CE certified KNOKOO FES600 Level 4 fume extractor filter intercepts 0.3μm particles spark protection

KNOKOO FES600-set 20kg Four-Stage Filter Set: The "Industrial-Grade Purification Core" of the FES600 Fume Extractor

Still worried about sparks igniting filter cartridges in industrial welding workshops? Is your FES600 fume extractor unable to absorb dense fumes, leading to customer complaints about strong workshop odors? Is discarding the entire set when changing filters wasteful and costly? The KNOKOO FES600 dedicated fume extractor filter set features a four-stage design: "fireproof filter + pre-filter + glass fiber filter + activated carbon filter." Its 20kg large-capacity activated carbon effectively adsorbs harmful gases, intercepts 99.97% of 0.3μm fine particles, and also prevents welding sparks, making it suitable for high-pollution scenarios such as industrial soldering and laser cutting—protecting equipment safety while reducing consumable costs, ensuring workshop air always meets industrial hygiene standards.

Product Description:

I. Core Advantages

1. Four-stage deep filtration + fireproof design, ensuring safer industrial-grade purification

First-stage fireproof filter: Intercepts welding sparks and metal sparks (such as high-temperature sparks from MIG and TIG welding). Washable and reusable, preventing sparks from igniting subsequent filter cartridges and causing safety hazards, extending the overall lifespan of the fume extractor.

Second-stage pre-filter (10-piece pack): Intercepts PM60 particles (such as welding metal shavings and laser cutting residue). Replace one piece every 10-60 days. High dust capacity reduces downstream filter cartridge clogging. 10 pieces meet the workshop's needs for 1-2 quarters.

Third-stage fiberglass medium-efficiency filter: Precisely captures fine particles ≥0.3μm (such as welding fumes and laser engraving dust), with a filtration efficiency of 99.97%. Replace one piece every 2-3 months. First, it prevents fine particles from entering the breathing zone, reducing the risk of occupational diseases for employees.

The fourth layer is a large-capacity activated carbon main filter: high-iodine-value activated carbon effectively adsorbs harmful gases and odors (such as welding ozone, VOCs, and burnt cutting smells). It needs to be replaced every 3-6 months, and its adsorption capacity is 3 times higher than ordinary activated carbon, quickly eliminating odors in the workshop.

Benefits: The four-stage filter works in synergy, covering the entire chain of "safety protection → large particles → fine particles → harmful gases," suitable for industrial workshops operating continuously for 8 hours a day, without the need for additional purification equipment.

2. Individual Replacement + Reusability: More Efficient Industrial-Grade Cost Control

Independent Layer Replacement: Avoid discarding the entire filter due to wear and tear on a single layer. For example, replace only one pre-filter when it becomes dirty (low cost), and replace the main filter only when the activated carbon filter is saturated. Compared to replacing the entire set, annual consumable costs are reduced by more than 50% (based on 3 FES600 units in a workshop, saving over 12,000 RMB annually).

Washable and Reusable Fireproof Filter: Avoid frequent replacement of the fireproof filter. When the surface dust reaches 70%, simply rinse with water and dry before reuse. The cost per use is close to zero, further reducing consumable expenditure.

Details: Each filter element is labeled with its replacement cycle and judgment criteria (e.g., "Replace when pre-filter becomes heavily soiled and suction decreases"). Workshop maintenance personnel can accurately judge the situation without specialized knowledge, avoiding excessive replacement waste.

3. Large Capacity + Industrial-Grade Materials, Suitable for High-Load Scenarios

20kg High Iodine Value Activated Carbon: Adsorption capacity is 3 times higher than ordinary small-capacity activated carbon, capable of handling high concentrations of harmful gases in industrial workshops (such as the amount of smoke from 10 welding workers operating simultaneously). Replacement is only needed every 3-6 months, reducing downtime for filter replacement.

Industrial-Grade Temperature-Resistant Filter Media: All filter elements can withstand ambient temperatures from -10℃ to 60℃, suitable for high-temperature and high-humidity workshop conditions (such as workshops without air conditioning in summer). The filter media is not easily deformed or delaminated, ensuring stable filtration efficiency.

Compatibility: Perfectly fits the FES600 fume extractor filter cartridge, requiring no cutting or adjustment. There is no airflow leakage after installation, ensuring that purification efficiency is not reduced even at a high airflow of 430m³/h.

• Avoid using non-original filters, as they may compromise the machine's performance and purification efficiency.

II. Frequently Asked Questions (Answers in Advance)

Q1: Is this filter set only compatible with the KNOKOO FES600? Can it be used with other brands of industrial-grade fume extractors?

Yes, this FES600-set filter is specifically designed for the KNOKOO FES600 industrial-grade fume extractor—the filter size and sealing structure are perfectly matched to the FES600 filter chamber (e.g., the activated carbon filter diameter and thickness match the main unit's airflow channel). Other brands of fume extractors can theoretically be used if their filter chamber parameters are the same as the FES600, but to ensure fire resistance and filtration efficiency (avoiding air leakage through gaps), it is recommended to use them primarily with the FES600. If you need compatibility with other models, please contact customer service with your equipment parameters, and we will recommend the corresponding industrial-grade fume extractor filter.

Q2: Is installing the activated carbon filter difficult? How many people are needed to operate it?

Featuring a modular design, the filter cartridge can be moved and installed by a single person. It also has a non-slip handle on the edge. After opening the FES600 fume extractor cartridge compartment, installation can be completed by a single person in 2 minutes, requiring no additional tools or multiple people, and will not delay workshop production (replacement can be completed during lunch breaks).

Q3: Will the filtration efficiency of the fireproof filter decrease after washing? Is there a requirement for the washing frequency?

The fireproof filter is made of high-temperature resistant fiberglass material. The filtration efficiency will not decrease after washing. It is recommended to wash it when the surface is 70% covered by dust and spark residue (approximately once every 1-2 months, adjusted according to the workshop's welding frequency). After rinsing with clean water, allow it to air dry naturally (avoid direct sunlight). It can be reused 5-8 times, fully meeting the high-frequency use needs of industrial workshops, and still maintains good spark interception capabilities after washing.

Q4: How long will 10 pre-filters last in the workshop? If the usage is large, can pre-filters be purchased separately?

Based on one FES600 machine in a workshop operating for 8 hours a day, a 10-piece pre-filter kit, replacing one piece every 10-60 days, can meet the needs of 100-600 days (approximately 3-20 months), sufficient for 1-2 years for small to medium-sized workshops. If the workshop has multiple FES600 machines or a high replacement frequency, contact customer service to purchase pre-filters separately (bulk orders of 10 pieces/pack or 50 pieces/box are supported). Bulk purchases enjoy exclusive discounts, further reducing consumable costs.

Q5: Will the filter cartridges mold in a high-temperature, high-humidity workshop? How should unused filter cartridges be stored?

The filter cartridges are moisture-proof (coated with a moisture-proof coating), and will not mold in workshop environments with humidity ≤60% and temperature ≤40℃. Unused filter cartridges are recommended to be stored in a dry, ventilated warehouse (avoiding water and heat sources), sealed in their original packaging. The shelf life is up to 1 year, and long-term storage will not affect the filtration effect.
