Abstract
A compact desiccant air breather with unidirectional air flow comprises a housing with a plurality of air inlets adjacent an upper end for air intake. A desiccant bed of water absorbing material is within the intake flow path of air and an air chamber is within the intake flow path of air downstream of the desiccant bed. A one-way inflow check valve is adjacent the desiccant bed between the desiccant bed and the air chamber and is configured to allow airflow from the desiccant bed material to the air chamber and to prevent reverse airflow. A coupling member has an air flow conduit there-through which is in fluid communication with the air chamber and forms an air intake flow path exit. A one-way exhaust check valve in fluid communication with the air chamber is configured to allow airflow from the air chamber to the exterior and to prevent reverse flow.
