Reliable Welding Fume Extraction Solution from an Experienced Manufacturer
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to manufacturing high-quality industrial ventilation components. With an annual export value exceeding US$5 million and shipping to major markets including North America, Europe, Southeast Asia, and the Middle East, we bring decades of expertise to every product. Our Circular Air-blowing Chimney for Welding Fume Extraction (200mm, 304 Stainless Steel, High Temperature Resistant) is engineered to effectively capture and remove hazardous welding fumes, smoke, and heat from the work environment, ensuring a safer and more productive workspace. This chimney is a core component of any efficient fume extraction system, designed to withstand the harsh conditions of continuous welding operations.
Key Features & Technical Specifications
- Material: Premium 304 stainless steel – excellent corrosion resistance, durability, and easy cleaning. Suitable for both indoor and outdoor installations.
- Diameter: 200mm (8 inches) – a widely used standard size compatible with most welding fume extraction ducts and hoods.
- Design: Circular air-blowing chimney – optimized airflow dynamics to efficiently draw fumes upward and away from the welding zone. Reduces turbulence and improves extraction efficiency.
- High Temperature Resistance: Capable of withstanding typical welding temperatures (up to 600°C / 1112°F). The 304 stainless steel maintains structural integrity even under thermal stress.
- Surface Finish: Available in polished or brushed finish, reducing smoke adhesion and facilitating maintenance.
- Custom Options: Length, wall thickness, flange type, and additional mounting brackets can be customized according to your system requirements.

Advantages for Your Welding Operations
- Improved Air Quality: Effectively removes welding fumes, dust, and harmful gases (e.g., ozone, nitrogen oxides) from the breathing zone, protecting workers' health.
- Enhanced Productivity: Clear visibility of the weld area reduces errors and rework. A cleaner environment also reduces equipment downtime due to soot accumulation.
- Long Service Life: 304 stainless steel resists oxidation, rust, and chemical attack from flux residues, ensuring years of reliable service even in high‑humidity or outdoor conditions.
- Easy Integration: The 200mm diameter matches standard ducting and fume extraction arms. Flanged ends allow quick connection to existing ventilation systems.
- Cost‑Effective: Manufactured in our own factory with strict quality control, we offer competitive pricing without compromising on material or workmanship.

Frequently Asked Questions (FAQ)
-
What types of welding processes does this chimney support?
This chimney is suitable for most common welding processes including MIG/MAG, TIG, stick welding, and flux‑cored arc welding. It effectively extracts fumes generated by these processes, provided the extraction system is properly sized and positioned. -
Can the chimney be used with a portable fume extractor or a central system?
Yes, the 200mm diameter is standard for both portable and central fume extraction systems. The flanged end connects easily to flexible hoses or rigid ducts. If your system uses a different diameter, we can provide adapter rings or custom flanges. -
What is the maximum temperature this chimney can withstand?
304 stainless steel is rated for continuous service up to approximately 600°C (1112°F). For intermittent peaks or higher temperatures, we recommend discussing alternative materials (e.g., 310S stainless steel) with our engineering team. -
Is the chimney supplied with mounting brackets or flanges?
Standard configuration includes a flanged end on one side (or both, upon request). Mounting brackets can be added as an option. Please specify your installation requirements when placing an order. -
Can I get a custom length or wall thickness?
Absolutely. We offer customization on length, wall thickness, and flange type. Minimum order quantities may apply. Contact us with your specifications for a tailored solution. -
How do I clean and maintain the chimney?
The smooth surface of 304 stainless steel resists smoke adhesion. Regular cleaning with a soft cloth and mild detergent is sufficient. Avoid abrasive cleaners that may scratch the surface. Periodic inspection of welds and flanges ensures long‑term performance. -
Do you offer samples before bulk purchase?
Yes, we can provide samples (paid or free depending on order value) to evaluate quality and fit. Please contact our sales representative to arrange sample shipment. -
What certifications does your factory hold?
Our manufacturing processes follow strict internal quality control standards. Specific certifications (e.g., ISO, CE) are not currently listed on our company profile, but we can provide material test certificates and inspection reports upon request. For certification requirements, please discuss with our team to see if we can accommodate.
