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

In a welding workshop, sparks from TIG welding dance in the air as metallic fumes and the pungent odor of solder fill the workspace. These seemingly “normal” emissions often cause workers to cough or feel chest tightness — and long-term exposure can even lead to occupational pneumoconiosis. Beyond health risks, welding fumes settle on precision lenses and machine components, reducing accuracy, while unfiltered emissions may result in environmental fines or lost export orders.

The KNOKOO FES600 Medium-Sized Fume Purifier is designed precisely to address these challenges — a smart, efficient solution that builds a “green shield” of health, compliance, and productivity for modern welding environments.

1. Robust Protection: Five-Layer Filtration and Safety Design for a Cleaner, Safer Workshop

Welding fumes contain metal oxides, ozone, and other hazardous substances, often accompanied by sparks. The FES600 safeguards both workers and workshop safety through dual protection — complete purification and fire prevention.

(1) Five-Layer Tower Filtration System — 99.99% Purification Efficiency

Tailored for heavy smoke and strong odors, the FES600 adopts a five-stage vertical filtration structure that neutralizes contaminants at every level:

• Fireproof Steel Mesh (Top Layer): Blocks sparks and prevents ignition of the filter, eliminating fire hazards.

• Primary Filter: Captures large metal particles and welding slag, protecting downstream filters.

• Medium Filter: Removes fine dust particles smaller than 0.3 microns, such as tin dust from soldering.

• Activated Carbon Layer: Absorbs ozone and flux odors, eliminating pungent smells from the workspace.

• High-Efficiency Filter: Traps remaining micro-particles, ensuring exhaust air meets strict global environmental standards (e.g., EU CE, U.S. EPA).

The result is cleaner air, safer breathing, and easy environmental compliance for the enterprise.

(2) Fully Sealed Circulation — Protecting the Workshop Environment

The FES600 features a sealed internal structure with specialized sealing materials to ensure 100% of the fumes pass through the filtration system — preventing leakage or secondary pollution.
Its closed-loop internal air circulation maintains the workshop’s temperature and humidity, avoiding loss of conditioned air — particularly vital for precision electronics welding, where humidity control affects quality. The unit purifies the air without compromising production stability, achieving both environmental and operational efficiency.

2. Practical Adaptability: Flexible Design for Dynamic Welding Environments

Welding workshops often have scattered workstations (e.g., one-to-six manual soldering setups, TIG areas, reflow zones) and frequent equipment movement. The FES600 is engineered for maximum adaptability in such dynamic environments.

(1) Easy Mobility — Flexible Multi-Station Purification

Equipped with lockable silent PU casters, the FES600 can be easily moved by one person between soldering benches, TIG zones, and reflow lines — ensuring complete fume coverage without redundant equipment.
A 3-meter, 110mm high-temperature-resistant hose comes standard — durable, anti-aging, and flexible enough to connect directly to fume outlets. The adjustable length captures fumes at the source, preventing them from spreading across the workspace.

(2) Intuitive Operation — No Professional Training Needed

With digital display and key control, operators can easily monitor airflow and system status.
The remote control allows convenient on/off and airflow adjustment from the welding position, saving time and improving efficiency.
Installation is hassle-free — simply unpack and assemble in three steps, enabling same-day operation without production delays.

(3) Ten-Speed Adjustable Airflow — Matching Every Welding Scenario

Different welding methods produce varying fume densities — for instance, manual soldering creates light dispersed smoke, while TIG or reflow welding produces concentrated fumes.
The FES600 offers 10-step variable speed control:

• Use low-speed modes for light soldering to save energy.

• Switch to high-speed for heavy smoke conditions like TIG or wave soldering.

This ensures optimal balance between purification efficiency and energy conservation.

3. Long-Term Savings: Low Energy, Low Maintenance, Lower Operating Costs

For enterprises, a true “green solution” must be not only effective — but also cost-efficient and durable. The FES600 helps welding workshops achieve both short-term results and long-term savings.

(1) Energy-Efficient and Maintenance-Free — Cut Operating Costs

The high-speed brushless DC motor ensures stable, low-noise operation suitable for 24-hour continuous use, with a lifespan up to three times longer than conventional motors.
It consumes 40% less energy than standard purifiers, lowering daily electricity expenses.
No regular maintenance is required — saving thousands annually in servicing costs.

The aerospace-grade aluminum turbine impeller resists corrosion from welding fumes, and its dynamic balance calibration minimizes vibration and extends mechanical life — reducing breakdowns and repair costs.

(2) Modular Filter Replacement and Clogging Alarm — Cut Consumable Costs

The modular filter design allows each layer (pre-filter, medium, activated carbon, HEPA) to be replaced individually:
Replace only the pre-filter when dealing with high dust loads, or just the carbon layer when odor absorption declines — cutting filter consumption by up to 30%.

The built-in pressure differential sensor triggers a sound and light alarm when filters are clogged, preventing ineffective purification or premature replacement — maintaining both safety and cost efficiency.

4. Why Choose the FES600: Real “Green Upgrades” for Welding Workshops

For industrial welding operations, the KNOKOO FES600 is more than just a fume purifier — it’s a comprehensive solution that protects workers’ health, ensures production stability, and helps enterprises stay compliant with environmental standards.

Compatible with multiple applications — from 1-to-6 manual soldering lines to TIG, reflow, and wave welding — the FES600 combines five-layer filtration, flexible adaptability, and long-term cost savings to solve fume challenges effectively.

It transforms “green production” from a compliance burden into a competitive advantage, helping businesses create a safer, cleaner, and more sustainable workshop.
