Impregnated Activated Carbon for Ammonia Treatment

GC IPA is a granular activated carbon derived from bituminous coal and specially impregnated for the removal of ammonia from vapor streams. It is also available in other mesh sizes as well as in a coconut shell base or pelletized form.

*Standard packaging is in 55lb and 1,100lb vinyl bags. Other packaging is available upon request with an additional cost.

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.
