Absorption of activated charcoal as well as the capacity index
Capacity index (noncommittal data):
4 = good adsorption
Activated charcoal takes up between 20 and 50% of its dead weight in
gaseous materials. Average separating ability for gaseous materials in
this category is with approx.. 35% of the dead weight of the coal.
This category contains most smell-forming substances.
3 = satisfactory adsorption
Activated charcoal takes up between 10 and 20% of its dead weight.
Average receptiveness for gaseous materials in this category is
approx.. 15% of the dead weight of the activated charcoal.
2= Poor adsorption
Poor performance on materials which are not readily absorbed and the use is not recommended
1 = No adsorption
The adsorption lies so low that activated charcoal cannot be used
effectively against the chemical compound concerned.

All data without guarantee
Filter life expectancy example. A customer uses propanol (Isopropyl Alcohol) for a manual cleaning application. His consumption is approximately 50 grams per week. Propanol has a capacity index of “4” (between 20 to 50%) or approximately 35% by weight. Carbon consumption = 50g / .35 = 143 grams. With a filter capacity of 2.05Kg as with the BVX200 filtration systems, the filter will last 2050 / 143 = 14.33 weeks. Carbon weight for all OKI gas filters are as follows. FG‐BVX = 500 grams FG‐BVX200 = 2050 grams FIL22G010 and FIL22G020 = 11,000 grams. Tips for good gas extraction Dwell time, also known as "residence time", is the length of time it takes for air to pass through a gas filter element. Longer dwell times generally result in greater gas adsorption as the air remains in contact with carbon for a longer period, so the deeper the carbon filter, the better the extraction will be. Disposal of Filters saturated with Solvents (Activated Carbon) If the activated carbon filters are saturated with flammable vapors such as isopropyl alcohol, they have to be disposed of as hazardous waste by incineration. A lab test for the flash point is recommended. Disclaimer: The information provided is a guideline only. We do advise that you contact your local authority to obtain further information and other applicable regulations. NOTE: The tables within this document list the relative effectiveness of activated carbon on various materials. The listing does not imply that the construction materials for OK International filters and systems are impervious to all of the compounds shown. The life expectancy of any purification system is dependent on the concentration of the contaminants to which the system is exposed. Obviously, the consumption rate or life of the media will be shorter as the concentration of the gaseous contaminant increases. Also, be aware that in most real world cases there is no air stream with just one contaminant, but in almost always is accompanied by other gases. This must always be taken into consideration.
