Dust Collection Filter Bags for Steel & Metal Processing | EAF & Smelting | Farrleey

Electric arc furnaces and smelting operations generate some of the most challenging filtration conditions: ultra-fine metallic oxide fumes, abrasive particulate, and intense, fluctuating heat. Standard filter bags quickly fail, leading to frequent downtime, high replacement costs, and emission control issues. Farrleey's high-temperature filter bags are specifically formulated to deliver reliable performance and extended service life in these punishing environments.

Critical Performance for Your Melt Shop & Smelter:

• Superior Thermal Resilience for EAF Operations

  • Confidently handles the high-temperature, high-huminity gases from electric arc furnaces. Rated for continuous operation at 250°C and built to survive short-term thermal spikes up to 280°C, protecting your system from process upsets.

• Advanced Protection Against Metal Fumes

  • The robust PTFE and Polyimide (PI) blend offers exceptional resistance to chemical attack from acidic metal oxides and other corrosive elements found in furnace off-gases, preventing premature media degradation.

• Essential Safety in Hazardous Environments

  • An integrated permanent anti-static PTFE scrim ensures static electricity is safely dissipated, significantly reducing the risk of ignition in areas with combustible dust—a critical safety feature for handling fine metal powders.

• Unmatched Durability Against Abrasion

  • Exceptional tensile strength (> 800 N/5cm MD, >1000 N/5cm CD) provides outstanding resistance to the abrasive nature of metallic dusts and the stress of aggressive pulse-jet cleaning cycles, maximizing bag life and minimizing maintenance.
