KNOKOO Upgraded 5.5cm Thickness Medium Efficiency Filter Cartridge For FES150 Solder Fume Extractor

1. Product Positioning and Core Advantages

This product is an upgraded medium-efficiency filter cartridge developed by KNOKOO for the FES150 welding fume purifier. Compared to the previous model, the core improvement lies in increasing the thickness to 5.5cm, bringing two key advantages:

Upgraded Filtration Efficiency: The thicker filter material structure can deeply intercept pollutants, reducing the penetration rate of harmful particles and resulting in more stable purification effects;

Extended Service Life: The increased filter material capacity can hold more pollutants. Under the same usage intensity, the replacement cycle is extended by 20%-30% compared to the previous model, reducing long-term operating costs.

2. Superior Materials and Scientific Structure
The filter media is made of high-quality ultra-fine polyester fiber and electrostatic electret material composite, combined with a "multi-layer gradient structure" design, achieving the dual characteristics of "high-efficiency filtration + low air resistance." It also possesses:
Environmentally friendly properties: Odorless and releases no harmful substances, meeting workshop air safety requirements;
Practical design: Clear and regular filter media pleats increase the filtration area while ensuring smooth airflow without affecting the purifier's suction power;
Lightweight features: Easy installation, requiring no additional tools, and can be completed by a single person.

3. Precise Fit and Wide Application
Exclusively designed for the KNOKOO FES150 welding fume purifier, with precise size matching (22.5 x 17.5 x 5.5 cm), ensuring a seamless fit after installation and avoiding air leakage and purification failure due to size deviations;
Application scenarios: Suitable for scenarios generating welding fumes such as electronic welding, hardware processing, and circuit board production. As a core component of air purification systems, it creates a healthy breathing environment for workshop personnel.

4. Powerful Filtration Capabilities
Targeting common pollutants in welding fume environments, achieving precise interception:
Particle Filtration: Effectively captures fine particles ≥0.3μm, including welding dust, asbestos fibers, etc., with filtration efficiency meeting industry standards for medium-efficiency filter elements;
Hazardous Substance Adsorption: Adsorbs harmful components such as tar and volatile organic pollutants (VOCs) in welding fumes, reducing the concentration of harmful substances in the air and lowering occupational health risks.

III. Usage and Maintenance Guidelines

1. Reasonable Replacement Cycle

Recommended replacement interval: 3-8 months, subject to adjustment based on equipment usage intensity (e.g., daily operating time) and environmental pollutant concentration (e.g., number of welded workpieces);

Related maintenance reminder: Regularly replacing the pre-filter (if the equipment is equipped with one) can reduce the pollutant load on the medium-efficiency filter, further extending its service life and reducing overall consumable costs.

2. Replacement Judgment and Operation

Replacement Signals: The filter element needs to be replaced promptly when the following conditions occur:

The purifier's suction power decreases significantly, failing to effectively capture welding fumes;

The filter media surface shows obvious yellowing or blackening (tar or dust accumulation);

Visible particle accumulation on the filter element surface, or dust spots appearing on the airflow outlet side (indicating the filter media is saturated and has begun to allow dust to pass through);

Installation Notes: Strictly follow the equipment instruction manual for installation, ensuring the airflow direction is consistent with the internal structure of the filter element (the airflow direction is usually marked on the filter element). Avoid reverse installation, which will reduce purification efficiency.

3. Important Usage Instructions

Do Not Wash: The filter cartridge is a disposable consumable. Washing will damage the filter media structure (such as the electrostatic electret layer falling off or fibers deforming), leading to filtration failure. Do not wash or wipe.

Avoid Damage: Do not impact or squeeze the filter media during handling and installation to prevent wrinkling, deformation, or damage, which will affect the filtration effect.

High-Temperature Adaptability: If the ambient temperature exceeds 100℃, a special high-temperature resistant filter cartridge must be selected (this model is for standard temperature use; for high-temperature scenarios, please contact customer service for customization).

Pre-Cleanup: Before installing a new filter cartridge, check and clean any residual dust from the air ducts and air inlets inside the purifier to prevent old dust from adhering to the new filter cartridge and causing secondary pollution.

Original Manufacturer Compatibility Recommendation: Prioritize using KNOKOO original manufacturer filter cartridges. Their material and structure are highly compatible with the performance of the FES150 purifier, ensuring stable operation and extending the overall lifespan of the purifier. (Non-original manufacturer filter cartridges may increase the risk of equipment failure due to quality differences.)

IV.Packaging and After-Sales Service

Packaging Specifications: Single box size is 28-228cm, protected by a cardboard box to prevent filter element deformation during transportation. Each box contains 1 filter element.

After-Sales Support: Online after-sales consultation service is provided. For installation questions, size discrepancies (rare probability), or other issues, please contact customer service for solutions at any time.

Important Note: This product is not covered by warranty (as is standard for consumables). It is recommended to stock up in advance according to usage needs to avoid production disruptions due to untimely filter element replacement.
