Activated carbon components for odor-control stages
Commercial kitchen exhaust systems can use multiple filtration stages. After grease and smoke are captured upstream, an activated carbon stage may be added to address remaining odors.
For equipment manufacturers, ventilation contractors and maintenance service providers, key project details include the installation size, replacement method, carbon format and whether the component must fit an existing ecology unit.
Carbon-stage materials and components to review
The formats below are not interchangeable kitchen-exhaust solutions. Send the existing component reference, drawing or sample so the construction and requested supply format can be reviewed before quotation. A size match alone does not confirm suitability for the odor-control duty.
- Activated carbon foam filter media
- Fibrous activated carbon filter media
- Flat-panel activated carbon filters
- Plastic honeycomb carbon modules
- Cut-to-size carbon media
- Custom carbon filter assemblies
What reaches the carbon stage?
Start with the air after the system's grease and smoke treatment. The carbon stage is not a substitute for that upstream treatment. Include the following conditions with the component dimensions and replacement details you already have.
| Topic | Information to provide |
|---|---|
| Upstream treatment | Describe how grease and smoke are treated before the carbon stage, and include the existing equipment reference when available. |
| Odor-control duty | Describe the cooking or process source, any available gas measurements and the project's odor-control requirement. Clearly identify what is still unknown. |
| Carbon-stage conditions | State the operating airflow, temperature, relative humidity and allowable pressure drop, with units and any known operating range. |
If any operating conditions are unknown, identify them as unknown rather than estimate them. For the gas-phase selection checks, see our HVAC carbon media guide. For replacement planning, see what determines activated carbon filter service life.
Who we work with
These solutions are intended for ecology unit manufacturers, kitchen ventilation companies, commercial kitchen equipment suppliers, HVAC project suppliers and maintenance teams that need replacement carbon components or project-specific carbon filter modules.
Frequently asked questions
Can you make carbon filter components to fit an existing unit?
Send us the filter size, frame construction, installation method and any available photos or drawings. We can then review possible custom component formats.
Do you supply raw media as well as finished components?
Yes. We can discuss raw carbon media, cut-to-size materials and custom finished carbon filter components.
Are these components suitable for ecology units?
An activated carbon component may be evaluated for the odor-control stage of an ecology unit. Selection must match both the component construction and the conditions at the carbon stage, including upstream grease and smoke treatment. Component fit alone does not establish a complete system solution.
Sources and scope
The U.S. EPA carbon adsorber overview and Halton's kitchen-exhaust system overview explain general adsorption and system-selection principles. They do not certify a Junkang product or establish its performance. This page concerns carbon-stage materials and components, not the design or performance of a complete kitchen-exhaust system.
