Air filter with an air pillow system having liquid separation capabilities

An air pillow liquid separation system includes housing with a plurality of air pillow pockets arranged within. An airflow stream enters the housing and is redirected, separating entrained liquids from the airflow stream by inertia effects. The separated liquids are directed over the air pillow pockets where the liquids collect on the air pillow pocket ribs forming droplets flowing to a drain opening in the housing.
