Strong Adsorption Cartridge Chemical Filter - China Suppliers and Factory for High-Quality Air Filtration Solutions
It is widely used in Industrial And Commercial Ventilation Systems Such As Semiconductors, Electronics Factories, Pharmaceutical Factories, Chemical Factories, Museums, Luxury Office Buildings, Etc.
The physical foundation that constitutes the main structure of the filter cartridge and provides a massive adsorption surface area.
Activated Carbon
The most commonly used and core carrier material. Produced from carbon-rich materials (such as coal, wood, coconut shells, nut shells) through high-temperature "activation," creating an extremely developed pore structure.
Key Characteristics: Enormous specific surface area (typically 500–1500 m²/g). Micro-pores capture gas molecules through physical adsorption.
Types:
• Coal-based Carbon: Lower cost, widely used, contains some inorganic ash.
• Wood-based Carbon: Larger pore structures, often used for VOC adsorption.
• Coconut Shell Carbon: Highest quality, highly developed micro structure, especially suitable for organic vapors and odor removal, high hardness, and low ash content.
Activated Alumina
A porous, highly dispersed alumina material with high hardness and thermal stability.
More commonly used as an impregnated carrier because it can effectively support chemical reagents (e.g., potassium).
Application: Often used in formaldehyde filter cartridges and certain specific chemical filter cartridges.
Zeolite (Molecular Sieve)
A naturally occurring or synthetically produced micro-crystalline aluminosilicate.
Key Characteristics: Uniform and regular pore sizes, exhibiting molecular size selectivity — allowing it to sieve and adsorb molecules of specific sizes and polarities.
Hydrophobic zeolites outperform activated carbon in adsorbing organic gases under humid conditions.
Application: Industrial separation processes requiring high adsorption selectivity, or as a carrier for special impregnating agents.
The efficiency depends on the carbon content, normally ranging from 2.0 to 4.0, and can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.


As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded.
Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow. When this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.
Remarks: (1) Initial resistance tolerance of ± 10% (2) Support customer size
