As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in industrial filtration solutions. Our Welding Fume Extraction Filter with 0.3 Micron HEPA and Polyester Flange-Clamp Design is engineered to capture hazardous welding fumes, protecting workers and equipment. With annual exports exceeding US$5 million and shipments to global markets including North America, Europe, and Asia, we deliver consistent quality backed by decades of experience.
This filter combines a high-efficiency HEPA media with a durable polyester substrate to trap submicron particles, including metal oxides, smoke, and fine dust. The flange-clamp frame ensures quick, leak-free installation in existing ductwork or extraction arms. Below we detail its technical specifications, advantages, and the value it brings to your welding operations.
Key Features & Technical Specifications
- HEPA-Level Filtration: Captures 99.97% of airborne particles at 0.3 microns, including welding fumes, grinding dust, and smoke.
- Polyester Media: High tensile strength, low pressure drop, and resistance to moisture and chemicals – ideal for industrial environments.
- Flange-Clamp Design: Pre-assembled metal flanges with clamping mechanism for easy attachment to extraction hoods, arms, or ducts without tools.
- Wide Operating Temperature: Continuous use up to 80°C (176°F) with peak tolerance up to 120°C (248°F), suitable for hot welding fumes.
- Customizable Dimensions: Available in standard sizes (e.g., 500×500 mm, 600×600 mm) or custom shapes to fit your system.
- Low Maintenance: Extended service life compared to standard filters; replacement intervals depend on fume load but typically 3–6 months.

Benefits for Your Welding Operation
- Worker Health Protection: Removes carcinogenic hexavalent chromium, manganese, and other toxic metal fumes, reducing respiratory risks and ensuring compliance with OSHA/EPA standards.
- Improved Weld Quality: Clean air around the weld zone minimizes contamination, leading to stronger, defect-free welds.
- Extended Equipment Life: Prevents fine dust from accumulating on machinery, electronics, and ventilation fans, reducing downtime and repair costs.
- Energy Savings: Low pressure drop design means your extraction system uses less energy to maintain required airflow, lowering electricity bills.
- Easy Installation & Replacement: The flange-clamp system allows one-person mounting in minutes; no special tools or adhesives needed.
- Custom Solutions: We can tailor the filter size, thickness, and gasket material to match your existing extraction arm or cabinet.

Frequently Asked Questions (FAQ)
-
Q: Is this filter suitable for MIG/TIG welding fumes?
A: Yes, it effectively captures fine particles from MIG, TIG, stick, and flux-cored welding, including metal oxides and fumes. -
Q: What is the recommended replacement interval?
A: Under typical 8-hour shift usage, we recommend replacing every 3–6 months, depending on fume concentration. Monitor pressure drop as an indicator. -
Q: Can I use this filter in a portable extraction arm?
A: Absolutely. The flange-clamp design easily attaches to standard extraction arms (e.g., 150mm, 200mm diameter). -
Q: Does the filter have any certifications?
A: Our filters are manufactured to meet HEPA H13 performance standards (EN 1822). Specific certifications can be provided upon request for your compliance needs. -
Q: What sizes do you offer?
A: We stock standard sizes such as 500×500×50mm, 600×600×50mm, and 400×400×50mm. Custom dimensions are available for orders above 100 pieces. -
Q: Is the polyester media washable?
A: No, this is a disposable filter. Washing can damage the HEPA layer and reduce efficiency. Replace with a new element when clogged. -
Q: Can I get a sample before bulk order?
A: Yes, we offer sample filters (small quantity) with shipping cost covered by the buyer. Sample orders are typically shipped within 7 days. -
Q: How do I install the flange-clamp filter?
A: Simply slide the filter into the duct or extraction hood, align the flange holes, and tighten the clamp bolts. No tools required for most models.
