Strong Adsorption Cartridge Chemical Filter - China Suppliers & Factory with Customizable Options
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.
This is the most commonly used and core carrier material. Source and Manufacturing: Produced from carbon-rich materials (such as coal, wood, coconut shells, nut shells) through high-temperature "activation." The activation process creates an extremely developed pore structure.
Key Characteristics: Enormous specific surface area (typically 500–1500 m²/g, equivalent to the area of a football field packed into a few grams of carbon). These micro pores capture gas molecules through physical adsorption.
Types:
🔹 Coal-based Carbon: Lower cost, widely used, contains some inorganic ash.
🔹 Wood-based Carbon: Has larger pore structures, often used for VOC adsorption.
🔹 Coconut Shell Carbon: Considered one of the highest quality activated carbons, with a highly developed micro structure, especially suitable for organic vapors and odor removal, high hardness, and low ash content.
Source and Manufacturing: A porous, highly dispersed alumina material.
Key Characteristics: Possesses high hardness and thermal stability. It has some inherent adsorption capacity but is 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.
Source and Manufacturing: A naturally occurring or synthetically produced micro crystalline aluminosilicate.
Key Characteristics: Its pores are uniform and regular in size, 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: Commonly used in 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.
