, reducing energy consumption of your dust collection system. What sets our Nomex filter bags apart from competitors is our strict quality control throughout the production process—from selecting high-grade Nomex fibers to precision sewing and heat-setting treatments, every step is designed to enhance the durability and performance of our Nomex filter bags.

One of the most significant advantages of our Nomex filter bags is their outstanding high-temperature resistance. Our Nomex filter bags can withstand continuous operating temperatures up to 204°C (399°F) and short-term thermal spikes up to 260°C (500°F), making them ideal for applications with high-temperature flue gases, such as asphalt mixing plants and steel melting furnaces. Unlike polyester or PPS filter bags that melt or degrade at temperatures above 130°C and 160°C respectively, our Nomex filter bags maintain their structural integrity even under prolonged exposure to high heat, significantly extending their service life. Additionally, our Nomex filter bags have inherent flame resistance with a limiting oxygen index (LOI) of 29–32%, meaning they are self-extinguishing in air and can prevent bag fires caused by hot sparks or embers—a critical safety feature for industries with high fire risks.

Another key benefit of our Nomex filter bags is their exceptional mechanical strength and abrasion resistance. The meta-aramid fibers used in our Nomex filter bags have high tensile strength (≥ 900 N in warp direction and ≥ 1200 N in weft direction), making them resistant to tearing, bursting, and wear from abrasive dust particles such as sand, stone fines, and clinker. This abrasion resistance ensures that our Nomex filter bags can withstand the rigors of pulse-jet cleaning and continuous dust collection, reducing the frequency of filter bag replacements. Compared to ordinary filter bags that need to be replaced every 6–18 months, our Nomex filter bags have a service life of 24–48 months, depending on the application, which significantly lowers maintenance costs and unplanned downtime for your facility.

Our Nomex filter bags also offer excellent chemical resistance, making them suitable for use in environments with corrosive gases and dust. They have good resistance to weak acids, alkalis, and most hydrocarbons, and can maintain their performance in environments with fluorides or sulfur oxides—common in cement plants and chemical facilities. Unlike PPS filter bags that are sensitive to alkaline dust, our Nomex filter bags remain stable even in pH ranges from 1 to 14, ensuring reliable filtration in complex chemical environments. This chemical stability, combined with their high-temperature resistance, makes our Nomex filter bags versatile and suitable for a wide range of industrial applications.

We understand that every industrial facility has unique filtration needs, which is why our Nomex filter bags are fully customizable. We offer a range of specifications for our Nomex filter bags, including different weights, thicknesses, micron ratings, and surface treatments (such as PTFE coating) to meet your specific application requirements. Our Nomex filter bags are available in weights from 350 g/m² to 750 g/m², thicknesses from 1.4 mm to 2.4 mm, and micron ratings from 0.5 to 200 microns, ensuring that you can find the perfect Nomex filter bags for your dust collection system. Additionally, we offer various top and bottom configurations, including snap band top, ring top, sewn flat bottom, and disc bottom, to ensure easy installation and compatibility with your existing baghouse.
Below are the detailed technical parameters of our Nomex filter bags, which demonstrate their superior performance and quality. All our Nomex filter bags are tested and certified to meet international industrial standards, ensuring that they deliver consistent and reliable filtration performance.

Our Nomex filter bags are widely used in various industrial sectors, including asphalt plants, cement production, steel smelting, non-ferrous metal production, waste incineration, power generation, and chemical processing. In asphalt plants, our Nomex filter bags effectively handle flue gas temperatures of 180–220°C and abrasive dust, ensuring compliance with emission standards below 20 mg/m³. In cement plants, they withstand the corrosive effects of alkaline dust and high temperatures in kiln and cooler baghouses. In steel mills, our Nomex filter bags capture fine dust particles from steel furnaces, improving air quality and protecting equipment.Choosing our Nomex filter bags means choosing a reliable, cost-effective filtration solution that delivers long-term value.
