Selection overview
Air & VOC Treatment selection starts with operating data
For ventilation, exhaust and vapor-control systems, carbon selection is driven by the VOC or odor profile, humidity, airflow and allowable pressure drop. Pellet or granular carbon is reviewed for physical adsorption duties; reactive gases require a separate industrial-gas assessment.
Recommended sourcing direction
Pellet activated carbon for controlled pressure drop in VOC and odor beds; granular carbon where the equipment and vapor duty favor GAC
The figures below are common sourcing references, not an application-performance guarantee. Final grade, test methods and batch limits are confirmed after the operating conditions are reviewed.
| Common pellet diameter | 1.5-8 mm available directions; 4 mm is widely requested |
|---|---|
| CTC activity | Typical pellet range: 40-90%; common grades are often 50-75% |
| Hardness | Typical pellet range: 90-97%; >=95% is a common target |
| Moisture | Typically <=5% |
| Apparent density | Typical pellet reference range: 400-700 g/L |
| Alternative gas tests | Butane activity, butane working capacity or a VOC-specific adsorption or breakthrough test |
Application data needed for grade matching
Gas composition, contaminant and concentration, humidity, temperature, airflow, bed dimensions, pressure-drop limit, target service life, quantity and destination.
Qualification boundary
Confirm suitability with the actual system and agreed test method
No single carbon removes every VOC or odor compound. Selection must reflect the actual vapor, humidity, airflow and breakthrough target; reactive gases require a separate industrial-gas review.
System qualification
Move from operating data to a defensible grade specification
The selection process separates system conditions from product properties so the quotation can state relevant tests and acceptance values.
Process factors to send
- Contaminant identity, concentration and competing vapors
- Humidity, temperature, airflow and operating schedule
- Bed depth, face velocity and maximum pressure drop
- Target outlet concentration, service life and replacement method
Recommended validation path
- Define the VOC, vapor or odor-control duty
- Choose pellet diameter or GAC mesh
- Select CTC, butane or contaminant-specific tests
- Confirm breakthrough target and safe change-out criteria
Performance boundary: Operating results depend on the actual system. A sample or pilot result should use an agreed method and representative conditions.

Timing starts after the product specification, packing, order documents and agreed payment conditions are confirmed.
Export terms by route
Qingdao or Tianjin are commonly used; the final loading port is confirmed with the route and trade term.
FAQ
Air & VOC Treatment sourcing questions
Its cylindrical shape supports controlled airflow and pressure drop. Diameter, bed depth and hardness still need to match the equipment.
Water vapor can compete for adsorption sites and reduce usable capacity for some organic vapors. Provide the expected humidity range so the carbon and bed design can be reviewed under representative conditions.
Provide contaminant identity and concentration, humidity, temperature, airflow, bed depth, pressure-drop limit, desired service life and replacement method.
