Addition of Coalescer Screen to Evaporator Assembly
The coalescer screen provides a barrier and collecting surface for water droplets which are expelled from the evaporator core. The "U" shaped
configuration in the direction of the airflow allows water to flow along the screen surface toward the edges of the blend door frame and downward to the
bottom of the evaporator housing.
