Abstract
An air dryer cartridge assembly, used in a compressed air system, includes a rigid porous layer, a fibrous material layer, a diffusing layer and a desiccant for filtering and drying compressed air passing in a first direction during a charging cycle. The compressed air passes through diffusing layer, the fibrous material layer and the rigid porous layer in a second direction during a purging cycle. The desiccant, which is downstream of the rigid porous layer, the fibrous material layer and the diffusing layer during the charging cycle, reduces moisture in the compressed air during the charging cycle. The use of diffusing layer downstream of the fibrous material layer during a charging cycle disperses the compressed air so that moisture removal is improved in the desiccant.
