Fume Extractor: A “Green Shield” for Industrial Welding Workshops

I. Welding Fumes: The “Invisible Threat” in Workshops

Welding produces harmful substances such as metal oxides and ozone, which can easily lead to welder’s pneumoconiosis and respiratory diseases. These fumes also reduce workshop visibility and affect operation accuracy. Without proper treatment, PM2.5 levels can exceed safety limits by more than ten times, posing a dual threat to both health and productivity.

II. KNOKOO FES150: The “Purification Powerhouse” for Welding Workshops

(1) Triple Filtration for 99.97% Purification Efficiency
The three-stage filtration system—Pre-filter + HEPA filter + Activated carbon layer—offers comprehensive protection. The pre-filter captures welding spatter and extends filter life, the HEPA filter efficiently traps particles as small as 0.3 microns, and the activated carbon layer absorbs harmful gases and odors. The purified air meets GB16297 standards, and each filter can be replaced independently to reduce maintenance costs.

(2) Powerful Yet Energy-Efficient – Reducing Costs and Boosting Efficiency
Equipped with a 150W variable frequency DC motor, the FES150 delivers a high airflow of 278m³/h. The 360° adjustable fume arm captures fumes directly at the source. Compared with traditional models, it saves up to 40% energy, increases filter dust-holding capacity by 50%, and extends filter replacement intervals to 6–8 months—cutting annual maintenance costs by 30%.

(3) Industrial-Grade Durability
The full-metal body is impact-resistant and heat-tolerant. Hidden side handles and universal casters ensure easy mobility. The system also includes power-off protection, while the flexible fume arm resists bending and accommodates frequent workstation adjustments.

III. Real-World Results: From “Smoky Haze” to “Clean Air”

A single unit covers an area of 20–30㎡, ideal for TIG welding, automated welding lines, and similar setups. After installation, PM2.5 levels in the workshop can drop from 500μg/m³ to below 50μg/m³. Reports show a 70% reduction in worker discomfort and a 60% decrease in equipment malfunction frequency.

IV. Compliance and Health Protection for Enterprises

The FES150 meets authoritative certification standards, and the purified exhaust can be safely released indoors—helping enterprises easily pass environmental assessments. A cleaner workspace reduces employee sick days, lowers hidden labor costs, and enhances the company’s ESG (Environmental, Social, and Governance) image and brand reputation.
