Abstract
An air return bulkhead having a filter for filtering dust, dirt and debris out of an airflow prior to its entry into an evaporator or heat exchanger. The apparatus is particularly designed for use within a climate-controlled space such as a trailer or truck interior. Air pulled into the refrigeration system first enters the air return bulkhead where particles and debris are filtered. The air then travels through the refrigeration system and back into the climate-controlled space.
