The Working Principle of Andreae Filters is INERTIA SEPARATION.

Principle
 Separation by inertia is the working principle of the Andreae Filter.  The airflow, loaded with paint particles (overspray), suffers several radical changes in direction.  The paint particles, heavier than air, follow tangent trajectories to the airflow.  Therefore, the paint particles accumulate in the holding pockets and the airflow leaves the filter virtually free of overspray.
ADVANTAGES

NO MIGRATION
The migration phenomenon is common when slow-drying coatings are used with mesh filters.  The airflow will pull out particles already trapped in the mesh.  Consequently, the particles already deposited will again be airborne and migrate through the system. 
With the Andreae Filter, the paint particles are deposited in the holding pocket, a dead end, outside of the air stream.HIGH HOLDING CAPACITY
With separation by inertia, the captured overspray is deposited outside of the airflow into holding pockets.  The bigger the pocket, the better holding capacity of the filter. 

The Andreae Filter has 2.5" deep holding pockets, giving the Andreae Filter a holding capacity up to 6 times higher than common mesh filters.

STABLE STATIC PRESSURE
Static pressure increases slowly with the accumulation of particles.  This has two advantages:  the finisher stays in an environment of clean air and the airflow around the parts to be coated stays uniform.
