The Activated Carbon Filter Module is the core gaseous pollutant purification component of smoke extraction systems. It is specifically engineered for the precise removal of formaldehyde, VOCs, odors, and various toxic gases. Utilizing high-iodine-value modified activated carbon combined with an innovative honeycomb composite structure, the module employs a dual purification mechanism of physical adsorption and chemical catalysis to efficiently decompose and retain harmful gaseous contaminants.
At the same time, the optimized airflow channel design ensures low pressure drop, enabling the module to meet stringent air quality requirements across industrial and residential applications.
Activated Carbon Matrix
Manufactured from premium coconut shell activated carbon and coal-based activated carbon, the media undergoes a specialized modification process that enhances iodine value and specific surface area. Compared to conventional activated carbon, adsorption capacity is increased by approximately 30%, allowing rapid and efficient capture of multiple gaseous pollutants.
Honeycomb Structure
The module utilizes aluminum honeycomb or ceramic honeycomb substrates as the structural carrier. This design significantly increases the contact area between airflow and activated carbon while simultaneously reducing airflow resistance, achieving an optimal balance between high adsorption efficiency and low pressure drop.
Broad-Spectrum, High-Efficiency Adsorption
Delivers powerful purification across a wide range of gaseous pollutants, with adsorption efficiencies of ≥95% for formaldehyde, ≥90% for benzene-series compounds, and ≥98% for hydrogen sulfide, effectively covering common toxic gases and odors.
Long-Lasting & Stable Purification Performance
Employing graded microporous and mesoporous adsorption technology, the module features an optimized pore structure distribution. Contaminant holding capacity is increased by 50% compared to standard products, with a service life ranging from 6 to 24 months, depending on actual gas concentration levels, thereby reducing maintenance and operating costs.
Low-Resistance, Energy-Efficient Design
The honeycomb airflow structure significantly optimizes gas flow paths. At an airflow velocity of 1 m/s, pressure drop remains ≤80 Pa, ensuring precise compatibility with various KNOKOO smoke extraction system models. Reduced fan load leads to an approximate 20% reduction in energy consumption.
Ensure the airflow direction matches the directional marking on the filter module during installation. Reverse or tilted installation is strictly prohibited, as it may compromise purification efficiency and service life.
The filter module must be replaced promptly under the following conditions:
① Noticeable reappearance of odors at the air outlet, indicating reduced purification performance;
② Operating pressure differential reaches twice the initial value.
Do not wash with water or expose to high-temperature baking, as this may permanently damage the pore structure of the activated carbon and result in irreversible adsorption performance loss.
Avoid prolonged exposure to environments with relative humidity above 80%, as moisture saturation may significantly reduce the adsorption efficiency for gaseous pollutants.
