Cartridge Type Activated Carbon Filter
Cartridge Type Activated Carbon Filter is a molecular filtration solution with granular activated carbon, designed to reduce odors, volatile organic compounds and certain gas-phase contaminants in industrial and commercial ventilation systems.
Cylindrical cartridges filled with granular activated carbon are installed in a galvanized or painted steel support frame. The modular cartridge design allows the carbon type, number of cartridges and filter depth to be selected according to the application.

Granular Activated Carbon
What Is a Cartridge Type Activated Carbon Filter?
A cartridge type activated carbon filter is a modular gas-phase filtration system designed to adsorb gas molecules from the airflow onto the surface of granular activated carbon. Each cartridge has a cylindrical body that securely contains the activated carbon granules.
Filling the cartridges using a vibration-assisted method helps reduce the risk of air channels or voids forming between the granules. As a result, airflow can pass more evenly through the carbon bed, allowing more effective use of the available activated carbon volume.
The filter frame can be manufactured from galvanized or painted steel according to application requirements. An EPDM gasket on each cartridge helps reduce uncontrolled bypass airflow between the cartridge and the mounting surface.

Maintenance and Cartridge Replacement
The service life of activated carbon cartridges should not be determined solely by pressure drop. The carbon bed may lose adsorption capacity for the target contaminant before becoming physically clogged.
Cartridge replacement should be determined using inlet and outlet gas measurements, odor breakthrough, activated carbon sample analysis, estimated saturation calculations or planned service intervals.
When used cartridges are removed, the nature of the adsorbed chemicals should be considered. Appropriate personal protective equipment should be used, and the cartridges should be disposed of according to the facility’s waste management procedures.
