Abstract
Oil entrained in purge air from a vehicle air dryer is directed through a purge air cleaner to remove the oil before discharge of the purge air to the environment. An absorbent material, perferably hydrophobic, is enclosed in the purge air cleaner, which may be safely disposed. Alternatively, oil can be extracted from the absorbent media and thereby recycled. By providing a spin-on type canister, the absorbent media can be easily replaced and serviced.
