Andreae Concertina Filters
Andreae filters are the leading manufacturer of these Concertina Filters. Andreae, in fact, invented the original design. Andreae Team SA is specialized in developing, producing and marketing exhaust filtration products for spray booths since 1963.
Unique in design and working principle, Andreae Filters hold more paint particles than other exhaust filter media while maintaining uniform air flow around the parts being sprayed. This contributes to a cleaner air environment for the worker and the community at large. Andreae Filters are EPA compliant, easy to install and dispose, and last longer than fiberglass, expanded paper, polyester or styrofoam media.
THE ANDREAE RANGE OF FILTERS CAPTURE ANY SOLID OR LIQUID PARTICLE CONTAINED IN AN AIR STREAM.
The Working Principle of Andreae Filters is INERTIA SEPARATION. 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.
