In the world of industrial filtration, temperature is often the deciding factor between a successful process and a costly failure. Standard filter bags made from polypropylene or polyester are workhorses for general applications, but they encounter their physical limits when temperatures rise above 300°F (150°C). For operations dealing with extreme heat, Eaton Nomex (Meta-Aramid) High Temperature Filter Bags provide the necessary durability and thermal stability ensuring your process runs smoothly without downtime.
What Makes Nomex (Meta-Aramid) Different?
Nomex, technically known as Meta-Aramid, is a high-performance fiber engineered to possess excellent thermal resistance. Unlike standard plastics that soften or melt under heat, Aramid fibers maintain their structural integrity in temperatures up to 400°F (204°C). This makes them the premier choice for demanding filtration tasks where other media would fail.
Eaton leverages this material to create filter bags that offer not only heat resistance but also exceptional durability against abrasion and flex fatigue. These bags are typically constructed using needlefelt, a depth filtration media that effectively captures solid particles within the matrix of the fabric, ensuring high dirt-holding capacity.
Technical Specifications
Understanding the capabilities of your filter media is crucial for system safety and efficiency. Below is the technical profile for Eaton’s High Temperature Meta-Aramid bags.
| Specification | Detail |

Key Features
- Thermal Stability: Resists continuous operating temperatures that would degrade polyester or polypropylene instanly.
- Broad Chemical Compatibility: Excellent resistance to organic solvents, making it ideal for chemical processing.
- High Dirt Holding Capacity: The needlefelt structure allows for deep particle retention, extending the time between bag changes.
- Sealing Options: Available with Eaton’s advanced sealing rings (such as the SENTINEL® seal) to prevent fluid bypass.
Ideal Applications for High-Temperature Bags
The specialized nature of Eaton Nomex bags makes them suitable for industries where process fluids are kept viscous by heat or where the reaction itself is exothermic.
Chemical Processing
Filtration of resins, hot oils, and solvents often occurs at elevated temperatures. Nomex bags ensure that no synthetic fibers melt into the product, preserving purity [eaton.com].
Oil & Gas / Asphalt
Asphalt processing and hot oil filtration require media that stays robust under thermal stress. Aramid fibers provide the necessary resilience for these harsh environments.
Metal Working & Parts Cleaning
In parts cleaning, fluids are often heated to improve degreasing efficiency. High-efficiency bags remove fine particulate matter from these heated baths, ensuring parts meet stringent cleanliness standards before coating or assembly [purecowater.com].
