A Comparative Study on the Performance of Activated Carbon Canisters Using Different Purge Air Humidities 940299
Although concerns have been raised that the performance of activated carbon canisters will decrease when exposed to air at higher humidities, results of a recently conducted test program do not substantiate these concerns. The results show that the purge efficiency and the working capacity of canisters that are purged with air at 75 grains per pound of dry air (GPPDA) humidity are equal or greater than those obtained with 50 GPPDA humidity purging. The results have been submitted to the California Air Resources Board (ARB) for use in aligning their evaporative emission testing regulations with the regulations promulgated by the U. S. Environmental Protection Agency (EPA).
