When sparks fly and welding fumes fill the air, every workshop owner’s top concern should be worker health, regulatory compliance, and productivity. A welding extraction system isn’t just a luxury—it’s a critical safety investment. In this comprehensive guide, Shanghai Kaisen Environmental Technology Co., Ltd explores the ins and outs of welding extraction systems to help you select the right solution for your needs.
Why Do You Need a Welding Extraction System?
Every welding process releases hazardous fumes, toxic gases, and ultrafine particles that can jeopardize respiratory health and workplace safety. A high-quality welding extraction system:
-
Reduces exposure to harmful substances like metal oxides and solvents
-
Ensures compliance with occupational safety standards (e.g., OSHA, EU regulations)
-
Enhances visibility and workshop cleanliness
-
Prevents residual buildup on equipment and surfaces
Shanghai Kaisen Environmental Technology Co., Ltd emphasizes that the right extraction system transforms a dangerous environment into a safe, efficient workspace.
Types of Welding Extraction Systems
1. Benchtop Fume Extractors
Compact units designed for light or intermittent welding tasks. These systems typically include a flexible arm and replaceable filter cartridges, making them ideal for maintenance and repair shops.
2. Mobile Extraction Units
Portable systems mounted on wheels, suitable for site work and on-the-go applications. Equipped with stronger suction and larger filter capacities, mobile extractors serve a wide range of welding operations.
3. Centralized Extraction Systems
Engineered for workshops with multiple welding stations, centralized systems feature a wall-mounted or rooftop fan unit with ducting to each station. Shanghai Kaisen Environmental Technology Co., Ltd’s turnkey centralized solutions ensure optimized airflow for entire plants.
4. Integrated Bench Systems
These combine an extraction system with a worktable, capturing fumes directly inside or below the bench. Ideal for high-volume welding operations, these systems are a seamless integration of workstation and safety device.
Key Features to Consider
Filtration Efficiency
Look for HEPA or ULPA grades with at least 99.97% efficiency for particles ≥0.3 μm. Activated carbon or specialized chemical filters are crucial for neutralizing gases and VOCs.
Airflow Rate (CFM/m³/h)
Your welding extraction system needs sufficient airflow to capture fumes before dispersal. Shanghai Kaisen Environmental builds systems offering up to 6,000 m³/h to handle large-scale operations.
Mobility & Setup
Choose portable units for flexibility, stationary extractors for fixed environments. Centralized systems require professional ductwork installation.
Noise Levels & Energy Use
Low-noise units (<70 dB) enhance working conditions, while high-efficiency motors reduce energy costs and improve ROI.
Filter Maintenance & Safety Features
Opt for tool-less filter access, ease of replacement, automatic clog detection, and spark arrestors to minimize maintenance downtime and hazard risks.
How to Size a Welding Extraction System
-
Define Your Welding Type
MIG, TIG, arc welding, plasma cutting—each produces different fume profiles. -
Count Down the Stations
Industrial workshops may need a central system servicing multiple stations. -
Estimate Fume Load
Consider intensity, duration, and electrode types. Heavy-duty stainless or galvanized steel welding demands higher airflow systems. -
Consult Manufacturer Specs
Shanghai Kaisen Environmental provides detailed sizing charts and ventilation plans to align system capacity with your setup.
Installation & Maintenance Tips
-
Position Suction Points
Keep intake arms 5–15 cm from the fume source for optimal capture. -
Use Smooth, Short Ducting
Longer or accordion-style hoses reduce suction performance. -
Implement Regular Filter Checks
Dirty filters can diminish airflow and increase noise. Employ pre-filter layers to extend the lifespan of primary filters. -
Train Staff
Proper extraction system usage—adjusting arms, sanitizing filter drums, scheduling replacements—drastically improves performance.
