Eco-Fume Extraction Solutions
Addressing three heavy-fume industrial welding conditions — enclosed space welding, high-current continuous operations, and heavy component manufacturing — we offer fume extraction solutions fully compliant with EN 1093-5 and ISO 15012 standards.
Our systems achieve ≥95% fume capture efficiency while reducing energy consumption by 15%, setting a new benchmark for green welding.
01|Spot Welding in Automotive Manufacturing (Low-Current Intermittent Operation)

Working Environment and Hazard Level

Typical Setup:
Resistance spot welding stations on automotive body assembly lines (0.8mm galvanized sheets).

Fume Characteristics:
● Zinc vapor concentration >45%, reaching 8–12 mg/m³ (three times higher than OSHA exposure limits)
● Duty Cycle: 3 minutes welding / 2 minutes idle, up to 200 start-stops per day
02|Section Welding in Shipbuilding (Mid-Current Continuous Operation)
Recommended Solution

Working Environment and Hazard Level

Typical Setup:
Welding double-bottom sections of ship hulls (10mm AH36 steel plates).

Fume Characteristics:
●Manganese compound concentration of 5–8 mg/m³ (four times the safety threshold)
● Fume particle size between 0.1–1μm
● Continuous operation: 8 hours per shift with welding time exceeding 70%
