Our latest Kraft Perforated HIGH EFFICIENCY FILTERS are designed to capture any wet solids or liquid particles in an air stream: high solid enamels, baked and air dried enamels, glues, oils, stains, lacquers, fiberglass, epoxies, asphalts, clear coats, tar, teflon, etc. We Automotive Solutions™ provide an international quality Filter Media with the purpose to protect & stop the Paint Entering in Atmosphere help maintain pollution norms.
The Working Principle of Kraft Perforated Filters is INERTIA SEPARATION.
PrincipleSeparation by inertia is the working principle of the Kraft Perforated Filters. 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 of Kraft Perforated Paint Stop Filter :
The v-shaped front wall prevents overspray bounce back and particle migration.
The deeper v-shape back wall captures overspray and deposits it outside of the airflow.
The filter exhaust holes are positioned to maintain constant airflow during the loading phase.
Static pressure increases slowly with the accumulation of overspray resulting in uniform airflow.

NO MIGRATION TO USE KRAFT PERFORATED PAINT STOP FILTER 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 CapacityWith 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. These 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 PressureStatic 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.
