KNOKOO Replacement Filter Set 4 Layers For FES350 Laser Fume Extractor

Product Description:

1. Composition

This replacement filter set includes:

• 1 Main Filter

• 2 Medium Filters

• 10 Pre-filters

The four-layer filtration system offers significantly larger dust capacity compared to single-layer filters, ensuring effective removal of harmful gases and smoke particles for cleaner air.

2. Filtration Layers

• Pre-Filter (First Layer):Made of thickened fiber material with laser-cut precision, this layer features smooth external surfaces and high filtration accuracy. It effectively traps larger particles and reduces clogging, ensuring better performance of subsequent filters.

• Medium Filter (Second Layer):Constructed using high-quality 3M materials, this filter features a sealed filling process that prevents smoke leakage and has a large dust-holding capacity. It filters out the majority of fine particles, reducing the burden on the high-efficiency filter.

• Medium Active Carbon Filter (Third Layer):Designed to filter small particles that the upper layers cannot absorb, this active carbon filter also captures various odors produced during work, providing enhanced air purification.

• High-Efficiency Filter (Fourth Layer):The final layer is equipped with high-iodine value active carbon, designed to adsorb odors, toxic gases, and volatile organic compounds (VOCs), preventing secondary pollution and maintaining clean air.

3. Filtration Capabilities

• Pre-Filter:Effectively filters larger particles, reducing clogging and ensuring the filter system works efficiently for longer periods.

• Medium Filter:Filters out the vast majority of fine particulate matter, easing the load on the high-efficiency filter and extending its lifespan.

• Medium Active Carbon Filter:Absorbs smaller particles missed by the upper layers and effectively captures various odors generated during work processes, ensuring a cleaner, fresher environment.

• High-Efficiency Filter:Adsorbs various odors and harmful gases, including VOCs, with high efficiency, preventing secondary contamination and improving air quality in enclosed spaces.

4. Compatibility

• This filter set is specifically designed for the KNOKOO FES350 Fume Extractor, offering a perfect fit and reliable performance as a replacement for the original filters.

Product parameters:

Product use:

1. Replacement Cycle

• Pre-Filter: Recommended replacement every 10-60 days, depending on the level of contamination in the environment.

• Medium Filter: Replace every 3-6 months for optimal performance.

• Medium Active Carbon Filter: Replace every 3-6 months, depending on the amount of odor and gas buildup.

• High-Efficiency Filter: Recommended replacement every 6-12 months.

2. Replacement Indicators

• First Layer (Pre-Filter):When the pre-filter is covered with over 70% dust and oil stains, and the suction power decreases without being able to clean it, replace the pre-filter.

• Second Layer (Medium Filter):If the medium filter accumulates more than 70% dust and cleaning does not restore its effectiveness, it should be replaced.

• Third Layer (Medium Active Carbon Filter):When the filter has covered over 70% dust and the absorption of odors weakens, replace the filter to maintain efficiency.

• Fourth Layer (High-Efficiency Filter):When the high-efficiency filter shows over 70% dust coverage and reduced odor absorption, it should be replaced.

3. Maintenance and Care

• Routine Cleaning: Regular cleaning can help prolong the life of the filters, but avoid aggressive cleaning methods that may damage the filter material.

• Use Original Filters: Always use genuine filters to ensure proper filtration efficiency and avoid damage to the equipment.

• Periodic Checks: Inspect filters regularly for dust buildup and reduce strain on the system by replacing them at appropriate intervals.

4. Precautions

• Genuine Filters Only: To maintain the efficiency of the system and extend the lifespan of the extractor, always use original replacement filters.

• Storage and Use: Do not store or use the filters in high-temperature (over 60°C), humid, or flammable environments. This could cause malfunction or safety risks.

• Regular Replacements: To ensure continued effective filtration, periodically check and replace the filters. This maintains both performance and air quality.
