3'HIGH X 30' WIDE ANDREAE FILT
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.
