|  | FR-4 Activated Charcoal | 
| Model Number: FR-4 | |
| Steam activated charcoal or coconut shell carbon is effective in adsorbing most commonly found organic vapors and odors. It can adsorb up to 50% of its own weight in some cases with the average being 33 1/3%. Standard activated carbon does not have much capacity for some reactive gases. Where gases are chemically reactive, specially impregnated carbon can be recommended.                                  |
