Are in-line adsorption filters affected in the same way as coalescing and dry particulate filers

In-line adsorption (activated carbon) filters often use the same housings as coalescing and dry particulate filters, looking identical externally.
These activated carbon filters however work differently to coalescing and dry particulate filters. They utilize a bed of activated carbon to remove oil vapors (gaseous oil) from the compressed air. Activated carbon has a fixed capacity to adsorb oil vapor and once this is used up, their elements or cartridges must be replaced.
Smaller, in-line style activated carbon filters are typically matched to the system flow rate and pipe connections. The inlet concentration of oil vapor, the presence of liquid oil as well as the temperature, pressure and dewpoint of the air all affect the life of these elements and in-line AC elements require frequent changes throughout the year to provide technically oil free compressed air.
