As a manufacturer with over 20 years of experience in wire mesh and filtration products, Anping County Boli Hardware Wiremesh Products Factory (est. 1998) is proud to introduce our High Temperature Resistant Dust Filter Cartridge, specifically engineered for the demanding conditions of steel mills. This cartridge is designed to withstand continuous operation at 260°C, ensuring reliable performance in extreme heat environments. Our factory, located in Hengshui, Hebei, China, has exported millions of dollars worth of filtration solutions to over 20 countries, and this product reflects our commitment to quality and durability.
The filter cartridge is constructed with a premium fiberglass base combined with a PTFE membrane, offering excellent thermal stability and chemical resistance. It is specifically designed to capture fine dust particles generated during steel production, such as iron oxide, silica, and coke dust. With a filtration efficiency that can reach up to 99.9% (when using optional high-grade media), this cartridge helps steel mills meet stringent emission standards while maintaining high airflow rates.
Key Features & Benefits:
- Continuous 260°C operation – The fiberglass substrate and PTFE membrane can sustain prolonged exposure to high temperatures without degradation, unlike standard polyester filters.
- Low pressure drop – The pleated design maximizes surface area, reducing resistance and saving energy on fan systems.
- Easy cleaning – The smooth PTFE surface allows for efficient pulse-jet cleaning, extending cartridge life and reducing maintenance frequency.
- Customizable dimensions – Available in various lengths (600mm, 900mm, 1200mm) and diameters (130mm, 150mm, 200mm) to fit most dust collector systems. Custom sizes are also available upon request.
- Corrosion and moisture resistance – The PTFE layer protects against acidic gases and moisture often present in steel mill exhaust.
- High dust holding capacity – The deep pleat structure allows for significant dust accumulation before requiring cleaning, improving operational efficiency.

Frequently Asked Questions (FAQ)
-
Q: Can this filter cartridge be used for continuous temperatures above 260°C?
A: The cartridge is designed for continuous operation up to 260°C. Short-term surges up to 280°C are acceptable, but prolonged exposure above 260°C may reduce service life. For higher temperature applications, we can discuss alternative media options. -
Q: What is the typical lifespan of this cartridge in a steel mill environment?
A: Lifespan depends on operating conditions, cleaning frequency, and dust characteristics. In typical steel mill applications, with proper pulse-jet cleaning, the cartridge can last 12–24 months. We recommend periodic inspection and pressure drop monitoring. -
Q: Can I get a custom size or different end cap design?
A: Yes, we offer customization. Please provide your existing filter dimensions, or we can design based on your housing. Minimum order quantities may apply for custom sizes. -
Q: Is this cartridge washable? Can I use water or compressed air?
A: We recommend dry cleaning methods such as pulse-jet or reverse air. Washing with water is not recommended as it may damage the media. If wet cleaning is unavoidable, consult our technical team. -
Q: What certifications do you have for this product?
A: As a manufacturer, we adhere to internal quality control standards. While specific third-party certifications are not listed, we can provide material test reports and performance data. For specific certification requirements, please contact us to discuss feasibility. -
Q: Do you offer samples before bulk order?
A: Yes, we provide samples for evaluation. Sample cost and shipping are negotiable. Once approved, we can proceed with mass production. -
Q: What is the difference between your PTFE membrane cartridge and a standard polyester cartridge?
A: Standard polyester cartridges are limited to about 135°C continuous temperature. Our fiberglass + PTFE membrane cartridge can withstand 260°C. Additionally, the PTFE membrane provides superior release properties for sticky dust, leading to easier cleaning and lower pressure drop. -
Q: How do I choose the correct length and diameter for my dust collector?
A: Measure the existing filter cartridge or the housing dimensions. Common sizes are 130mm or 150mm outer diameter, with lengths from 600mm to 1200mm. If you’re unsure, send us a photo or drawing, and we will help identify the correct size.
