GC 4x8S

Coconut Shell Granular Activated Carbon

GC 4x8S granular activated carbon is ideal for most air purification purposes. Made from selected grades of coconut shell, its superior level of hardness makes it cleaner than most other carbons and gives it longer life expectancy. This, combined with its high activity level, makes it well suited for use in any kind of carbon filter or system.

GC 4x8S Pressure Drop Curve


Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable Local, State and Federal guidelines.
