Anping County Boli Hardware Wiremesh Products Factory (established in 1998) is a professional manufacturer specializing in wire mesh and filtration products. With an annual export value of US$5–10 million and a global presence across North America, South America, Europe, Asia, Africa, and Oceania, we bring decades of expertise to the production of high-performance filter cartridges. Our Customized 304 Stainless Steel Dust Filter Cartridge with 0.5-Micron Filtration for 220°C Operation is designed to meet the most demanding industrial dust collection requirements, combining robust construction with precision filtration for reliable long-term performance.
This cartridge is engineered from marine-grade 304 stainless steel, offering excellent corrosion resistance and mechanical strength even under high-temperature conditions. The 0.5-micron filtration rating ensures capture of sub-micron particles, making it ideal for applications where air quality and process efficiency are critical. Whether you need a standard size or a fully customized dimension, our flexible manufacturing capabilities allow you to specify outer diameter, inner diameter, length, and sealing type to seamlessly integrate with existing dust collector systems.
Key Features & Benefits
- 304 Stainless Steel Construction: Resists rust, corrosion, and thermal degradation, ensuring a long service life in harsh environments.
- 0.5-Micron Filtration Efficiency: Captures fine dust, powders, and even some bacterial particles, improving workplace air quality and protecting downstream equipment.
- 220°C Continuous Operation: Suitable for high-temperature exhaust streams, drying processes, and other hot gas filtration applications.
- Full Customization: Choose from a wide range of diameters (50–500 mm), lengths (100–2000 mm), and end cap configurations (flange, threaded, gasket seal).
- Pleated Design for High Flow: Maximizes filtration surface area while maintaining low pressure drop, reducing energy consumption.
- Easy Cleaning & Maintenance: Can be backwashed or ultrasonically cleaned for reuse, lowering operational costs.
- Reinforced Structure: Inner and outer support meshes prevent collapse under high differential pressure.

Frequently Asked Questions
Q1: Can the filter cartridge be customized to fit my existing dust collector?
A: Yes, we offer full customization on outer diameter, inner diameter, length, and end cap style. Please provide your current filter dimensions or a drawing, and we will manufacture accordingly.
Q2: What is the maximum temperature this cartridge can withstand continuously?
A: It is rated for continuous operation at 220°C. For short-term peaks up to 250°C, please consult our technical team for material compatibility.
Q3: How often does the filter need to be replaced?
A: The service life depends on the dust load, cleaning frequency, and operating conditions. Because it is made of stainless steel, it can be cleaned repeatedly (e.g., backwashing, ultrasonic cleaning) and typically lasts 1–3 years in normal industrial use.
Q4: Is the filtration efficiency tested?
A: Yes, each batch is tested for filtration efficiency. We guarantee ≥99.9% capture for particles sized 0.5 micron and above. Test reports are available upon request.
Q5: What sealing options are available?
A: We offer flange (bolt-on), threaded, or gasket seal connections. The gasket material can be silicone, PTFE, or other high-temperature resistant materials.
Q6: Can this cartridge be used for wet or sticky dust?
A: The 304 stainless steel surface can be electropolished to reduce adhesion. However, for very sticky materials, we recommend a PTFE coating or a different pleat geometry. Our engineers can advise on the best solution.
Q7: Do you provide samples before bulk order?
A: Yes, free samples are available for evaluation. You only need to cover the shipping cost. Sample lead time is 7–15 business days.
Q8: What is the typical lead time for a customized order?
A: For standard custom sizes, production takes 15–25 working days. For highly specialized designs, please allow 20–30 working days. Urgent orders can be expedited upon request.
