Activated Carbon

HS-AC Activated Carbon

Coconut shell activated carbon is commonly used in industry for removing pollutants in vapor phase. Hydrosil’s HS-AC is highly active granular activated carbon (GAC) manufactured via high temperature steam activation from selected grades of coconut shell. Coconut shell activated carbon is known for its high hardness, low dust, and low ash content. The HS-AC has high activity and large surface area ideal for removing constituents in vapor phase.

The HS-AC is commonly used in chemical processing, air stripper off-gas VOC removal, tank or sump air vents, respirators, API separator vents, etc. To see if the HS-AC removes a specific pollutant please see our Air Pollutants page, or contact a representative today.
