Andreae 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.

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.
